An oil tanker holds 3.24 • 10^7 gallons of crude oil. The mass of the oil is 2.13 • 10^8 pounds. What is the density of the oil in kilograms per liter?

Answers

Answer

The density of the oil in kilograms per liter is 0.78775

Explanation

Note: 1 gallon = 3.78541 liters

1 pound = 0.453592 kilogram

Given:

The gallons (volume) of crude oil = 3.24 x 10⁷ gallons

The mass of the crude oil = 2.13 x 10⁸ pounds

Conversion:

The volume in liters of 3.24 x 10⁷ gallons of crude oil will be

[tex]\begin{gathered} =3.78541\times3.24\times10^7 \\ =1.22647\times10^8\text{ liters} \end{gathered}[/tex]

Also, the mass in kilograms of 2.13 x 10⁸ pounds of crude oil will be

[tex]\begin{gathered} =0.453592\times2.13\times10^8 \\ =9.6615\times10^7\text{ kilograms} \end{gathered}[/tex]

Now, we shall use the formula below to calculate the density

[tex]\begin{gathered} \text{Density = }\frac{Mass\text{ in kilograms}}{\text{Volume in liter}} \\ \text{Mass in kilograms = 9.6615 }\times10^7 \\ Volume\text{ in liters =}1.22647\times10^8 \\ \therefore Density\text{ in kilograms per liter = }\frac{\text{9.6615 }\times10^7}{1.22647\times10^8}=0.78775^{} \end{gathered}[/tex]

Answers

The equation of line u, given that it is parallel to line t is:

y = –17x – 113

How to determine the equation of line u

We know that the equation of straight line is given as

y = mx + c

Where

y is the coordinate on y-axis x is the coordinate on x-axis m is the slope or gradient c is the intercept on y-axis

First, we shall determine the slope of line u. This can be obtained as follow:

y = –17x – 2

Comparing y = mx + c with y = –17x – 2,

The slope (m₁) = –17

Recall,

The slope of parallel lines are equal.

Thus,

The slope of line u, is given as:

m₂ = m₁ = –17

Finally, we shall obtain the equation of line u as follow:

Coordinate = (7, 6) x coordinate 1 (x₁) = 7y coordinate 1 (y₁) = 6Slope of line u (m₂) = –17Equation of line u=?

y – y₁ = m₂(x – x₁)

y – 6 = –17(x – 7)

Clear bracket

y – 6 = –17x – 119

Rearrange

y = –17x – 119 + 6

y = –17x – 113

Thus, the equation of line u is y = –17x – 113

#SPJ1

Answer:

Equation of line is given as y = mx + c, where m is the gradient and c is the y-intercept.

Parallel lines have the same gradient so gradient of line u is -17.

Equation of line u is y = -17x + c

Substitute (7,6) into the equation to find c.

6 = -17(7) + c

c = 125

Hence, equation of line u is y = -17x + 125.

Answers

The energy released as heat when a typical table sugar cube of mass 1.5 g is burned in air is 24.78 KJ energy.

What is energy?

Energy is defined as the quantitative property that is transferred to a body or physical system and is visible in the performance of work as well as in the form of heat and light.

A. Table sugar is sucrose.

According to the data, its molecular formula is C12H22O11 and its molecular weight is 342 g when 1 mole of sucrose gives 5650 KJ/mole energy on combustion. 1.5 g equals 0.00438 moles of energy is 24.78 KJ.

B. According to Newton's laws, 25% of the above released energy is used for work, which equals 6.19 KJ.

6.19 KJ = 6190 joules

U= mgh

U= ENERGY = WORK

m = mass of the object here mass of a normal adult

g = gravity =9.8 m/s2

h = height in meters

The height that can be climbed based on the above data is = 12.63m.

C. When 1 mole of glucose gives 2805 KJ/mole energy on combustion, its molecular formula  is C6H12O6

Molecular weight is 180 g.

2.5 g equates to 0.0138 moles producing 38.95 kJ of energy.

D. 25% of the previously released energy is used for work, which means

According to Newton's laws, 9.73kJ is used.

9.73 KJ = 9730 joules

U= mgh

U= ENERGY = WORK

m = mass of the object here mass of a normal adult

g = gravity =9.8 m/s2

h = height in meters

Height = 19.85m based on the above data

Thus, the energy released as heat when a typical table sugar cube of mass 1.5 g is burned in air is 24.78 KJ energy.

Determine the total volume of all gases (at STP) formed when 50.0 mL of TNT (C3H5(NO3)3, d=1.60 g/mL, molar mass=227.10 g/mol reacts according to the following reaction

Answers

The total pressure would be 1189 atm.

What is pressure?

pressure is the force applied perpendicular to the surface of an object per unit area over which that force is distributed .

Sol-the reaction is -

4C3H5(NO3)3--->6N2+O2+12CO2+10H2O

As we have the volume of TNT .we must know the density to find out the mass and then, apply molar mass to calculate mole.

TNT density = 1.654 g/mL

Density = mass / volume

1.654 g/mL = TNT mass / 50mL

1.654 g/mL . 50mL = TNT mass → 82.7 g

Mass / Molar mass = Mol → 82.7 g / 227.1 g/m = 0.364 mole

Now, we can calculate all the mole for the formed gases.

4 mole of TNT produce 6 mole N₂ ___ 1 mol O₂ __ 12 mole dioxide __ 10 mole of water

0.364 mole of TNT will produce:

- (0.364  . 6) /4 = 0.546 mole of produced nitrogen

- (0.364 . 1) /4 =  0.091 mole of produced oxygen

- (0.364 . 12) /4 = 1.092 mole of produced dioxide

0.364 . 10) /4 = 0.91 mole of produced vapour of water.

Total mole = 0.564 + 0.091 + 1.092 + 0.91 = 2.657 mole

Let's apply the Ideal Gases Law to find the total pressure, at STP

In STP, pressure is 1 atm for 1 mole at 273K, in a volume of 22.4 mL

But we have a volume of 50mL, and we have 2.657 total mole

Don't forget to convert 50 mL to L, cause the units for R

50 mL = 0.050L

P . 0.050L = 2.657 mol . 0.082L.atm/mol.K . 273K

P = (2.657 mol . 0.082L.atm/mol.K . 273K) / 0.050L

Thus

Water has a higher solubility for lithium chloride than non-polar solvents.

Which types of orbitals are found in the principal energy level n=2?

Answers

The kind of orbitals precisely found in the principal energy level n=2 are the one 2s orbital and three 2p orbitals

Why the n=2 orbital has four orbitals?

In the second orbital, there are actually four different types of orbitals which are found here, these are:

The one 2s orbitalThe three 2p orbitals.

The position of elements in the periodic table is largely based on the shared electrons of atoms which are being technically distributed at various level.

An element is a substance which cannot be split into different forms by ordinary means. Electrons revolve around the orbits of atoms of elements.

NO2 has sp2 hybridization in the traditional sense.

Explanation:

Single electron orbitals are often pure, unhybridized p-orbitals, such those seen in the methyl free radical.

However, when the central atom is joined to strongly electronegative atoms or groups, the single electron orbital is said to be hybridized. It happens as a result of the core atom's decreasing electron density, which draws in odd electron orbital density and reduces the size of the odd electron orbital. As a result, the odd-electron orbital takes on some "s" character and becomes hybridized.

ClO2, ClO3, and CF3 are sp3 hybridized for the same reason.

Nitrogen is collect over water at 40 Celsius . The partial pressure due to water vapor is 7.38 kPA at 40 Celsius , what is the partial pressure of nitrogen if the total pressure is 99.42 kPa?

Answers

There is a partial pressure for each gas in a mixture of gases, which is the pressure that would exist if that gas alone filled the whole volume of the initial combination at the same temperature.

One of two methods can be used to compute partial pressures:

Use PV = nRT to calculate the individual pressure of each gas in a mixture.

Utilizing the mole fraction of each gas, determine the proportion of pressure from the total pressure that may be ascribed to each individual gas.

When attempting to predict gas movement, partial pressure must be taken into account. Recall that the pressure of gases usually equalizes across nearby locations. From one area with a greater partial pressure to another with a lower partial pressure, a gas will move.

By dividing the mole fraction by the total pressure of a gas, one can calculate its partial pressure. Since it is based solely on the quantity of particles present rather than the nature of the gas, the Ideal Gas Equation remains true for mixes of gases just as it does for pure gases.

Which of the following solutions has the highest boiling point?


Which of the following solutions has the lowest boiling point?

Answers

Boiling point of Alcl3 would be highest .

As, i of Na2S= 3

2) i of NaNO3= 2

3) i of Alcl3= 4

4) i of Sucrose= 1 (As it doesn't show any kind of dissociation)

5) i of Mg(clo4)2= 3

What is boiling point elevation?

Although we're assuming water as the solvent, boiling point elevation also depends on the solute concentration and the number of particles the solute breaks down into. The total number of particles in solution affects aggregative qualities like boiling point elevation. Here, water is the solvent. As a result, the boiling point of all solutions will be elevated above the boiling point of water.

Magnesium + Silver Nitrate →Determine the reaction typeFinish the word equationWrite a balanced chemical reactionFor Double displacement include a net ionic equation (you don’t know double displacement yet!)For single replacement state the transfer of electrons

Answers

Explanation:

For this question, we need to know that:

Magnesium is Mg

Silver Nitrate is AgNO3

So the complete and balanced reaction is:

Mg + 2 AgNO3 → Mg(NO3)2 + 2 Ag

Also, we need to know that is it a single replacement equation.

Single replacement reactions are those that occur between a compound substance (made up of more than one chemical element) and a simple substance (made up of only one type of chemical element), giving rise to another simple substance and another compound.

Generically, we have:

A + CD → AC + D

This is the case of this reaction.

Answer:

Determine the reaction type

Single replacement.

Finish the word equation

Magnesium + Silver Nitrate → Magnesium nitrate + silver

Write a balanced chemical reaction

Mg + 2 AgNO3 → Mg(NO3)2 + 2 Ag

For single replacement state the transfer of electrons

Electrons are transferred from magnesium to silver.

Carbohydrates serve as a vital source of chemical energy to the human body. Carbohydrates are broken down into smaller units of glucose, among other sugars, providing energy to various muscles and organs, including the brain. On average, for every 10.0 g of carbohydrates consumed, the body will store 170 kJ of energy.

Answers

The kilocalories of the 170KJ energy value = 40.6 kcal

What are carbohydrates?

Carbohydrate is defined as the major class of nutrients in food and food products that are organic macromolecule which are capable of giving body energy when broken down to its smallest unit called glucose.

The functions of carbohydrates in the body include the following:

They provide energy to the body.They spare the use of proteins in the body for energy.They assist in lipid metabolism.

For every 10 g of carbohydrates that is being consumed, 170 kilojoules of energy is obtained.

To convert 170 kilojoules to kilocalories;

1 kilocalorie = 4.184 kilojoules

X kcal = 170 kJ

make X kcal the subject of formula,

X kcal = 170/4.184

X kcal = 40.6 kilo calories.
