If the solution containing the metal complex ion is made acidic, why will the silver chloride precipitate
Ne4ueva [31]

Answer,

For example, silver ion can be precipitated with hydrochloric acid to yield solid silver chloride. Because many cations will not react with hydrochloric acid in this way, this simple reaction can be used to separate ions that form insoluble chlorides from those that do not.

Which incorrect aspect of Rutherford’s model was fixed by Bohr’s model?
dolphi86 [110]

Answer:

Some things that were wrong with Rutherford's model were that the orbiting electrons should give off energy and eventually spiral down into the nucleus, making the atom collapse. Bohr proposed his quantized shell model of the atom to explain how electrons can have stable orbits around the nucleus. To remedy the stability problem, Bohr modified the Rutherford model by requiring that the electrons move in orbits of fixed size and energy.

What is the half-life of sodium-24? EXPLAIN how you determined your answer.
liraira [26]
Half-life is basically how long it takes for a radioactive molecule to get to 1/2 of its original mass.

so if sodium 24 mass was 5g and it's half life was 24years then:

after every 24years 1/2 of 5g would have decayed. so in 48years there will only be 2.5g left.

Consider the reaction when aqueous solutions of chromium(III) chloride and ammonium sulfide are combined. The net ionic equation
Dominik [7]

Answer:

2Cr³⁺(aq) + 3S²⁻(aq) ----> Cr₂S₃(s)

Explanation:

When aqueous solutions of chromium(III) chloride and ammonium sulfide are  mixed together, chromium (III) chloride and ammonium sulfide undergoes a double displacement reaction to produce chromium (iii) sulphide as a precipitate and ammonium chloride which remains in solution.

The general equation of the reaction is given below:

2CrCl₃(aq) + 3(NH₄)₂S(aq) ----> Cr₂S₃(s) + 6NH₄Cl(aq)

The net equation of the reaction is given below:

2Cr³⁺(aq) + 3S²⁻(aq) ----> Cr₂S₃(s)
