the first one is <u>A covalent bond.</u>
the second one is Answer: <u>B Decomposition</u>
<span>The answer is to contain salt in low conecentrations. Fresh water can only be considered fresh water, if and only if it contains less than 0.5 parts per thousands of salt in the water. Fresh water do contains salt, but it is in lower concentrations than salt water.</span>
Medium about 3 second? Not sure lol just need more points honestly lol
Moles of Lithium phosphate : 0.495
<h3>Further explanation</h3>
Given
6 Li + Zn₃(PO₄)₂ ------- > 2 Li₃PO₄ + 3 Zn
Required
Moles of Lithium phosphate
Solution
moles of Zinc(Ar=65,38 g/mol) :
= mass : Ar
= 48.6 : 65.38
= 0.743
From equation, mol ratio of Zn : Li₃PO₄ = 3 : 2, so mol Li₃PO₄ :
= 2/3 x mol Zn
= 2/3 x 0.743
= 0.495
