In a redox reaction, one of the reactants must release
Leviafan [203]
Redox reaction is the reduction and oxidation reaction. It is a chemical reaction that involves a transfer of electrons. It can mean loss of oxygen (oxidation) or gain of electrons (reduction). Oxydation is the process of where a sustance loses electrons, gains an oxygen atom/s, loses a hydrogen atom/s.  reduction is the opposite.
In a redox reaction, one of the reactants must release electrons.

Convert 25 gram of carbon dioxide to mold
Rus_ich [418]

The atomic weight of carbon dioxide is about 12.011 + 15.999 + 15.999 = 44.009.

44.009 grams of CO2 = 1 mole of CO2             CO2 = Carbon dioxide

25 ÷ 44.009 ≈ 0.568

About 0.568 moles of CO2

Underneath the ocean floor, methane can exist as a solid known as methane hydrate. Methane hydrate forms when large amounts of m
mezya [45]

Answer:

Methane is present in solid, liquid and gaseous form.

Explanation:

Methane hydrate is present in solid state when the hydrogen-bonded water and methane gas come into contact at high pressures and low temperatures in the deep oceans while on the other hand, methane which is present inside the earth surface in gaseous form due to non-availability of water that can combine with methane. Methane is also found in liquid form when it is cool with high pressure and low temperature.

a compound is found to be 51.38% carbon, 8.64% hydrogen, and 39.97% nitrogen. it has a molecular molar mass of 140,22 g/mol
Vlada [557]

The molecular compound in the given statement is CH₆N₂.

<h3>What defines a molecular compound?</h3>

Chemical compositions of molecules that make up molecular compounds reflect the number of elements that are really bound together within the molecule. Due to the sides and angles of a atoms' links to one another, the complex has a certain structure.

<h3>Briefing:</h3>

Consider 140.22 g/mol of compound

Carbon = 140.22 * 51.38/100

Carbon = 72 gm = 1 mol

Hydrogen = 140.22 * 8.64/100

Hydrogen = 12 gm = 6  mol

Nitrogen  = 140.22 * 39.97/100

Nitrogen  = 56 gm = 2 mol

The molecular compound is CH₆N₂.
