Write a balanced chemical equation depicting the formation of one mole of H2O2(g) from its elements in their standard states.

I am Lyosha [343]

Answer:

$H_2(g)+O_2(g)\rightarrow H_2O_2(g)$

Explanation:

Hello!

In this case, since the formation reaction of a compound is undergone when the pure elements composing it are combined, for gaseous hydrogen peroxide, gaseous diatomic hydrogen and oxygen (standard state) must be combined in order to obtain the gaseous hydrogen peroxide as shown below:

$H_2(g)+O_2(g)\rightarrow H_2O_2(g)$

Whereas it is proved there are two hydrogen and oxygen atoms at each side of the chemical equation and therefore it is balanced.

Best regards!

Answer:

The ability to do work

Explanation:

Energy refers to the ability to carry out work.
It is measured in Joules (J).
Energy may exist in different forms such as potential energy when a body is at rest, kinetic energy when the body is in motion, etc.
Energy can neither be created nor destroyed, however, it can be transformed from one form to another. For example, chemical energy may be transformed into mechanical energy or other forms of energy.

What is the average atomic mass (in amu) of element M?

valkas [14]

An atomic mass unit (symbolized AMU or amu) is defined as precisely 1/12 the mass of an atom of carbon-12. The carbon-12 (C-12) atom has six protons and six neutrons in its nucleus. In imprecise terms, one AMU is the average of the proton rest mass and the neutron rest mass.
