Answer:

synthesis

Explanation:

  The reaction equation properly written is shown below:

               4Al + 3O₂ → 2Al₂O₃

  A synthesis reaction is a form of combination of atoms. It involves the formation of a single product from two or more reactants.

Decomposition is the formation of two or more products from a single reactant.

Single replacement is a reaction in which one substance is replacing another.

In double displacement, there is an actual exchange of partners to form new compounds.

When a certain powder is mixed into a solution of silver nitrate, a white precipitate forms. When the powder is added to a solut
atroni [7]

Answer:

Ammonium chloride

Explanation:

The powder is:- Ammonium chloride

When mixed with silver nitrate, white prescipitate of silver chloride is formed as:-

NH_4Cl+AgNO_3\rightarrow NH_4NO_3+AgCl

When mixed with sodium hydroxide, ammonia gas is formed which has noxious order.

NH_4Cl +NaOH\rightarrow NH_3 + H_2O + NaCl

Ammonia gas on reaction with nickel (II) hydroxide forms deep blue colored complex as shown below:-

Ni(OH)_2(s) + 6NH_3(aq)\rightarrow [Ni(NH_3)_6]^{2+}(aq) + 2OH^{-}(aq)

A student observes the chemical process described by this equation:
choli [55]

Answer:

Both are equal

Explanation:

Mass of starting material i.e Aluminium is 4.480 * 10^{-23} grams

The weight of oxygen is 2.65 * 10^{-23}

There are 4 atoms of aluminium and 3 atoms of oxygen

Thus, the total mass of starting material is

4 * mass of one atom of aluminium + 6 * mass of one atom of oxygen

4 * 4.480 * 10^{-23} +  6* 2.65 * 10^{-23}

35.1 * 10^{-23} grams

Mass of new substance is also equal to

4 * mass of one atom of aluminium + 6 * mass of one atom of oxygen

4 * 4.480 * 10^{-23} +  6* 2.65 * 10^{-23}

35.1 * 10^{-23} grams
