HELP! URGENTLY NEEDED! The coefficient/s will balance the chemical equation CH4 +O2 » CO2 + H2O is

a
1, 2, 1, 2
b
2, 1, 1, 2
c
2, 2, 1, 1
d
1, 1, 1, 2

The coefficients : a. 1,2,1,2

Given

Reaction(unbalanced)

CH4 +O2 » CO2 + H2O

Required

The blanced equation

Solution

Give a coefficient

CH4 +aO2 » bCO2 + cH2O

Make an equation

C, left=1, right=b⇒b=1

H, left=4, right = 2c⇒2c=4⇒c=2

O, left=2a, right=2b+c⇒2a=2b+c⇒2a=2.1+2⇒a=2

The equation becomes :

CH4 +2O2 » CO2 + 2H2O

the leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.

it's filtration, but this is an assumption so my apologies if i got this
