Answer : The net ionic equation will be,
Explanation :
In the net ionic equations, we are not include the spectator ions in the equations.
Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.
The balanced ionic equation between zinc and hydrochloric acid will be,
The ionic equation in separated aqueous solution will be,
In this equation, 
is the spectator ion.
By removing the spectator ion from the balanced ionic equation, we get the net ionic equation.
The net ionic equation will be,
Answer:
Explanation:
<u><em>Given :</em></u>
Mass in grams = m = 42 g
Molar Mass = M = 12
<u><em>Required:</em></u>
No. of moles = n = ?
<u><em>Formula :</em></u>
m = m / M
<u><em>Solution:</em></u>
n = 42 / 12
n = 3.5 moles
The reaction that results from this is:
H2O + CO2 --> H2CO3
Stoichiometric ratio between water and CO2 is 1:1. So we can say that for every Mole of CO2, we need 1 Mole of water to produce 1 Mole of H2CO3. Thus as n=m/M we can find n = 528/44.01 = 11.997 ~ 12Mol.
therefore, we need 12 moles of water.

Answer:- Specific gravity of glucose solution is 1.02.
Solution:- Specific gravity is the ratio of the compound density with water density, means how denser the compound solution is as compared to water.
specific gravity = 
density of glucose is given as 1.02 g per mL and water density is 1.00 g per mL.
Let's plug in the values in the formula:
specific gravity = 
= 1.02
So, the specific gravity of glucose is 1.02. It indicates that glucose is 1.02 times more denser than water.
