Answer:
true
Explanation:
in order for the atom to be neutral the number of protons and electrons have to be the same.
Protons
Explanation: the atomic number is the same as the number of protons
Answer:
116.3 grCO2
Explanation:
1st - we balance the equation so that it finds the same amount of elements of the product side and of the reagent side
C6H6 +15/2 O2⟶ 6CO2 +3 H2O
2nd - we calculate the limiting reagent
39.2gr C6H6*(240grO2/78grC6H6)=120 grO2
we don't have that amount of oxygen so this is the excess reagent and oxygen the limiting reagent
3rd - we use the limiting reagent to calculate the amount of CO2 in grams
105.7grO2*(264grCO2/240grO2)=116.3 grCO2
I think that it is D because the higher the molecular mass, the higher it's boiling point. I hope that helped:) Bye!
