the answer would be B an atom that has lost an electron
Answer:
0.55mL of carbon tetrachloride
Explanation:
CH4(g) + 2Cl2(g) -------> CCl4(g) + 2H2(g)
From the balanced reaction equation
44800mL of chlorine produces 22400 ml of carbon tetrachloride
If 1.1mL of chlorine were consumed, volume of carbon tetrachloride= 1.1×22400/44800
=0.55mL of carbon tetrachloride
Note: 1 mole of a gas occupies 22.4L volume or 22400mL
Physical isn't so chemical
Mass number of an element write in bottom of it!
So, there 80 would be the mass number of ₈₀Br.
Hope this helps!
16(2)/74.1=.431
.431x100= 43.1%
