<u>Answer:</u> The chemical formula is 
<u>Explanation:</u>
Ionization energy is defined as the amount of energy that is required to remove an electron from a chemical species.
The ionization energy equation for the given values follow:



From the values of ionization energy above, it can be seen that the ionization energy increases as every succeeding electron is removed.
Second ionization energy is a little higher than the first one but there is a huge amount of difference between the third and second ionization energy.
This implies that the ion formed during second ionization energy has a stable configuration and it requires a humongous amount of heat to release the third electron.
Hence, the ion formed will be 
Sulfite ion is a polyatomic ion having a chemical formula of 
An ionic compound is formed between the two ions and the chemical compound formed between the two will have a formula of 
Hence, the chemical formula is 
Answer: 234,375 J=234.375 kJ
Explanation:
K= m*V²/2
K=750kg*625m²/s²/2=234375 J
Explanation:
a) 4P + 3O2 --> 2P2O3
b) The chemical reaction above limits the number of molecules of P2O3 produced for every 4 atoms of P.
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.
Answer:
150
Explanation:
- C₄H₂OH + 6O2 → 4CO2 + 5H₂O
We can <u>find the equivalent number of O₂ molecules for 100 molecules of CO₂</u> using a <em>conversion factor containing the stoichiometric coefficients of the balanced reaction</em>, as follows:
- 100 molecules CO₂ *
= 150 molecules O₂
150 molecules of O₂ would produce 100 molecules of CO₂.
