Voltage<span> is </span>electric potential energy<span> per unit charge, measured in joules per coulomb ( = volts). It is often referred to as "electric potential", which then must be distinguished from </span>electric potential energy<span> by noting that the "potential" is a "per-unit-charge" quantity.

RADIATION. Radio waves, microwaves, IR, light, UV, x-rays, GAMMA waves etc are ALL Electromagnetic radiation. The difference between ALL the above is the frequency, I.E. The number of waves per second. The higher the frequency the more energy.
Answer:
its molecular formula must be C10H16O with 2 rings.
Explanation:
the number of rings of the camphor has to be calculated, we have M + = 152.12 in the mass spectrum and it has three double bonds and one ring. The base beak has great abundance.
Since camphor is a single ketone, and M+/MC = 12 ~~ 8, its molecular formula must be C10H16O, accordingly, the number of rings = (10 * 2-16)/2 = 2.
Answer:
The chemical equation can be written as:
2Mg+O
2
→2MgO
48 g of Mg reacts with 32 g of O
2
.
Thus, 4.8 g of Mg reacts with 3.2 g of O
2
.
Now, 32 g of O
2
forms = 80 g of MgO.
3.2 g of O
2
produces =
32
80
×3.2 = 8 g of MgO.
