science of love
,EXPLANATION:
The initial happy feelings of being in love is stimulated by 3 chemicals in the brain: noradrenaline that stimulates adrenaline production causing that racing heart and sweaty palms; dopamine, the feel-good chemical; and phenylethylamine that is released when we're near our crush, giving us butterflies in our tummies.

Explanation:
The glycosidic bond forms between the carbon atom on the glucose molecule and the nitrogen atom present on the nitrogenous base. A diagram has been attached to show this particular bond. There is also a phosphate molecule bonded on the sugar molecule at the other end.
So this isn’t a question ?
Answer:
1 mol of K
Explanation:
The reaction is: 2K + Cl₂ → 2KCl
2 moles of potassium react with 1 mol of chlorine to make the salt, potassium chloride
If you see the stoichiometry from reactants, 2 moles of K need 1 mol of Cl₂ to react, so 1 mol of Cl₂ needs 2 moles of K, to react too.
We can make a rule of three, to reach the answer:
1 mol of Cl₂ needs 2 moles of K to react
Then, 0.5 moles of Cl₂ must react with (0.5 . 2) / 1 = 1 mol of K
