Answer:
Remain unchanged.
Explanation:
The total number of moles of liquid remain unchanged as the some moles of species B are added to the system because specie B that is added in the liquid phase is again restored after addition. If the specie B did not restored after addition to the liquid phase so the total number of moles increases in the liquid phase so that's why we can say that the liquid phase remain unchanged.
Answer:
Ba(OH)2(aq)+H2SO4(aq) gives us 2BaH+H2O
Explanation:
Answer:
The reactants and products in a chemical reaction contain the same atoms, but they are rearranged during the reaction. As a result, the atoms end up in different combinations in the products. This makes the products new substances that are chemically different from the reactants.
Explanation:
Answer:
5 atoms
Explanation:
When a chemical reaction starts with 5 atoms of hydrogen, and the reaction goes into completion, it must give us 5 atoms of hydrogen.
This is in compliance with the law of conservation of mass which states that "in a chemical reaction, matter is neither created nor destroyed but converted from one form to another".
In chemical reactions, bonds are broken and new compounds are formed in the process. The same number of species at the start and end of the reaction must still be the same.
