A certain amount of gas is trapped in a nonrigid container at atmospheric pressure. If the container is cooled and the gas in th
Akimi4 [234]

Answer:

D. The volume of the container will decrease.

Explanation:

  • We apply here, the general gas law of ideal gases:

<em>PV = nRT,</em>

where, P is the pressure of the gas.

V is the volume of the container.

n is the no. of moles of the gas.

R is the general gas constant.

T is the temperature of the gas.

  • We are given that P is constant.

Also, n is constant as there is no added external gases.

T is decreased as the container is cooled.

So, the volume will change as the container is nonrigid.

<em>V α T.</em>

The volume is directly proportional to the temperature,

<em>Thus, as the container is cooled, the T will decrease, and the volume of the container will decrease.</em>

Balance the chemical equation. ___Mg + ___Fe2O^3 -&gt; ___MgO + ___Fe
VMariaS [17]

Answer:

3Mg + Fe₂O₃ → 3MgO + 2Fe.

Explanation:

  • To balance the equation, you should apply the law of conservation of mass for the equations.
  • The law of conservation of mass states that the no. of each atom is equal in both sides (reactants and products).
  • The balanced equation is:

<em>3Mg + Fe₂O₃ → 3MgO + 2Fe.</em>

<em></em>

That 3.0 mole of Mg react with 1.0 mole of Fe₂O₃ to produce 3.0 moles of MgO and 2.0 moles of Fe.

  • The no. of all atoms is the same in both of reactants and products side.

Mg (3), Fe (2), and O (3).
