How many kilojoules are given off when 17.8 mol of CH4(g) react? CH4(g) + 2O2(g) → CO2(g) + 2H2O(ℓ) ΔH = −890.1 kJ

b. atoms in metallic solids are not arranged in a regular pattern

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but
