Answer:
B.Four hydrogen nuclei combine into one helium nucleus.
Explanation:
Mass energy which is stored in a matter itself can be very powerful. A small amount of mass can result in a very large amount of energy as the speed of light is very large.
If we consider the two elements hydrogen and helium, a hydrogen nucleus is made of one proton and a helium nucleus is made of two protons and two neutrons.
The mass of hydrogen is 1.6726 x 10–27 kg, and the mass of helium is 6.6465 x 10–27 kg.
Four hydrogen nuclei combine into one helium nucleus would lead to decrease of total mass, and thus a release of energy such that the number of particles involved remains same.
There are two carbon atoms in every ethanol molecule, so there would be 60 carbons all together.
I hope this helped you!
Answer:
Some worms are nocturnal and some a diurnal
Explanation:
Variation is difference between cells, individual organisms, or groups of organisms of any species caused either by genetic differences (genotypic variation) or by the effect of environmental factors on the expression of the genetic potentials (phenotypic variation).
NOTE:these are of the same species.
To convert milliliters to liters, you should divide the milliliters by 1000. When we do that here, we will see that there are 0.0456 liters in 45.6 milliliters.
Answer The ethanol is stabilized by strong intermolecular forces between the molecules.wer:
Explanation:
During the phase change represented by the heat of fusion the temperature does not change. The molecules in the liquid state has a higher degree of freedom but are stabilized by the strong hydrogen bonding requiring a larger into of energy to separate the molecules than the heat of fusion.
