Answer : Yes, the given reaction is the complete balanced equation.

Explanation :

Balanced equation : It is defined as the number of individual atoms of an element present on the reactant side always be equal to the number of individual atoms of an element present on product side. That means the complete balanced equation are those which follows the law of conservation of mass.

When aluminum phosphate reacts with magnesium chloride in an aqueous solution then it gives magnesium phosphate and aluminium chloride as a product.

The complete balanced equation will be,

$2AlPO_4(aq)+3MgCl_2(aq)\rightarrow Mg_3(PO_4)_2(s)+2AlCl_3(aq)$

By the stoichiometry, 2 moles of aluminium phosphate react with 3 moles of magnesium chloride to give 1 mole of magnesium phosphate and 2 moles of aluminium chloride.

a concentration solution of H2so4 is 59.4% by mass (m/m) and has a density of 1.83 g/mL. How many mL of the solution would be re

Blababa [14]

Answer: 41.5 mL

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

$Molarity=\frac{n}{V_s}$

where,

n = moles of solute

$V_s$ = volume of solution in L

Given : 59.4 g of $H_2SO_4$ in 100 g of solution

moles of $H_2SO_4=\frac{\text {given mass}}{\text {molar mass}}=\frac{59.4g}{98g/mol}=0.61$

Volume of solution = $\frac{\text {mass of solution}}{\text {density of solution}}=\frac{100g}{1.83g/ml}=54.6ml$

Now put all the given values in the formula of molality, we get

$Molality=\frac{0.61\times 1000}{54.6ml}=11.2M$

To calculate the volume of acid, we use the equation given by neutralisation reaction:

$M_1V_1=M_2V_2$

where,

$M_1\text{ and }V_1$ are the molarity and volume of stock acid which is $H_2SO_4$

$M_2\text{ and }V_2$ are the molarity and volume of dilute acid which is $H_2SO_4$

We are given:

$M_1=11.2M\\V_1=mL\\M_2=0.30M\\V_2=1550mL$

Putting values in above equation, we get:

$11.2\times V_1=0.30\times 1550\\\\V_1=41.5mL$

Thus 41.5 mL of the solution would be required to prepare 1550 mL of a .30M solution of the acid
