A neutron is in the nucleus. The isotope symbol consists of the mass number and atomic number. <span>The mass number is the number of neutrons and protons. </span>
<span>Therefore adding neutrons affects the mass number. This means the symbol is affected.</span>
Answer:
Therefore when 1.26 moles of H₂O is reacted 0.63 mole of O₂ are produced.
Explanation:
The required reaction is
H₂O → O₂+H₂
The reaction is not balance reaction. First we have to balance the reaction.
2H₂O → O₂+2H₂
From the above reaction we conclude that,
2 mole of H₂O produces 1 mole of O₂ and 2 moles of H₂.
∴When 2 mole of H₂O reacts then it produces 1 mole of O₂
1 mole of H₂O reacts then it produces mole of O₂.
1.26 mole of H₂O reacts then it produces mole of O₂.
=0.63 mole
Therefore when 1.26 moles of H₂O is reacted 0.63 mole of O₂ are produced.
We need to know different types of van der Waal's forces.
There are three different van der Waal's forces.
van der Waal's force is driven by induced electrical interactions between two or more atoms or molecules. Though it is very weal in nature, this force is ultimately responsible for liquefaction and solidification of gases.
van der Waal's forces are non-directional. The strength of this force increases as the size of the units linked increases.
There are three types of van der Waal's interactions. They are- (i) Ion-dipole interaction, (ii) dipole-dipole interaction and (iii) hydrogen bond.
Ion dipole interaction is weakest among these three, dipole-dipole interactions are medium and hydrogen bonds are strong interactions.
As mentioned above, phosphoric acid has 3 pKa values, and after 3 ionization it gives 3 types of ions at different pKa values:
H₃PO₄(aq)
+ H₂O(l) ⇌ H₃O⁺(aq) + H₂PO₄⁻ (aq) pKₐ₁
<span>
</span>H₂PO₄⁻(aq) + H₂O(l) ⇌ H₃O⁺(aq) + HPO₄²⁻ (aq) pKₐ₂
HPO₄²⁻(aq) + H₂O(l) ⇌ H₃O⁺(aq) + PO₄³⁻ (aq) pKₐ₃
At the highest pKa value (12.4) of phosphoric acid, the last OH group will lose its hydrogen. On the picture I attached, it is shown required protonated form of phosphoric acid before reaction whose pKa value is 12.4.
C or D! When reduced coenzymes produce in the process of the cycle, are oxidized in the process of oxidative phosphorylation in electron transport chain! I hope this helps :(
