Answer:
ClO- = bronsted Lowry base
H2PO4- =Bronsted Lowry base
Explanation:
ClO- = is bronsted Lowry base because it accepts a proton in the reaction
H2PO4- =Bronsted Lowry base because it's a proton donor in the reaction
4 moles of water will have 4 number of water molecules
Excess reactant : Na
NaCl produced : = 16.497 g
<h3>Further explanation</h3>
Given
Reaction(balanced)
2Na + Cl₂⇒ 2NaCl
20 g Na
10 g Cl₂
Required
Excess reactant
NaCl produced
Solution
mol Na(Ar = 23 g/mol) :
= 20 : 23 = 0.87
mol Cl₂(MW=71 g/mol):
= 10 : 71 g/mol = 0.141
mol : coefficient :
Na = 0.87 : 2 = 0.435
Cl₂ = 0.141 : 1 = 0.141
Limiting reactant : Cl₂(smaller ratio)
Excess reactant : Na
Mol NaCl based on mol Cl₂, so mol NaCl :
= 2/1 x mol Cl₂
= 2/1 x 0.141
= 0.282
Mass NaCl :
= 0.282 x 58.5 g/mol
= 16.497 g
The substance will not sink in water, as it Dencity is (0.5)is less than the density of water (1gcm).
