<span>It generally does not mean that there is double the oxygen, but in this case there is double, because the subscript number tells how many atoms of that element are in a particle. In this case, there are two of the oxygen, hence the DI-oxide verbiage, and one of the carbon. When there is only one, it's MONOxide, to indicate only one atom.</span>
Answer:
71,40 C
Explanation: Now let's look at this equation. If you look closely, you can't really get an complete answer, so the answer is this
Hello!
<span>In the celebrated equation e = mc2, the c2 is the </span>proportionality constant of energy and mass.
This famous equation was proposed by Albert Einstein in 1905, and implies that when there is a certain mass, there is a certain amount of Energy associated with it even is the mass is in a steady state. The proportionality constant c² is the speed of light squared.
Have a nice day!
