Explain what happens to the light ray when it travels through air and then into water
NemiM [27]

A Change of Course. Light travels faster through air than it does through a denser substance, such as water or glass.

So, when light rays travel through air and meet the surface of the denser substance, they are suddenly slowed down.

When this happens, the light rays bend.

Based on the following reaction, determine how much heat is released if 500. grams of methane is combusted in excess oxygen: CH4
EastWind [94]

Answer:

- 13,150.6kJ

Explanation:

CH4 + 2 O2 ------> CO2 + 2 H2O ΔH= – 890 kJ

The ΔH is enthalpy change of combustion , which is the heat is either absorbed or released by the combustion of one mole of a substance.

ΔH=−890 kJ/mol (released in the combustion of one mole of methane)

using the molar mass  (in grams )of methane to get moles of sample

(237g × 1 mole of CH4)/16.04g=14.776 moles  of CH4

Since 1 mole produces 890 kJ of heat upon combustion, then 14.776 moles will produce

ΔH = 14.776moles of CH4 × 890kJ/1mole of CH4

=13,150.6kJ

Therefore ΔH = - 13,150.6kJ
