Answer:
The balanced equation is given below:
CH4 + 2O2 → 2H2O + CO2
The coefficient of O2 and CO2 are 2 and 1 respectively.
Explanation:
CH4 + O2 → 2H2O + CO2
The above equation can be balanced as follow:
There are a total of 4 atoms of O on the right side and 2 atoms on the left. It can be balance by putting 2 in front of O2 as shown below:
CH4 + 2O2 → 2H2O + CO2
Now we can see that the equation is balanced.
Therefore, the coefficient of O2 and CO2 are 2 and 1 respectively.
Answer:
the boiling point of HF is higher than H2 and F2
Explanation:
it is because inter molecular give is present in HF because of the Hydrogen bond present. Hydrogen bond is strong and will require much energy to break ,since no hydrogen bond is in the rest H2 and F2 has a low boiling point
mass = Density x Volume
2.00 x 0.160 = 0.32 grams
B. Has natural predators to limit population
