2 ways to do this
a. find %Cl in CaCl2
2 x 35.45g/mole = 70.9g Cl
70.9g Cl / 110.9g/mole CaCl2 = 63.93% Cl in CaCl2
0.6963 x 145g = 92.7g = mass Cl
b. determine moles CaCl2 present then mass Cl
145g / 110.9g/mole = 1.31moles CaCl2 present
2moles Cl / 1mole CaCl2 x 1.31moles = 2.62moles Cl
2.62moles Cl x 35.45g/mole = 92.7g Cl
Igneous <span>rock ! Of course oh how i miss middle school.........</span>
Gas x would be carbon dioxide.
note/ acid + carbonate —> salt + water + carbon dioxide
the white precipitate would be calcium carbonate. CaCo₃
note/ this is a common eqn u need to remember.
X - CO₂ (carbón dioxide)
Y - CaCo₃ (calcium carbonate)
sodium carbonate is a basic salt
Answer:
E and B
Explanation:
the warmer the weather the faster it will decompose, this why is why sometimes bodies last longer frozen, or in cool temperatures.
that statement takes a out.
An illness shouldn't effect a decomposing body
Weight also shouldn't effect a decomposing body
Being buried can make bodies decompose fast because of all the bugs and other animals that will get down there and decompose it faster
Answer: B,E
