As AgNO3 dissolves how does the temperature of the solution change

1 answer:

3 0

AGNO3 (s) ----> Ag^+ (aq) + NO3^- (aq) { inorganic reaction }

the dissolution process is endothermic ( absorb energy ) , the crystallization process is exothermic ( release energy )

the temperature will go down and feel cool as the solute dissolves
the rate of crystallization and rate of dissolution will be equal or the same at equilibrium. the rate of dissolution will initially increase , because the process needs to absorb energy to occur , by heating the solution energy is added and the solubility of the solute will decreases more silver nitrate .

How many moles of na2co3 are necessary to reach stoichiometric quantities with cacl2

lbvjy [14]

0.0102 moles Na₂CO₃ = 1.08g of Na₂CO₃ is necessary to reach stoichiometric quantities with cacl2.

<h3>Explanation:</h3>

Based on the reaction

CaCl₂ + Na₂CO₃ → 2NaCl + CaCO₃

1 mole of CaCl₂ reacts per mole of Na₂CO₃

we have to calculate how many moles of CaCl2•2H2O are present in 1.50 g

We must calculate the moles of CaCl2•2H2O using its molar mass (147.0146g/mol) in order to answer this issue.
These moles, which are equal to moles of CaCl2 and moles of Na2CO3, are required to obtain stoichiometric amounts.
Then, we must use the molar mass of Na2CO3 (105.99g/mol) to determine the mass:

<h3>Moles CaCl₂.2H₂O:</h3>

1.50g * (1mol / 147.0146g) = 0.0102 moles CaCl₂.2H₂O = 0.0102moles CaCl₂

Moles Na₂CO₃:

0.0102 moles Na₂CO₃

Mass Na₂CO₃:

0.0102 moles * (105.99g / mol) = 1.08g of Na₂CO₃ are present

Therefore, we can conclude that 0.0102 moles Na₂CO₃ is necessary.to reach stoichiometric quantities with cacl2.

Identify the effect of increasing acidity on the solubility of the given compounds.

Ilia_Sergeevich [38]

All the given compounds are basic on acidifying their solubility increases.

<u>Explanation:</u>

$C a_{3}\left(P O_{4}\right)_{2}$ solubility will increase, since it is basic in nature, on acidifying solubility increases.
$F e S$ being basic on acidification, the solubility increases.
$M g C O_{3}$ is alkaline in nature, it gets neutralized and there is no increase in acidity.
$M g B r_{2}$ is a salt and it shows no effect on acidification.
$A g I$ is a salt but insoluble in water and shows no effect on acidification.
$M g(O H)_{2}$ is strongly basic in nature, on acidifying the solubility increases.
