Answer:
24.5%
Explanation:
You just add up the atomic masses.
Ca - 40.078
Cl2 - 35.4527 x 2 = 70.9054
------ 110.9834
H4 - 1.00794 x 4 = 4.03176
O2 - 31.9998
------ 36.03056
TOTAL - 147.01396
So the water is 36.03056/147.01396 = .245082576 but that is only accurate to three decimals (because the mass of Ca was only given to three decimals) so we write .245 and that is 24.5%
This is not my answer but I found it on Yahoo answers and it was answered by Anonymous.
Answer:
B. Cell Type
Explanation:
that is the answer i believe
Explanation:
Monitor the temperature of the water with the thermometer. Stop heating the water once it nears the boiling point of 100 degrees Celsius. Add copper(II) sulfate and stir until the heated solution is saturated. When the solution is saturated, copper(II) sulfate will not dissolve anymore
1. She would want a balanced force so she doesn't fall but, well, keep her balance.
2. Frictional force because when an object slows down it's because a higher amount of friction is acting on it.
3. It would be magnitude and direction because is like the size of the object and they need to know how much force it will take to move it.
4. Is the same as 3...
5. A push and a pull are a force.
I hope this helps!
