Supposing complete ionization: 
<span>CaCl2 → Ca{2+} + 2 Cl{-} [three ions total] </span>

<span>(1.56 m CaCl2) x (3 mol ions / 1 mol CaCl2) = 4.68 m ions </span>

<span>(1.86 °C/m) x (4.68 m) = 8.70 °C change </span>

<span>0°C - 8.70°C = - 8.70°C</span>

HELP Consider this equation...
Mashcka [7]

Answer:

it is not correct I have an answer for ''why''

Explanation:

You need to balance it

s= 2

0=2

S+30•2 --------> SO•3

2 2 2 2

S +3O•2-------->SO•2......MULTIPLY

2 4 2 4......LCM IS 4

2 1 2 1....DIVIDE BY 4

SO NOW WE GOT THE BALANCE NO. WE CAN PUT IT IN THE EQUATIONS.

2S+3O•2 -----> 2SO•3

now you can check the both sides its balances the correct answer is this

Calculate the number of miles of magnesium,chlorine, and oxygen atoms in 5.00 moles of magnesium perchlorate
Zigmanuir [339]

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
