Aqueous solutions of silver nitrate (agno3) and iron(iii) chloride (fecl3) are mixed together. which ion combines with the chlor

Anna [14]

The answer is that "Ag+ ion combines with the chloride ion to form a precipitate".

Silver chloride is formed in the form of precipitates, Ag⁺ is a cation and Cl⁻ is an anion so both ions attract each other and combines to form AgCl.

The equation for the ionic reaction that occurs is;

Ag⁺(aq)+Cl⁻(aq)→AgCl(s)

How many grams of oxygen are needed to

Paraphin [41]

Answer:

The value is $M_{o} = 175 g$

Explanation:

Generally the reaction between oxygen and magnesium is

$2Mg_{({s})} + O_2_{(g)} \to 2MgO_{(s)}$

Generally from the law of mass conservation in a chemical reaction we have that

$M_{m} + M_{o} = M_{z}$

Here $M_{m}$ is the mass of magnesium

$M_{o}$ is the mass of oxygen

$M_{z}$ is the mass of magnesium oxide

$425+ M_{o} = 600$

=> $M_{o} = 600 - 425$

=> $M_{o} = 175 g$
