Answer asap chem! balance the following reaction. choose "blank" if no coefficient is needed. __ alcl3 + __ agno3 →__ agcl + __ al(no3)3

_AlCl₃ + 3AgNO₃  ⇒ 3AgCl + _Al(NO₃)₃

Explanation:

Law of conservation of matter states that matter can neither be created nor destroyed. Hence, during a chemical reaction, the atoms in the reactants must be the same as the atoms in the products and there quantity must also be the same.

In the question, there are three chlorine atoms in reactant but just one chlorine atom in the product side, there is also one nitrogen atom in the reactant side but  three nitrogen atoms in the product side and also there are three oxygen atoms in the reactant and nine oxygen atoms in the product. Hence, the equation is not balanced, the balanced equation is shown below

_AlCl₃ + 3AgNO₃  ⇒ 3AgCl + _Al(NO₃)₃

From the equation above, it can be deduced that the atoms on the reactant side are the same with those on the product side and they both have the same quantity.

3 hours because it is a decent distance.

as given the equation is

2al + 6 hcl > 2 alcl3 + 3 h2(g)

as per equation two moles of aluminum reacts with six moles of hcl to give two moles of alcl3 and three moles of hydrogen gas

given: three moles of al are present and 7 moles of hcl

for three moles of aluminum nine moles of hcl will be required

however as 7 moles of hcl are present so the limiting reagent is hcl

hcl is going to decide the number of moles of product formed

when six moles of hcl are present = 3 moles of h2 are formed

when one mole of hcl is present == 3/6 mole sof h2 will be formed

when 7 moles of hcl are present = 3 x 7/ 6 moles of h2 will be formed = 3.5 moles of h2
