Answer:
What are the statements please
Explanation:
Answer:
Sand (SiO2 silica) In its pure form it exists as a polymer, (SiO2)n.
Soda ash (sodium carbonate Na2CO3) ...
Limestone (calcium carbonate or CaCo3) or dolomite (MgCO3)
Explanation:
I am pretty sure you know what sand is, Soda ash is a fine white colored powder that is extracted from the ashes of plants growing in sodium rich soils. Limestone is is a common type of carbonate sedimentary rock.

Answer: The balanced equation is
.
Explanation:
The given reaction equation is as follows.

Number of atoms present on reactant side are as follows.
- Li = 1
- H = 1
= 1
Number of atoms present on product side are as follows.
- Li = 1
- H = 2
= 1
To balance this equation, multiply Li by 2 and
by 2 on reactant side. Also, multiply
by 2 on product side.
Hence, the equation can be rewritten as follows.

Now, number of atoms present on reactant side are as follows.
- Li = 2
- H = 2
= 2
Number of atoms present on product side are as follows.
- Li = 2
- H = 2
= 2
As there are same number of atoms on both reactant and product side. Hence, the equation is now balanced.
Thus, we can conclude that the balanced equation is
.
