Question

Given the balanced reaction CH4 + 2O2 -> CO2 + 2H2O2 How many moles of oxygen are needed to completely react with 3.4 moles of CH4? 

CHEMISTRY! sorry i clicked math

Answer 1

6.8 is your answer, 1 mole of CH4 reacts with 2 moles of O2

Answer 2

Answer: 6.8 moles of oxygen are needed to completely react with 3.4 moles of
`CH_4`

Step-by-step explanation:

`CH_4+2O_2\rightarrow CO_2+2H_2O`

According to reaction, 1 mole of
`CH_4` is reacting with 2 moles of
`O_2` then, 3.4 moles of CH_4 will react with :

`=(2)/(1)* 3.4 \text{moles of }O_2` = 6.8 moles of
`O_2`

Hence, 6.8 moles of oxygen are needed to completely react with 3.4 moles of
`CH_4`.
