Determine the volume at STP of 36.8 g of nitrogen dioxide (NO2)

Chemistry

17.92L

Explanation:

Given parameters:

Mass of NO₂ = 36.8g

Condition = STP

Unknown:

Volume of gas = ?

Solution:

The volume of gas can be determined at STP if the number of moles of that gas is known.

    Volume of NO₂ at STP = number of moles x 22.4

 Number of moles = \frac{mass}{molar mass}

Molar mass of NO₂ = 14 + 2(16) = 46g/mol

  Number of moles = \frac{36.8}{46} = 0.8mole

 Now;

 Volume of NO₂ = 0.8 x 22.4 = 17.92L

How can equilibrium of a closed system chemical reaction be disturbed? Select all that apply.
charle [14.2K]

The correct answers are :

Changing the volume of the system.

Changing the temperature of the system.

Equilibrium will remain unaffected if the concentration of products and reactants are kept the same, and the temperature of the system is kept constant.

As the system is closed, we cannot add or remove products or reactants.

Change in temperature will shift the chemical equilibrium towards the reactant or product depending on whether the reaction is exothermic or endothermic.

Also change in volume  will shift the chemical equilibrium of a chemical reaction if the reactants or products or both are gases.

According to the law of conservation of mass, the amount of BARIUM present of the reactants is the same as the amount present in the products (the precipitate). 

(11.21 g BaSO4) / (233.4 g/mol BaSO4) = 0.0480 mol BaSO4 and original barium salt 

(10.0 g) / (0.0480 mol) = 208.3 g/mol 

So it must have been BaCl2, because the molar mass of Barium is 137 which leave 71 grams left. Since Barium is a +2 charge, it means the atom next to it must be twice. Chlorine mass is 35, which twice is 71
