And the answer is False,it does not have the same number with particles as the one mole of hydrogen.
Answer:
The dissociation of
is as follows.
![H_{3}PO_{4} \leftrightarrow H^{+}(aq)+H_{2}PO_{4}^{-}](https://tex.z-dn.net/?f=H_%7B3%7DPO_%7B4%7D%20%5Cleftrightarrow%20H%5E%7B%2B%7D%28aq%29%2BH_%7B2%7DPO_%7B4%7D%5E%7B-%7D)
Explanation:
<u>Molecular equation:</u>
In a molecular equation, reactants are present in the molecular form rather than ionic form.
![NaHSO_{3}(aq)+H_{2}O(l)\leftrightarrow H_{2}SO_{3}(aq)+NaOH(aq)](https://tex.z-dn.net/?f=NaHSO_%7B3%7D%28aq%29%2BH_%7B2%7DO%28l%29%5Cleftrightarrow%20H_%7B2%7DSO_%7B3%7D%28aq%29%2BNaOH%28aq%29)
<u>Complete ionic equation:</u>
An ionic equation shows the complete ions in the solution.
![Na^{+}(aq)+OH^{-}(aq)+H_{2}SO_{3}(aq)\rightleftharpoons Na^{+}(aq)+HSO_{3}^{-}(aq)+H_{2}O(l)](https://tex.z-dn.net/?f=Na%5E%7B%2B%7D%28aq%29%2BOH%5E%7B-%7D%28aq%29%2BH_%7B2%7DSO_%7B3%7D%28aq%29%5Crightleftharpoons%20Na%5E%7B%2B%7D%28aq%29%2BHSO_%7B3%7D%5E%7B-%7D%28aq%29%2BH_%7B2%7DO%28l%29)
<u>Net ionic equation:</u>
A reaction shows only those ions are participating in the reaction.
![HSO_{3}^{-}(aq)+OH^{-}(aq)\rightleftharpoons SO_{3}^{2-}(aq)+H_{2}O(l)](https://tex.z-dn.net/?f=HSO_%7B3%7D%5E%7B-%7D%28aq%29%2BOH%5E%7B-%7D%28aq%29%5Crightleftharpoons%20SO_%7B3%7D%5E%7B2-%7D%28aq%29%2BH_%7B2%7DO%28l%29)
The dissociation of
is as follows.
.
The granite loses 1.53 × 10⁸ J of heat.
The formula for the heat (<em>q</em>) transferred is
<em>q = mC</em>Δ<em>T
</em>
I shall assume that the specific heat capacity of granite is 0.790 J·°C⁻¹g⁻¹.
<em>m</em> = 3.580 × 10⁶ g; Δ<em>T</em> = <em>T</em>_f – <em>T</em>_i = -12.9 °C - 41.2 °C = -54.1 °C
∴ <em>q</em> = 3.580 × 10⁶ g × 0.790 J·°C⁻¹g⁻¹ × (-54.1 °C) = -1.53 × 10⁸ J
The granite block loses 1.53 × 10⁸ J.

Answer:</h3>
The equation is balanced since the number of atoms of each element are equal on both side of the equation.
<h3>
Explanation:</h3>
- Balancing chemical equations involves putting coefficient on the reactants and products of a chemical reaction.
- It results to equal number of atoms of each element on either side of the equation.
- A balanced chemical equation obeys the law of conservation of mass such that the mass of reactants is equal to the mass of products.
- The equation; 4AI(s) + 3O₂(g) → 2AI₂O₃(s) is balanced since the number of atoms of each element are equal on both side of the equation.
- That is, 4 aluminium atoms and 6 oxygen atoms on both side of the equation.
