Answers

I believe it will be A. Density, temperature, and viscosity, can be found in water through tests. Hope this helps! Mark as brainly please!

The property of water that is not critical to biological life is surface tension.

What is biological life?

Biological life means the life in which living organism do exist and for their survival they mainly depends on water and air.

The main critical properties that water should posses to biological life are density, temperature, cohesive force and adhesive force. Viscosity is also understand by the cohesive force because more attraction between atoms more viscous they are.

Hence option (1) is correct i.e. surface tension.

Show the work. Convert 150 mm Hg to psi.

pls help me, thanks

Answers

Answer:

2.9 psi

Explanation:

Pressure (mmHg) = 150 mmHg

Pressure (psi) =?

The pressure in pound per square inch (psi) can be obtained as follow:

51.715 mmHg = 1 psi

Therefore,

150 mmHg = 150 mmHg × 1 psi / 51.715 mmHg

150 mmHg = 2.9 psi

Thus, pressure in pound per square inch (psi) is 2.9 psi.

Compute the mass of KI needed to prepare 500 mL of a 0.750 M solution.

Answers

Answer:

62 grams

Explanation:

Molarity=mol/liter

We have mL and Molarity

500 mL * 1 L/1000 mL=0.5

Plug 0.5 in and solve for moles

0.75=mol/0.5

0.75*0.5=0.375 mol

Convert to grams by finding the mass of KI: 39+126.9= 165.9 grams

0.375 mol KI * 165.9 grams KI/1 mol KI= 62.2125 grams

The mass of KI needed is 124.5 grams, this can be calculated by adding the values in molarity formula.

What is Molarity?

It is defined as number of moles of solute over volume of solution in liters.

It is given by:

M = n/ V

What information do we have?

Molarity= 0.750 M

Volume = 500 mL= 1 L

Molar mass of KI = 166 g/mol

To find:

Mass of KI=?

On substituting the values:

M= n/V

0.750 M= n/ 1 L

n= 0.750 M* 1l

n= 0.750 moles

Number of moles is the ratio between mass and molar mass.

n= m/M

0.750 moles = m/ 166 g/mol

m= 0.750*166

m= 124.5 grams.

Thus, the mass of KI needed is 124.5 grams.

Explain how you know which coefficient to use for the specific compound.


Your Answer:

Answers

Answer:

2C8H18 + 25O2 -> 16CO2 + 18H2O

(16C, 36H, 50O)

H2O requires 2H per H2O, Meaning that you'd have 9H2O's from 1C8H18, but you still need that O2 for the CO2 and because the reactant side has 8C (within C8H18) You'd have to times the amount of required O2 from CO2 by 8. Even then you still don't have enough for both CO2 and H2O so you'll have to multiply MORE causing a bigger chain reaction resulting in 2C8H18 + 25O2 -> 16CO2 + 18H2O

Imagine the following scenario involving marbles as "radioactive isotopes".

Let's say the half-life of green marbles is 1 million years.

In one hand, you're holding 2 green marbles. In your other hand, you're holding 500,000 green marbles.

Hypothetically, noting that we have two different starting amounts of "isotopes", how long will it take for half of each amount to decay?

Answers

Answer:

1 million years

Explanation:

The half life of a radioactive isotope refers to the time it takes for the radioactive isotope to decay to half of its original amount.

The half life of a radioactive isotope is independent of the amount of starting material. Hence, whether the amount of starting material is small or large, the half life of the substance remains the same.

Hence the half life of 2 green marbles and 500,000 green marbles is 1 million years.

Steve and Meg are doing an experiment where they need to make 37 grams of Fe2O3. How many grams of Fe would they need ?

Answers

Answer:

25.9g

Explanation:

Molecular mass of Fe₂O₃ = (56 * 2) + (16 * 3)

                                          = 112 + 48 = 160

Let's follow the unitary method now

How could you reduce the boiling point of water in this system?


A. Increase the size of the flame

B. Decrease the volume of the water

C. Decrease the pressure to 0 atm.

D. Increase the pressure to 2 atm

Answers

Answer:

I think the answer will be number A

The boiling point of a substance is constant and for water it is 100 degree celsius. However by reducing the surrounding pressure the boiling point can be reduced.

What is boiling point ?

Boiling point of a substances is the temperature at which the vapor pressure of the gas phase above the liquid equals to the atmospheric pressure where, the liquid converts to the vapor state.

Boiling point depends on the bond type, molar mass, temperature and pressure. As the and pressure increases, boiling point increases. Similarly with an increasing mass and more strength intermolecular force results in greater boiling point.

As the atmospheric pressure decreases, the temperature needed to equalise the vapor pressure of the gas phase over the liquid also decreases. Hence, boiling point decreases. Therefore, option C is correct.

Answer:

1. Distance  = 5 cm

Displacement = 1 cm

2. Distance = 7 cm

Displacement = 1 cm

3. Distance = 5 cm

Displacement = -1 cm

4. Distance  = 6 cm

Displacement = -2 cm

5. Distance  = 4 cm

Displacement = 0 cm

Explanation:

The distance an object travels is a measure of the total ground cobpvered bybthe object without regard to the direction of motion. It is a scalar quantity as it only takes into account magnitude but not the direction of a quantity.

Displacement however, is a measure of how far away or apart an object is from its starting position.  It a vector quantity as it takes into account both the magnitude and direction in its measurement.

From the attachment provided, considering forward direction as positive and reverse as negative :

1. When a object moves from point 1 to point 4 and reverses to point 2.:

Distance  = from 1 to 4 = 3 cm; from 4 back to 2 = 2 cm;  3 + 2 = 5 cm

Displacement = from 1 to 4 = +3 cm; from 4 back to 2 = -2 cm;  3 - 2 = 1 cm

2. When an object moves from point 1 to 5 and reverses to 2:

Distance = from 1 to 5 = 4cm; from 5 back to 2 = 3 cm; 4 + 3 = 7 cm

Displacement = from 1 to 5 = +4 cm; from 5 back to 2 = -4 cm;  4 - 3 = 1 cm

3. When an object moves from point 1 to 3 and then reverses to 0.

Distance  = from 1 to 3 = 2 cm; from 3 back to 0 = 3 cm;  2 + 3 = 5 cm

Displacement = from 1 to 3 = +2 cm; from 3 back to 0 = -3 cm;  2 - 3 = -1 cm

4. When an object moves from point 3 to 5 and then reverses to 1:

Distance  = from 3 to 5 = 2 cm; from 5 back to 1 = 4 cm;  2 + 4 = 6 cm

Displacement = from 3 to 5 = +2 cm; from 5 back to 1 = -4 cm;  2 - 4 = -2 cm

5. When an object moves from point 2 to 4 and then reverses to 3.

Distance  = from 2 to 4 = 2 cm; from 4 back to 2 = 2 cm;  2 + 2 = 4 cm

Displacement = from 2 to 4 = +2 cm; from 4 back to 2 = -2 cm;  2 - 2 = 0 cm

What is the mass in grams of precipitate formed when 250.0 mL of 0.360 M ZnCl₂ is mixed with excess KOH in the following chemical reaction?
ZnCl₂ (aq) + 2 KOH (aq) → Zn(OH)₂ (s) + 2 KCl (aq)

Answers

Answer:

8.95 g

Explanation:

ZnCl₂ (aq) + 2 KOH (aq) → Zn(OH)₂ (s) + 2 KCl (aq)

First we calculate how many ZnCl₂ moles reacted, using the given concentration and volume:

250 mL / 1000 = 0.250 L0.360 M * 0.250 L = 0.090 mol ZnCl₂

Then we convert ZnCl₂ moles into Zn(OH)₂ moles [ Zn(OH)₂ is the precipitate, as it is the solid]:

0.090 mol ZnCl₂ * [tex]\frac{1molZn(OH)_2}{1molZnCl_2}[/tex] = 0.090 mol Zn(OH)₂

Finally we convert 0.090 Zn(OH)₂ moles into grams, using its molar mass:

0.090 mol Zn(OH)₂ * 99.424 g/mol = 8.95 g

The mass of a substance is the product of the molar mass and the moles of the substance. The mass of precipitate formed in the reaction is 8.95 gm.

What is Mass?

The mass of the substance is the weight of the compound or the molecule present in the sample.

The balanced chemical reaction is shown as:

[tex]\rm ZnCl_{2} (aq) + 2 KOH (aq) \rightarrow Zn(OH)_{2} (s) + 2 KCl (aq)[/tex]

Given,

Volume (V) of zinc chloride = 0.250 L

Molarity of zinc chloride (M) = 0.360M

Moles of zinc chloride are calculated as:

[tex]\begin{aligned} \rm moles &= \rm molarity \times volume \\\\&= 0.360 \times 0.250\\\\&= 0.090 \;\rm mol\end{aligned}[/tex]

Moles of zinc hydroxide from zinc chloride are calculated as:

[tex]0.090\;\rm mol \; ZnCl_{2} \times \dfrac{ 1\;\rm mol \;\rm Zn(OH)_{2}}{1\;\rm mol\; ZnCl_{2}} = 0.090 \;\rm mol[/tex]

Mass is calculated as:

[tex]\begin{aligned} \rm mass &= \rm moles \times molar \; mass\\\\&= 0.090 \times 99.424 \\\\&= 8.95 \;\rm gm\end{aligned}[/tex]

Therefore, 8.95 gm precipitate is formed.

Answers

Answer:

D.  Gas X has a lower density and effuses faster than Gas Y.

Explanation:

I took the test.

Lower Density = effuse/ diffuse fasterLower Molar Mass = effuse/ diffuse faster

Gas X has a lower density and effuses faster than Gas Y. Hence, option D is correct.

What is density?

Density is the amount or the number of entities that can be contained in an area. It is denoted by ρ and is calculated as,

ρ = Mass ÷ Volume

Diffusion is the process of movement of a substance from the area of higher concentration to the area of lower concentration.

Effusion  is the process of a gas being poured out through a hole diametrically smaller than the structural exit of the container.

The gas with a smaller mass will diffuse slower in rate than the gas with a higher mass.

Hence, Gas X has a lower density and effuses faster than Gas Y.
