If the earth is completely an oxidizing atmosphere, materials would ignite spontaneously when they are exposed to air.
<h3>What would happen if the earth is an oxidizing environment?</h3>
Let us recall that oxidation has to do with an increase in oxidation number. If the earth is left as an oxidizing atmosphere without any attenuation, we can not have pure substances.
Secondly, materials would ignite spontaneously when they are exposed to the oxidizing atmosphere of the earth.

The correct answer is Gallium.
The largest temperature range for the liquid state of an element is Gallium
What Is Gallium?
A chemical element called gallium has an atomic mass of 69.72 g.mol^-1. Gallium has an atomic number of 31. In general, gallium is thought to be a soft metal under normal pressure and temperature. Ga stands for gallium.
Properties of Gallium
- A soft metal with an extremely glossy surface is gallium. The color of pure gallium is somewhat silver-blue. Gallium does not exist in its elemental or natural form in the natural world. It must be removed through smelting or some other process. It is incredibly distinct and doesn't resemble metal at all. It is pliable and a knife can be used to cut it.
- It has a relatively low melting point of roughly 29 degrees Celsius. As a result, if your body temperature is higher than 30 degrees Celsius, a portion of it may likely melt in your hands. It is one of the four non-radioactive chemical elements that are liquid at ambient temperature, along with mercury, rubidium, and cesium. Gallium readily adheres to porcelain or glass.

Explanation:
1 mole = 6.02 x 10^23 atoms (Avogadro’s number)
Step 1) Determine how many grams of a substance are in the problem
Step 2) Find the amount of grams in 1 mole of the substance
3) Multiply step one by step two
I think the answer is helium
Answer:
1.5V
Explanation:
We can solve this problem by using the equation of state for an ideal gas, which is:
where
p is the pressure of the gas
V is its volume
n is the number of moles
R is the gas constant
T is the absolute temperature of the gas
In this problem, the pressure and the temperature of the gas are held constant: so we can rewrite the equation as
And so:
Where here we have:
is the initial number of moles
is the final number of moles
is the initial volume of the gas
Solving for V2, we find the new volume:
So, the volume of the gas increases by 1.5 times.
