Answer from: allyssaharrisooy50au

aoSrCl2 + a1 Li3PO4 → a2Sr3(PO4)2 + a3 LiCl

The coefficients that will balance the equation above are

ao= 3

a1=2

a2=1

a3=6

explanation

The balanced equation is therefore as below

3SrCl2 +2Li3PO4→ Sr3(Po4)2 + 6 LiCl

3 moles of SrCL2 react with 2 moles of Li3PO4 to form 1 moles of Sr3(PO4)2 + 6 moles of LiCl

The balanced equation obey law of mass conversion of a chemical reaction since the mass of the product is equal to mass of reactant.

for example in reactant side we have 3 Sr which is the same in product side.

Answer from: Quest

answer: - 3.) the oxidation state of nitrogen in no changes from +2 to 0, and the oxidation state of carbon in co changes from +2 to +4 as the reaction proceeds.

solution: - as per the rules, oxidation number of oxygen in its compounds is -2. the sum of oxidation numbers of all the elements of a molecule or compound is zero.

also, the oxidation number in elemental form is zero.

in no, the oxidation number of o is -2 so the oxidation number of n is +2 so that the sum is zero.

similarly, the oxidation number of c in co is +2 and o is -2.

on product side the oxidation number of n is 0 as it is in the elemental form( $n_2$ ) .

oxidation number of c in carbon dioxide is +4 as there are two oxygen in it and we know that each oxygen is -2.

so, oxidation number of n is changing from +2 to 0 and the oxidation number of c is changing from +2 to +4.

since nitrogen is reduced and hence no is acting as an oxidizing agent. carbon is oxidized and so co is acting as a reducing agent.

so, the right choice is number 3.)the oxidation state of nitrogen in no changes from +2 to 0, and the oxidation state of carbon in co changes from +2 to +4 as the reaction proceeds.

Which statements are true concerning mineral formation? check all that apply. the slower the cooling, the larger the crystals. the faster the cooling, the smaller the crystals. crystals formed from magma are smaller than crystals formed from lava. minerals can only form in solutions when the solution is heated deep underground. when a solution cools, elements and compounds leave the solution and crystallize as minerals. minerals formed from hot water solutions can form narrow channels in the surrounding rock.
