reeeeeeeeeeeeeeeeeeeeeeee
Explanation:
Answer:
for the cellular respiration the human body needs 1.424 E21 molecules of glucose
Explanation:
mass glucose = 24 g
∴ Mw glucose = 180.156 g/mol
∴ 1 mol ≡ 6.022 E23 molecules
⇒ mol glucose = (24 g)×(mol/180.156 g) = 0.1332 mol glucose
⇒ molecules glucose = (0.1332 mol glucose)×(6.022 E23 molecules/mol)
⇒ molecules glucose = 1.424 E21 molecules
Answer: Positive charge
Explanation:
An atom consists of electron (negatively charged), Proton (Positively charged) and neutron (no charge).
The proton (+) and the neutron (no charge) are in the nucleus of the atom. this makes the resulting charge of the nucleus positive while electron (-) is outside the nucleus.
