Answer: C(s) + O2(g) --> CO2(g)12g (C) .... 50.8g (O2)................. initial amounts0g(C) .........18.8g(O2) ................. amounts when reaction completeThat means that C was the limiting reactant, and the amount of CO2 is based on the amount of carbon that burned. Covert 12 grams of carbon to moles. The moles of CO2 will be the same, since they are in a 1:1 mole ratio. Then convert the moles of CO2 to grams.12g C x (1 mol C / 12.0 g C) x (1 mol CO2 / 1 mol C) x (44.0g CO2 / 1 mol CO2) =44 g of CO2
Answer:
15 protons
Explanation:
The atomic number always equals the number of protons inside the nucleus, so if the atomic number is 15, that means 15 protons are present.
Hey there!
D = m / V
0.775 = m / 50.0
m = 0.775 * 50.0
m = 38.75 g
