Answer:
Explanation:
Hello,
In this case, by means of the law of mass action, we firstly write the described chemical reaction:
Thus, as ammonia is being formed at 0.345 M/s, nitrogen will be disappearing at (consider law of mass action):
Best regards.

Answer:
i think it is d Glass cell
Explanation:
Answer is: It can be reshaped by a force.
Physical property can be observed and measured without any changes in molecular composition. The same substance is present before and after the change, changing the shape is physical change.
Copper reaction with acid, ignition and combination with oxygen are chemical change (chemical reaction), because new substances are formed, the atoms are rearranged and the reaction is followed by an energy change.
Answer:
Hydrogen
Explanation:
A reducing agent is a substance which gives up its electrons to become oxidized. Generally, metals are oxidized (reducing agents) while non-metals are reduced (oxidizing agents).
However, hydrogen which is a non-metal is usually oxidized in the presence of stronger oxidizing non-metals such as fluorine and oxygen.
Hydrogen thus, acts as a reducing agent by giving up its electrons to become oxidized. Even though among all non-metals, Hydrogen has the greatest potential to be oxidized, it is a poor reducing agent compared to reactive metals.
