vampirchik [111]

Answer:

C) As a gas is heated, the pressure decreases.

Explanation:

From the choices given, the statement that "as a gas is heated, the pressure decreases is false".

When gases are heated, their molecules expands and the volume of the gas increases. In a fixed container, the pressure of the gases will also increases.

  • Gases lack internal cohesion and very weak to no intermolecular forces binding them together.
  • When they are subjected to heat, they gain more energy(kinetic energy) which causes them to begin to spread out.
  • Thus, they take up even more space allowing volume to increase appreciably.

Which of the chemical equations is balanced?
Simora [160]

The third equation is properly balanced.

To figure this out, set up tables to check if each element has the same amount on both sides. If you do this for the third equation, copper, hydrogen, oxygen, and nitrogen are all balanced,

The first equation is incorrect due to the fact Iron, Fe, is not balanced on both sides. This is shown by the subscripts given.

The second equation is incorrect as Sulfur is not properly balanced and neither is sodium.

The fourth equation is incorrect as Aluminum is not properly balanced. On the reactants side, Aluminum is 4 while on the products, Aluminum is 8.

Hope this helps!
