When CH₄ is burnt in excess O₂ following products are formed,

CH₄ + 2 O₂ → CO₂ + 2 H₂O

According to equation 1 mole of CH₄ (16 g) reacts with 2 moles of O₂ to produce 1 mole of CO₂ and 2 moles of H₂O. Hence the products are,

1 mole of CO₂ and 2 moles of H₂O

Converting 1 mole CO₂ to grams;
As,
Mass = Moles × M.mass

Mass = 1 mol × 44 g.mol⁻¹

Mass = 40 g of CO₂

Converting 2 moles of H₂O to grams,

Mass = 2 mol × 18 g.mol⁻¹

Mass = 36 g of H₂O

Total grams of products;

Mass of CO₂ = 44 g
+ Mass of H₂O = 36 g

Total = 80 g of Product

Result:
80 grams of product is formed when 16 grams of CH₄ is burnt in excess of Oxygen.

Answer from: Quest

answer: e. sour taste

explanation: acids are those substances which dissociates in water to give $h^+$ ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

$hcl\rightarrow h^++cl^-$

bases are those substances which dissociates in water to give $oh^-$ ions or accepts $h^+$ ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.

$naoh\rightarrow na^++oh^-$

$nh_3+h^+\rightarrow nh_4^+$
