True. Water acts as a solvent as the solute dissolves into water.
When MgO and H2O react they form Magnesium Hydroxide Mg(OH)2
It's very easy, it's depending mainly on converting a mathematical unit:
When 1 Cm = 0.0328084 Ft
So, we assume that:
in 1 year → it grows 3.38 Ft
So X(years)→ 0.0328084
∴X(years) = 0.0328084 * 3.38 = 0.0097 year
We have to convert this unit form years to days by:
1 year = 365 days
So, 0.0097 = X (days)
∴X(days)= 365 * 0.0097 = 3.5 days
So it will take 3.5 days to grow up
Answer:
The balanced equation is :
Zn(s) + H2SO4(aq) → ZnSO4(aq) + H2(g)
