Answer:
0.84 mol
Explanation:
Given data:
Moles of ZnCl₂ produced = ?
Mass of Zn = 55.0 g
Solution:
Chemical equation:
2HCl + Zn → ZnCl₂ + H₂
Number of moles of Zn:
Number of moles = mass / molar mass
Number of moles = 55.0 g/ 65.38 g/mol
Number of moles = 0.84 mol
Now we will compare the moles of Zn with ZnCl₂ from balance chemical equation.
Zn : ZnCl₂
1 : 1
0.84 : 0.84
So from 55 g of Zn 0.84 moles of zinc chloride will be produced.
Answer:
This is not a balanced equation
Explanation:
Let's make it a balanced equation.
2 NH3 + H2So4 = (NH4)2So4
Glad I could help!!
If CFC increases, there will be a ozone depletion ! the UV rays starts entering and leads to mutation and deaths !
the temperature of the climate increases drastically !
Formula:
0.57 liters = 1 breath(17 breaths = 1minute)(60 minutes = 1 hour)(8 hours) = 4651.2 liters
each breath is 0.57 liters
He or she exhales 17(0.57) = 9.69 liters in a minute
in an hour, he or she exhales 9.69(60) liters in a minute = 581.4 liters
Answer = in 8 hours he or she exhales, 581.4(8) = 4651.2 liters in 8 hours
Hope that answers your question!!!!have a great day!!!
