Given the following chemical reaction: 202 ch4 co2 2 h20what mass of ch4 is required to completely react with 100 grams of o2?

Molar mass:

O₂ = 32.0 g /mol             CH₄ = 16.0 g/mol

2 O₂ + CH₄ = CO₂ + 2 H₂O

2 x 32 g O₂ > 16 g CH₄
100 g O₂ > ( mass of CH₄)

mass of CH₄ = 100 x 16 / 2 x 32

mass of CH₄ = 1600 / 64

= 25 g of CH₄

hope this helps!

The closer the atoms are to becoming ionic the more highly dense the negatively charged side gets.
