Answer:
<h3>The answer is 0.1 mol</h3>Explanation:
To find out the number of moles we use the formula
where
n is the number of moles
M is the molar mass
m is the mass of the substance
From the question
m = 400 g
M of Ca = 40 g/mol
We have
We have the final answer as
<h3>0.1 mol</h3>Hope this helps you
Explanation:
(a)
This is acid base reaction because there is no change of oxidation state on either side of the reaction.
(b)
This is a oxidation reduction reaction because sodium in elemental state ( 0 oxidation state) oxidizes to Na⁺ in NaCl. Also H⁺ in HCl reduces to H° in H₂.
(c)
This is a oxidation reduction reaction because magnesium in elemental state ( 0 oxidation state) oxidizes to Mg²⁺ in MgCl₂. Also Cl° in Cl₂ reduces to Cl⁻ in MgCl₂.
(d)
This is acid base reaction because there is no change of oxidation state on either side of the reaction.
(e)
This is a oxidation reduction reaction because phosphorous in P³⁻ in K₃P oxidizes to P⁵⁺ in K₃PO₄ and oxygen reduces.
(f)
This is acid base reaction because there is no change of oxidation state on either side of the reaction.
