Answer:
The breaking of the chemical bonds of a storage molecule transfer energy, no what molecule is stored.
Explanation:
Being successful of plants and animals does not necessary depend on the stored molecule but on the energy being transferred during their breaking.
Answer:
Mg
Explanation:
The element in the third row with two 3s electrons and no 3p electrons is magnesium — Mg.
The interaction between the two atoms of H in H2 with the lower energy corresponds to a covalent bond between hydrogen's.
When the two atoms of H form a bond, they are overlapping the individual orbitals to form a new one. Every hydrogen has 1 electron which sits in a 1s orbital and then form one molecular orbital. The energy of H2 is lower than individual hydrogens because the electrostatic interaction between them.
1 mole ----------- 6.02x10²³ atoms
1.75 moles ------- ?
atoms = 1.75 * 6.02x10²³ / 1
= 1.053x10²⁴ atoms
hope this helps!
