Answer:
When an acid reacts with a metal, what is one of the usual products?
<u><em>C) Hydrogen gas</em></u>
Explanation:
Answer: (B) The reverse reaction will proceed to establish equilibrium.
Explanation:
Any change in the equilibrium is studied on the basis of Le-Chatelier's principle.
This principle states that if there is any change in the variables of the reaction, the equilibrium will shift in the direction to minimize the effect.
For the given equation:
Given : when
is added to the system
If the concentration of
that is the product is increased, so according to the Le-Chatlier's principle, the equilibrium will shift in the direction where decrease of concentration of
takes place. Therefore, the equilibrium will shift in the left or backward direction.
Thus the reaction will shift towards reactants to reestablish equilibrium and thus partial pressure of
and
decreases and the partial pressure of
increases.
Find the density of the plastic. if the density is less than that of water, it's going to float. If it's more than the density of water, then it's going to sink.
