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.

hey there!

mass = 6.75 g

volume =   9 cm³

therefore:

d = mass / volume

d   = 6.75 / 9

d = 0.7 g/cm³
