The products obtained from the dissociation of HNO₃ in water are hydronium ion, H₃O⁺ and nitrate ion, NO₃¯
An acid is a substance which when dissolved in water produces hydronium ion, H₃O⁺ as the only positive ion.
Strong acid ionize completely in water while weak acid only ionize to a certain degree (i.e partially) in water
Trioxonitrate (v) acid, HNO₃ is a strong acid and will ionize complete in water to form hydronium ion, H₃O⁺ and nitrate ion, NO₃¯ as illustrated below:
HNO₃ + H₂O —> H₃O⁺ + NO₃¯
Thus, the products for the dissociation equation are: hydronium ion, H₃O⁺ and nitrate ion, NO₃¯

Answer:
1x10^-3M
Explanation:
Data obtained from the question include:
pH = 3
[H3O+] =?
The concentration of the hydronium ion [H3O+] can be obtained by using the formula pH = - Log [H3O+] as illustrated below:
pH = - Log [H3O+]
3 = - Log [H3O+]
Divide through by - 1
- 3 = Log [H3O+]
Take the anti-log of - 3
[H3O+] = 1x10^-3M
Therefore, the concentration of the hydronium ion [H3O+] is 1x10^-3M
The answer is burning wood with campfire if im wrong correct me but im pretty sure ti is
Answer:
Explanation:
To know the temperature at which KCl dissolves in water we need to refer to the general solubility curves.
In the case of , of it will dissolve in of water at a minimum temperature of .
So, the the minimum temperature needed to dissolve 35 grams of KCl in 100 grams of water is .
Answer: 0.52849 j /g °C
Explanation:
Given the following :
Mass of metal = 36g
Δ Temperature of metal = (28.4 - 99)°C = - 70.6°C
Mass of water = 70g
Δ in temperature of water = (28.4 - 24.0) = 4.4°C
Heat lost by metal = (heat gained by water + heat gained by calorimeter)
Quantity of heat(q) = mcΔT
Where; m = mass of object ; c = specific heat capacity of object
Heat lost by metal:
- (36 × c × - 70.6) = 2541.6c - - - - (1)
Heta gained by water and calorimeter :
(70 × 4.184 × 4.4) + (12.4 × 4.4) = 1288.672 + 54.56 = 1343.232 - - - - (2)
Equating (1) and (2)
2541.6c = 1343.232
c = 1343.232 / 2541.6
c = 0.52849 j /g °C
