The elements are electrically neutral, this is they have the same amount of positive as negative charge.

Electrons and protons have each the same amount of charge but different sign. Eletrons are negative and protons are positive.

Then to be neutral, the number of electrons must be equal to the number of protons. This mean that the element must have 12 electrons.

Answer: 12.

using the same balanced equation, what is the number of moles of carbon dioxide produced from 3.750 moles of propane?
kondor19780726 [428]

Answer:

11.25moles of CO2

Explanation:

First, let us generate a balanced equation for the reaction of propane to produce CO2. This reaction called Combustion. It is a reaction in which propane burns in air (O2) to produce CO2 and H20. The equation is given below:

C3H8 + 5O2 —> 3CO2 + 4H2O

From the equation,

1mole of C3H8 produced 3moles of CO2.

Therefore, 3.750 moles of C3H8 will produce = 3.750 x 3 = 11.25moles of CO2
