Spits

Answer:

yes yes it does

Explanation:

Considering the definition of the law of conservation of matter, the law of conservation of matter establishes that matter cannot be created or destroyed (option C).

The law of conservation of matter holds that, within a closed system, the amount of matter involved in a chemical reaction is constant, meaning a closed system means an environment that isolates the components involved in the reaction from the outside.

In other words, this law establishes that the mass of the reactants consumed is equal to the mass of the products obtained, even though they have been transformed into each other.

In other words, the law of conservation of matter states that matter is neither created nor destroyed during a chemical reaction, it is only transformed.

In summary, the law of conservation of matter establishes that matter cannot be created or destroyed (option C).

Answer:

Distillation will be the best method for the separation of solute from the solvent in a solution.

Explanation:

Answer:

Ans : 22.86 gm of Aluminium

Solution,

                        3FeO + 2Al ---> 3 Fe + [tex]Al_{2}O_{3}[/tex]

Given                   3          2                    

Find                    1.27       x

By the given gms of FeO find its mole and put the moles in the find,

                                       [tex]n = \frac{given mass}{molecular mass}[/tex]

                  Given mass of FeO is 91.8

                   Molecular mass of FeO is 71.8

                                         n = [tex]\frac{91.8}{71.8}[/tex]  

                                         n = 1.27 moles of FeO  

Now solve for x,

                            [tex]x = \frac{2 x 1.27}{71.8}[/tex]

                             x = 0.85 moles

These are just moles of Aluminium that we need to react with FeO, so to find Grams of Aluminium we need,

                                Mass = moles x molecular mass

                                Mass = 0.85 x 27(atomic mass of Al)

                                Mass = 22.86 grams of aluminium is what we need

Explanation:

From Beer-Lambert's law;

A=εcl

Where A = absorbance of GMP= 0.2

ε= molar extinction coefficient of GMP = 9000 M-1cm-1

c= concentration of GMP= the unknown

l= path length = 1 cm

c= A/εl = 0.2/ 9000 M-1cm-1 × 1 cm

Answer:

Theoretical yield = 0.1 g

Percent yield = 80%

Explanation:

Given data:

Mass of sodium = 2.3 g

Actual yield of hydrogen = 0.080 g

Theoretical yield = ?

Percent yield = ?

Solution:

Chemical equation:

2Na + 2H₂O    →  H₂ + 2NaOH

Number of moles of sodium:

Number of moles = mass/ molar mass

Number of moles = 2.3 g/ 23 g/mol

Number of moles = 0.1 mol

Now we will compare the moles of sodium with hydrogen to calculate the theoretical yield.

                       Na               :              H₂

                        2                :               1

                     0.1                 :             1/2×0.1 = 0.05 mol

Mass of hydrogen produced:

Mass = number of moles × molar mass

Mass = 0.05 mol × 2 g/mol

Mass = 0.1 g

Percent yield of hydrogen:

Percent yield = actual yield / theoretical yield ×100

Percent yield = 0.08 g/ 0.1 g×100

Percent yield = 0.8×100

Percent yield = 80%

This is because it says Diammonium Hydrogen Phosphate. Here. (NH4)3PO4 is one way to write this. However, another way to write this is (NH4)2HPO4. There should be in fact two ammonium groups, NH4 and 1 Hydrogen to get 3+ charge to balance the 3- charge from the Phosphate.

Answer:

100.5 ≈ 101

Explanation:

Km for S1 = 2.0 mM

Km for S2 = 20 mM

Given that : S1 = S2 =  hence Vmax for either S1 or S2 can represent

The Vmax can be calculated using the data Given and equation below

Vo = Vmax [s] / ( Km + [s] )  ------ (1)

Vo = 0.5

[s] = 0.1 mM

km = 20 mM

making Vmax subject of  equation 1

Vmax = 0.5 ( 20.1 mM) / (0.1 mM )

         = 100.5 ≈ 101

We have to determine its mass.

The density and mass of body are related as follows -

D = M / V

where -

V -  volume of the body.

M - mass of the body.

D - density of the body.

Using the formula discussed above -

D = M / V

M = D x V

M = 2.5 x 4 = 10 g

Answer:

Partial pressure of Gas A = 3.91 atm

Partial pressure of Gas B = 5.10 atm

Partial pressure of Gas C = 5.99 atm

Explanation:

Number of moles of gas A;

n_A = 13.56 g/mol ÷ 6 g = 2.25 moles

Number of moles of gas B;

n_B = 11.76 g/mol ÷ 4 g

n_B = 2.94 moles

Number of moles of gas C;

n_C = 12.07 g/mole ÷ 3.5 moles

n_C = 3.45 moles

Total number of moles = n_A + n_B + n_C = 2.25 + 2.94 + 3.45 = 8.64 moles

Mole fraction of gas A; X_a = 2.25/8.64

Mole fraction of gas B;X_b = 2.94/8.64

Mole fraction of gas C;X_c = 3.45/8.64

Now, partial pressure of each gas will be;

Mole fraction × Total pressure

We are given total pressure of 15 atm.

Thus;

P_a = (2.25/8.64) × 15

P_a = 3.91 atm

P_b = (2.94/8.64) × 15

P_b = 5.10 atm

P_c = (3.45/8.64) × 15

P_c = 5.99 atm

Thus;

Partial pressure of Gas A = 3.91 atm

Partial pressure of Gas B = 5.10 atm

Partial pressure of Gas C = 5.99 atm

Answer:

449 g/L

0.449 g/mL

Explanation:

Step 1: Given data

Step 2: Calculate the density (ρ) of the baseball in g/L

The density is equal to the quotient between the mass and the volume.

ρ = m / V

ρ = 350 g / 0.780 L

ρ =449 g/L

Step 3: Convert ρ from "g/L" to "g/mL"

We will use the conversion factor 1 L = 1000 mL.

449 g/L × (1 L/1000 mL) = 0.449 g/mL

Answer:

The answer is B

Explanation:

Neap tides are a type of to tie occuring after spring tides. It occurs when moon and sun are at the right angles to each other. It produce low tidal ranges. Hence, phrase B is correct.

Tides are a geographical phenomenon taking place due to the gravitational pull by sun and moon on the ocean of earth. They are long period waves causing the ocean back and forth to the cost.

During new moons larger tides appears in earth and they are called spring tides. Spring tides occurs twice in a lunar month. During spring tides, moon appears full and earth is between sun and moon.

After seven days of spring tide, lower tides are produced when the moo and sun comes in right angle to each other. They are called the neap tides producing lower range of tidal waves . During this time moon will be half full thus for the first and last quarter of the moon. Hence, the option B neap tide produce low tidal ranges is correct.
