Answer:

1 O₂

Explanation:

In the combustion reaction of hydrogen, oxygen combines with hydrogen to form water as the product of the reaction

Equation of reaction:

2H₂ + O₂ → 2H₂O

From the equation of reaction, it is evident that 2 moles of hydrogen reacts with 1 mole of oxygen to produce 2 moles of water.

Therefore the coefficient of oxygen in the equation is 1.

Comparing the mass of the nucleus with the mass of the protons and the mass of the neutrons refers to what?
DaniilM [7]
E) mass defect 
This is so because the mass defect is the difference between the particles of the nucleous weight and the nucleous itself. According to the equation E=mc^2, the mass defect is related the the binding theory. In order to calculate the mass defect of an atom you need to add up the masses of each proton and each of neutron that are present in the nucleus and then you substract the actual mass of the nucleus from the combined mass.

1. The name of this element is Carbon because there are 6 electrons in the shell.

2. Sorry I didn't learn that. And I don't know.

1. A metal is a solid substance, usually hard. On the other hand, a non-metals is a solid or gaseous material, in which the metallic properties are absent.

2. When a new substance is formed at that time we can understand that chemical reaction has taken place. It can't be reversed.

4. Neutron = no charge

Electron = negative

Proton= positive

5. Nucleus has a positive charge.

6. An atom is bigger. Because electrons are what takes up space in atoms, the result is that the size of the biggest filled orbital determines the size of the atom or ion.
