Answer:

H+ and NO3- ions

Explanation:

The Pb²+ ions react with the SO4²‐ ions to form a solid precipitate, i.e. they bond together and undergo a phase change;

On the contrary, the H+ and NO3- ions are aqueous ions before the reaction and the same after the reaction, i.e. they don't change;

Hence, the H+ and NO3- ions are spectator ions

The way to do this type of question is to consider what changes and what doesn't, look at phase changes and oxidation state changes

Answer:

use the equation Q = mc ΔT

Q = heat energy transferred (joules)

m =mass of the liquid being heated (kilograms)

c = specific heat capacity of the liquid (joule per kilogram Celsius), ΔT = change in temperature (Celsius).

The ksp of copper(ii) carbonate, cuco3, is 1.4 × 10-10. calculate the solubility of this compound in g/l.
Mekhanik [1.2K]
To solve for the solubility of this compound:Cu ^ + 2 + CO3 ^ -2 = [x] [x] = x^2 1.4 x 10 ^ -10 = x^2 x = 1.1832 x 10 ^ -5 1.1832 x 10 ^ -5 moles/ L x 123.526 g/mol (molar mass) is equals to 1.5 x 10 ^-3 g/L is the solubility of this compound - CuCO3.
