Answer: 207.217 amu
Work:
203.973 amu *(0.014) = 2.855 amu
205.974 amu *(0.241) = 49.639 amu
206.976 amu *(0.221) = 45.741 amu
207.977 amu *(0.524) = 108.979 amu
2.855 + 49.639 + 45.741 + 108.979 = <em><u>207.217amu</u></em>
Explanation:
Answer:
CH4 + 2O2 -> CO2 + 2H2O
Explanation:
This reaction involves the combustion of methane (CH4)
General form of balancing reactions involving combustion of hydrocarbons is
CxHy + [x+(y/4)]O2 -> xCO2 + (y/2)H2O
x= the number of carbon atoms in the compound = 1
y= the number of hydrogen atoms in the compound = 4
CH4 + [(1+(4/4)]O2 -> CO2 + (4/2)H20
CH4 + (1+1)O2 -> CO2 + 2H2O
CH4 + 2O2 -> CO2 + 2H2O
You're correct, (D) Br is the least reactive non-metal out of this list.
