Answer: The concentration, in moles per litre, of a solution formed when 13.0 g of calcium hydroxide is dissolved in 5.0 L is 0.036 M
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.
where,
n = moles of solute
= volume of solution in L
moles of 
= 
Now put all the given values in the formula of molality, we get
Therefore, the concentration, in moles per litre, of a solution formed when 13.0 g of calcium hydroxide is dissolved in 5.0 L is 0.036 M
The full ionic chemical balanced equation for CuCl2 and (NH4)2SO4 is 2(NH4)Cl + CuSO4.
Explanation:
The full ionic chemical balanced equation for CuCl2 and (NH4)2SO4 is
CuCl2 + (NH4)2SO4 ⇔ 2(NH4)Cl + CuSO4.
Here the left side one's are reactants i.e.,CuCl2 and (NH4)2SO4.
The right siders are products i.e.,(NH4)Cl and CuSO4.
The complete ionic equation is used to include both chemical species as well as spectator ions. It is used to indicate which of the reactants and products in the equation exists primarily as ions in aqueous solution.
It is nothing but a chemical equation in which electrolytes which are soluble in water are formed as dissociated ions.
The above chemical reaction is double displacement reaction.
<span>2 CH3OH + 3 O2 = 2 CO2 + 4 H2O
2 moles CH3OH ---------------- 3 moles O2
1.33 moles CH3OH ----------- ( moles O2)
moles O2 = 1.33 x 3 / 2
moles O2 = 3.99 / 2
= 1.995 moles of O2</span>
