Answer:
Phosphate possess ATP molecule which provides energy to the DNA or RNA molecule for the movement of the nucleus
Explanation:
Along with the Nucleic acids , bases , phosphate molecules bonds with the 4 oxygen atoms in the structure . it has real importance in the DNA structure for providing the energy of ATP to the molecule
First, we calculate the number of moles of each reactant using the formula:
Moles = mass / molecular weight
CaO:
Moles = 7.15/56 = 0.128
Water:
Moles = 152/18 = 8.44
The reaction equation shows that the reactants must be present in an equal number of moles, so CaO will be the limiting reactant and 0.128 mole of calcium hydroxide will form.
The energy released is given by:
Heat of reaction * number of moles
= -64.8 * 0.128
= -8.29 kJ
8.29 kJ of energy will be released
Answer:
two electrons are lost by magnesium to form magnesium ion (Mn+2) and gained by two oxygen atoms (O-)
Fusion and fission are both nuclear reactions that produce energy, but fusion is two nucleus joining (think about fuse or fusing), while fission is a nucleus splitting (think about fissure)
so the correct answer is <span>C. Fission is the splitting of a nucleus</span>
