H requires 1 electron to achieve duplet/2 stability
The H atom must share 1 electron to form a single covalent bond.
Answer:
The mass of NaHCO3 required is 235.22 g
Explanation:
*******
Continuation of Question:
2NaHCO3(s) + H2SO4(aq) → Na2SO4(aq) + 2CO2(g) + 2H2O(l)
You estimate that your acid spill contains about 1.4 mol H2SO4. What mass of NaHCO3 do you need to neutralize the acid?
********\
The question requires us to calculate the mass of NaHCO3 to neutralize the acid.
From the balanced chemical equation;
1 mol of H2SO4 requires 2 mol of NaHCO3
1.4 would require x?
Upon solving for x we have;
x = 1.4 * 2 = 2.8 mol of NaHCO3
The relationship between mass and number of moles is given as;
Mass = Number of moles * Molar mass
Mass = 2.8 mol * 84.007 g/mol
Mass = 235.22 g

Explanation:
One of the ways of driving a reaction towards the forward direction is the removal of one of the products. This will shift the equilibrum towards the right hand side.
Hence, by distilling one of the products from the system, the equilibrum was shifted towards the right hand side and a high percentage of product is obtained.
