A container of gas has a volume of 3.5 L and a pressure of 0.8 atm. Assuming the temperature remains constant, what volume of ga
vovikov84 [41]
<h3>Answer:</h3>

5.6 L

<h3>Explanation:</h3>

We are given;

  • Initial volume, V1 = 3.5 L
  • Initial pressure, P1 = 0.8 atm
  • Final pressure, P2 = 0.5 atm

We are required to calculate the final volume;

  • According to Boyle's law, the volume of a fixed mass of a gas and the pressure are inversely proportional at a constant temperature.
  • That is; P α 1/V
  • Mathematically, P=k/V
  • At two different pressure and volume;

           P1V1 = P2V2

In this case;

Rearranging the formula;

V2 = P1V1 ÷ P2

     = (0.8 atm × 3.5 L) ÷ 0.5 atm

    = 5.6 L

Therefore, the resulting volume is 5.6 L

What is Haber's process? Write it with chemical reaction.​
Lana71 [14]

Answer: Habers process is the industrial process used for the production of ammonia

N_2(g)+3H_2(g)\rightarrow 2NH_3(g)

Explanation:

Habers process is the industrial process used for the production of ammonia. It uses hydrogen from natural gas and nitrogen mainly from atmosphere under extremely high pressures (150-200atm) and moderately high temperatures (400-450^0C).

The catalyst used in Habers process is iron.

The balanced chemical reaction is:

N_2(g)+3H_2(g)\rightarrow 2NH_3(g)

What is the molality of an aqueous KCl solution with a mole fraction of KCl, XKCl = 0.175? (The molar mass of KCl = 74.55 g/mol
NARA [144]

Answer:

The molality of the KCl solution is 11.8 molal

Explanation:

Step 1: Data given

Mol fracrion KCl = 0.175

Molar mass KCl = 74.55 g/mol

Molar mass H2O = 18.02 g/mol

Step 2: Calculate mol fraction H2O

mol fraction H2O = 1 - 0.175 = 0.825

Step 3: Calulate mass of H2O

Suppose the total moles = 1.0 mol

Mass H2O = moles H2O * molar mass

Mass H2O = 0.825 * 18.02 g/mol

Mass H2O = 14.87 grams = 0.01487 kg

Step 4: Calculate molality

Molality KCl = 0.175 / 0.01487 kg

Molality KCl = 11.8 molal

The molality of the KCl solution is 11.8 molal

16. Formaldhyde has a mole ratio of 1 mole C: 2 moles H: 1 mole O. Its empirical formula is the same as its
Dominik [7]

Answer:

d. 97.60 g

Explanation:

Given parameters:

Number of moles of formaldehyde = 3.25moles

  Ratio:

                 C               H              O

                  1                2               1

Unknown:

Mass of this sample  = ?

Solution:

The empirical formula of a compound is its simplest formula. It is the simplest whole number ratio of the atoms in a given substance.

The molecular formula is the actual formula of the compound.

 Since the molecular and empirical formula are the same here, the formula of the compound is;

                   CH₂O

To find the mass of the formaldehyde, use the expression below;

        Mass  = number of moles x molar mass

             molar mass of CH₂O = 12 + 2(1) + 16  = 30g/mol

      Mass  = 3.25 x 30  = 97.5g
