As per the given chemical equation, 1 mole of Cl₂ is formed when 87.9 kJ of heat is absorbed.

Therefore, 250.0 kJ of heat will yield

\frac{1 mol Cl2}{87.9 kJ } \\ x 250.0 kJ = 2.84 mol Cl₂

Molar mass of mol Cl₂ = 71 g /mol

Mass of Cl₂ =2.84 mol Cl₂ x 71 g /mol = 201.64 g

201.64 g of Cl₂ will be produced along with 250.0 kJ of heat in the given reaction.

What is the molarity of a solution that contains 4.3 mol of acetic acid (C2H3O2) in 450. mL of solution?

lord [1]

Hey there !

Number of moles of solution: 4.3 moles

Volume in liters:

450.0 mL / 1000 => 0.45 L

Therefore:

Molarity = number of moles / volume of solution ( L)

Molarity = 4.3 / 0.45

=> 9.55 M

Hope that helps!

Infer if the mineral Talc would be a good choice when building a statue outside?

ruslelena [56]

Talc is not a good choice when building a statue because the mineral Talc is one of the weakest minerals on the Mohs Scale with a hardness of 1 since it could be scratched by a fingernail, which means that when people build a statue with Talc, it could be easily broken down.
