Given the balanced equation representing a reaction occurring at 101.3 kilopascals and 298 k. 2h2(g) + o2(g) → 2h2o(l) + energy

what is the net amount of energy released when one mole of h2o(l) is produced?

I believe the answer will be 285.8 kJ
The reaction above is for two moles of water; therefore we divide the amount of energy by half. 
The enthalpy of formation of a substance is the energy absorbed or released when one mole of a substance is formed from its constituents elements. For example the enthalpy of formation of water is 285.8 kJ/mol

Igoryamba

Answer: Polythene

Polythene is a synthetic polymer classified as plastics.

Explanation:

Polythene is formed artificially from several repeating units of ethene molecules (monomers) in a reaction known as polymerization.

The polyethene can be represented as [CH2-CH2]n, where n is thousands to ten thousands unit of ethene.

It is used to make

- plastic bags,

- cable insulators

- plastic crates etc

Thus, polythene is a synthetic polymer of ethene, and classified as plastics.

Brainllest! Why are they called hot air balloons and not cold air balloons? Be sure to use the terms density, volume, and mass i
Feliz [49]
Hot air balloons have hot air inside them, which is less dense as the air around it. Thus it rises. A cold air balloon would sink because the air would be more dense than the air around it. Also, the balloon’s volume would vary in size depending on the weight of the balloon.

In a furnace zinc is a gas but lead is a liquid. <br><br> Suggest why?
Tems11 [23]

I believe it is because, Lead has a higher boiling point than zinc. by the time Lead melts and becomes a liquid, the temperature is way higher than the boiling point of Zinc therefore, Zinc becomes a gas.
