2 × [2] + [3] - [1] ( Using Hess's law)
The enthalpy for given reaction is 232 kilo Joules.
A warm front is also defined as the transition zone where a warmer air mass is replacing a cooler air mass
Dew point: The point at which air saturated with water vapor produces condensation which forms dew.

Plant’s roots can take up water by capillary action.
Answer:
Molecular formula = P₄O₁₀
Explanation:
Given data:
Empirical formula of compound = P₂O₅
Molar mass of compound = 426 g/mol
Molecular formula = ?
Solution:
Molecular formula:
Molecular formula = n (empirical formula)
n = molar mass of compound / empirical formula mass
Empirical formula mass= P₂O₅ = 283.89 g/mol
n = 426 g/mol / 283.89 g/mol
n = 2
Molecular formula = n (empirical formula)
Molecular formula = 2 (P₂O₅ )
Molecular formula = P₄O₁₀
