Answer:

Atoms are the building blocks of matter. They are the smallest particles of an element that still have the element's properties. All atoms are very small, but atoms of different elements vary in size. Three main types of particles that make up all atoms are protons, neutrons, and electrons.

Can 1750 mL of water dissolve 4.6 moles of Copper Sulfate CuSO4? _________ Why? / Why not?
Wewaii [24]

Answer:

  • <u>No, you cannot dissolve 4.6 moles of copper sulfate, CuSO₄, in 1750mL of water.</u>

Explanation:

This question is part of a Post-Lab exercise sheet.

Such sheet include the saturation concentrations for several salts.

The saturation concentration of Copper Sulfate, CuSO₄, indicated in the table is 1.380M.

That means that 1.380 moles of copper sulfate is the maximum amount that can be dissolved in one liter of solution.

Find the molar concentration for 4.6 moles of copper sulfate in 1,750 mL of water.

You need to assume that the volume of water (1750mL) is the volume of the solution. This is, that the 4.6 moles of copper sulfate have a negligible volume.

<u>1. Volume in liters:</u>

  • V = 1,750 mL × 1 liter / 1,000 mL = 1.75 liter

<u />

<u>2. Molar concentration, molarity, M:</u>

  • M = number of moles of solute / volume of solution in liters

  • M = 4.6 moles / 1.75 liter = 2.6 M

Since the solution is saturated at 1.380M, you cannot reach the 2.6M concentration, meaning that you cannot dissolve 4.6 moles of copper sulfate, CuSO₄ in 1750mL of water.

Gnesinka [82]

Answer: 5 moles of  H_2CO_3 can be produced from 5 mol NaHCO3 and 9 mol HCl.

Explanation:

The balanced chemical reaction is:

NaHCO_3+HCl\rightarrow H_2CO_3+NaCl

According to stoichiometry :

1 mole of NaHCO_3 use 1 mole of HCl

Thus 5 moles of NaHCO_3 use=\frac{1}{1}\times 5=5moles  of HCl

Thus NaHCO_3 is the limiting reagent as it limits the formation of product and HCl is the excess reagent.

As 1 mole of NaHCO_3 give = 1 mole of H_2CO_3

Thus 5 moles of NaHCO_3 give =\frac{1}{1}\times 5=5moles  of H_2CO_3

5 moles of  H_2CO_3 can be produced from 5 mol NaHCO_3 and 9 mol HCl.
