Answer:
60 mL
Explanation:
200 mL = 0.2 L
We know that:
Molarity = Moles / Liters
So:
4.20 M = moles / 0.2 L
moles = 4.20 x 0.2 = 0.84
Then:
14.0 M = 0.84 moles / Liters
Liters = 0.84 moles / 14.0 M = 0.06 L
Since they want the answer in mL, convert 0.06 to get 60 mL
Answer:
53.491 g/mol
Explanation:
Create the chemical compound and find each individual element's molar mass. Lastly, add them up.
I think it’s C since the ice changes from solid to a liquid which is physical and then it reacts with calcium metal making the calcium hydroxide which is chemical change. And another sign of it being chemical was the release of gas.
Water b/c it is insoluble in water. it is soluble in cyclohexane and sparingly <span>soluble in ethyl alcohol.
