Hello my friend! The correct answer to this quastion is "B. carbon + oxygen → carbon dioxide"
Explanation:
Carbon uses oxygen and heat as fuel for the O2 chemical bond breakdown reaction, and the new reaction between carbon and formed oxygen or carbon dioxide.
C + O2 ----> CO2
Answer:
The products will also have one S and four O atoms.
Explanation:
According to Law of Conservation of Matter, " Matter can neither be created nor destroyed, but it can be changed from one form into another".
A nonmetal and a nonmetal will make molecular compounds like H2O and CO2
Answer:
Explanation:
H = 1
C = 12
O = 16
Acetylene, HC≡CH = 2+24 = 26
H2O = 2 + 16 = 18
In XS oxygen, one HC≡CH yields one H2O
26 g HC≡CH ==> 18 g H2O
2000 g HC≡CH ==> 2000*18/26 g H2O = 1384.6154 g H2O
16.94/18=.9411111
sig figs: 0.9411 mole of water
