Answer: 1 molecule of
reacts with 1 molecule of
to give 2 molecules of HCl.
1 mole of
reacts with 1 mole of
to give 2 moles of HCl.
Explanation:
The given balanced reaction is:
![H_2(g)+Cl_2(g)\rightarrow 2HCl(g)](https://tex.z-dn.net/?f=H_2%28g%29%2BCl_2%28g%29%5Crightarrow%202HCl%28g%29)
On the particulate level :
1 molecule of
reacts with 1 molecule of
to give 2 molecules of HCl.
On molar level:
1 mole of
reacts with 1 mole of
to give 2 moles of HCl.
Iodine react with nitric acid to produce iodic acid, nitrogen dioxide and water.
Answer:
I think it might be a closed system
Answer: a precipitate.
Justification:
When two liquids are mixed together, their constituents may react chemically, forming new products whose chemical properties are different from those of the original constituents of the mixtures.
Then, some of the products formed may be insoluble in the mix. In this case is when the precipitate (solid that cannot stand in the solution) will get formed.
The formation of a precipitate is a clear signal that a chemical reaction has taken place between some constituents (elements or compounds) of the mix.
One example of this situation is the combination of a solution of baking soda, NaHCO₃(aq), and a solution of calcium chloride, CaCl₂ (aq).
Those two solutions are clear, and when combined will form a solid (precipitate) which is calcium carbonate, CaCO₃ (s). The calcium carbonate precipitates because it is not soluble in the mix.
