Answer:

5.00 mol Mg

10.0 mol Cl

40.0 mol O

Explanation:

Step 1: Given data

Moles of Mg(ClO₄)₂: 5.00 mol

Step 2: Calculate the number of moles of Mg

The molar ratio of Mg(ClO₄)₂ to Mg is 1:1.

5.00 mol Mg(ClO₄)₂ × 1 mol Mg/1 mol Mg(ClO₄)₂ = 5.00 mol Mg

Step 3: Calculate the number of moles of Cl

The molar ratio of Mg(ClO₄)₂ to Cl is 1:2.

5.00 mol Mg(ClO₄)₂ × 2 mol Cl/1 mol Mg(ClO₄)₂ = 10.0 mol Cl

Step 4: Calculate the number of moles of O

The molar ratio of Mg(ClO₄)₂ to Cl is 1:8.

5.00 mol Mg(ClO₄)₂ × 8 mol O/1 mol Mg(ClO₄)₂ = 40.0 mol O

Be sure to answer all parts. For an aqueous solution of sodium chloride (NaCl), determine the molarity of 4.05 L of a solution t

SpyIntel [72]

Answer:

$0.824\ \text{M}$

$5.62\ \text{L}$

$20.89\ \text{mol}$

Explanation:

Molar mass of NaCl = 58.44 g/mol

Mass of NaCl = 195 g

Volume of solution = 4.05 L

Molarity of solution is

$\dfrac{195}{4.05}\times \dfrac{1}{58.44}=0.824\ \text{M}$

The molarity of the solution is $0.824\ \text{M}$

Moles of NaCl = 4.63 mol

Volume is given by

$\dfrac{4.63}{0.824}=5.62\ \text{L}$

The volume of the solution that contains the required amount NaCl is $5.62\ \text{L}$

Volume of solution = $25.35\ \text{L}$

Moles of solution is given by

$0.824\times 25.35=20.89\ \text{mol}$

The number of moles of NaCl is $20.89\ \text{mol}$ .

What determines the types of chemical reactions that an atom participates in? A. the number of electrons in the outermost electr

Dafna1 [17]

Answer:

The answer would be A. the number of electrons in the outermost electron shell.

Explanation:

These are called valence electrons which are transferred, shared, and rearranged by creating covalent bonds producing new substances.

Hope this helped! :)
