Because that solid is frozen liquid, so when it gets heated up, it will melt. Like Ice.

Hope I Helped! :)

Answer: 0.0285 moles of HCl is present in given amount of solution.

Explanation:

Molarity is defined as the amount of solute expressed in the number of moles present per liter of solution. The units of molarity are mol/L. The formula used to calculate molarity:

$\text{Molarity of solution}=\frac{\text{Moles of solute}\times 1000}{\text{Volume of solution (mL)}}$ .....(1)

Given values:

Molarity of HCl = 0.453 M

Volume of solution = 62.85 mL

Putting values in equation 1, we get:

$0.453mol/L=\frac{\text{Moles of HCl}\times 1000}{62.85}\\\\\text{Moles of HCl}=\frac{0.453\times 62.85}{1000}=0.0285moles$

Hence, 0.0285 moles of HCl is present in given amount of solution.

Tomtit [17]

Chemical equation:

Pb(NO3)2(aq) + 2NH4I(aq) -->PbI2(s) + 2NH4NO3(aq)

Precipitate:

PbI2 (because it's a yellow insoluble solid)

Complete Ionic Equation:

Pb(aq) + 2NO3(aq) + 2NH4(aq) + I2(aq) --> Pb(s) + I2(s) + 2NH4(aq) + 2NO3(aq)

Net ionic equation:

Pb(aq) + I2(aq) --> Pb(s) + I2(s)

Let me know if there are any errors. Goodluck :)
