Answer:
I'm sry I was trying to figure it out but it makes no sense I'm really sorry
Answer:
21.3 g of CaCl₂ are produced in this reaction
Explanation:
Reaction is this:
CaCO₃ + 2HCl → CaCl₂ + H₂CO₃
Molar mass salt : 100.08 g/m
Molar mass acid: 36.45 g/m
We have 28 g / 100.08 g/m = 0.279 moles of CaCO₃
We have 14 g / 36.45 g/m = 0.384 moles of HCl
Ratio is 1:2, so 0.279 moles of salt will need the double of moles of acid.
0.279 . 2 = 0.558 moles of acid needed. (I have only 0.384 moles, so the acid is the limiting reactant)
0.384 moles of HCl produce the half of moles of CaCl₂ (This ratio is 1:2) --> 0.192 moles
Molar mass of CaCl₂ = 110.98 g/m
Mol . molar mass = mass → 0.192 m . 110.98 g/m = 21.3 g
Answer:
Mass movement, or mass wasting, has significant effects on humans, including loss of property, severe injury and death.
Explanation:
There's 34 quarters in 85 dimes.
If you divide 10 by 2 you get 5, every 2 quarters is 5 dimes.
