Answer:
6× 10⁸
Explanation:
We need to find the multiplication of 2 x 10⁴ by 3 x 10⁴.
2 x 10⁴ × 3 x 10⁴
= (3 × 2) x 10⁴ x 10⁴
= 6 x 10⁴ x 10⁴
= 6 × 10⁴⁺⁴
= 6× 10⁸
Hence, the required answer is 6× 10⁸.
(NH₄)₂CO₃ → 2NH₄⁺ + CO₃²⁻

Answer:
Sea breeze moves from the areas of higher pressure on the water in the direction of the areas of lower pressure on land.
Explanation:
Sea breeze moves from the areas of higher pressure on the water in the direction of the areas of lower pressure on land. Whereas, land breeze blows from the areas of higher pressure on land to the areas of lower pressure on water.
