Ag+ and Pb+2 are two cations that are suggested as producing insoluble halide salts when studying salts containing the halide anions, cl- and br-. First, the charge's number is provided.
Neutral binary salts, also referred to as halide salts, are mixtures of metals and non-metals. The non-metal behaves in a reduced oxidation state at all times. They are the outcome of mixing a hydroxide and hydracid. halide salts of haloids are produced by the reaction of a hydroxide and a hydracid.
Ions are cations with positive charges. They emerge when the electrons of an elemental metal are lost. However, they don't lose any protons; they only lose one or more electrons. To denote a cation, the charge is superscripted following the element name or chemical formula.

Answer:
a. overuse of resources is the correct answer.
Explanation:
Renewable resources are available and they are abundant but overuse of these renewable resources will have a negative effect on the surroundings and humans.
Overuse of renewable resources will leads to the depletion of these renewable sources in the future and will also make the ecosystem unbalance.
Renewable resources are solar energy, geothermal energy, biomass energy, wind energy, hydro energy.
Thus renewable resources are threatened due to overuse and it must be carefully used.
Answer:
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to calculate the concentration of the solution obtained, by knowing 20 mL of water are the same to 20 g and therefore the mass of the solution is 40g+20g=60g.
Next, we apply the following equation to obtain the required concentration:
