Answer: -
Sulfuric acid
Explanation: -
The chemical formula of Sulfuric Acid = H₂SO₄
The chemical formula of hydrochloric acid = HCl
In both the cases the concentration of the acid is same.
However from the chemical formula of sulfuric acid we can see that it is a dibasic acid.
So for every mole of sulfuric acid 2 mol of H⁺ would be present.
The above experiment is a type of simple displacement reaction. Thus Mg displaces H⁺ from H₂SO₄ in the above experiment.
Thus if more H⁺ is present, more of Mg reacts in the same amount of time.
Hence the reaction would be faster in sulfuric acid at the start.

Answer: ![2LiOH+CO_2\rightarrow Li_2CO_3+H_2O](https://tex.z-dn.net/?f=2LiOH%2BCO_2%5Crightarrow%20Li_2CO_3%2BH_2O)
Explanation:
When LiOH and carbon dioxide reacts , they form lithium carbonate and water.
The skeletal equation will be:
![LiOH+CO_2\rightarrow Li_2CO_3+H_2O](https://tex.z-dn.net/?f=LiOH%2BCO_2%5Crightarrow%20Li_2CO_3%2BH_2O)
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
The balanced equation will be:
![2LiOH+CO_2\rightarrow Li_2CO_3+H_2O](https://tex.z-dn.net/?f=2LiOH%2BCO_2%5Crightarrow%20Li_2CO_3%2BH_2O)
Matter is anything that takes up space and has mass. Taking up space means that an object has a measurable volume. Mass indicates how much force is required to move the object. Variations of matter include classical matter and dark matter.
