igor_vitrenko [27]4 years ago
4 0

Answer:

The answer to your question is: Neutral

Explanation:

A neutral solution is a solution whose pH is 7.

That means that this solution has the same amount of H⁺ and OH⁻.

Examples of neutral solutions:

- distilled water

- sugar solution

- table salt

- cooking oil.

A 20.00 g mixture of magnesium and zinc metal reacting with excess hydrochloric acid produced 1.152 g of hydrogen gas. what is t
mafiozo [28]

percentage of zinc= 5.985/20 X 100= 29.5%

let x represents zinc and y be magnesium so

Zinc(s) + 2HCl(aq) -----> ZnCl2(aq) +  H2(g)

Mg(s) + 2HCl(aq) -----> MgCl2(aq) + H2(g)

1.152 g of hydrogen gas=( x/65.3 + y/24.305) 20

= 3.08 x10^-2 + 0.8295-8.30

=x=5.985

y= 4.015

percentage of zinc= 5.985/20 X 100= 29.5%

The hydrogen gas escapes, so the two products of Zinc Chloride and Magnesium Chloride will then react with Silver Nitrate. Again, I combine both of the reactions

if 315mL of 1.25 M iron(ii) sulfate is added to 405mL of.95 M ammonium phosphate, what is the limiting reactant
vladimir2022 [97]

Answer:

FeSO₄ is the Limiting Reactant

Explanation:

3FeSO₄(aq) + 2(NH₄)₃PO₄ (aq) => 3(NH₄)₃PO₄(aq) + Fe₃(PO₄)(s)

315ml(1.25M)FeSO₄ + 405ml(0.95M)(NH₄)₃PO₄

=> 0.315L(1.25M)FeSO₄       +      0.405ml(0.95M)(NH₄)PO₄

=> 0.394mole FeSO₄           +      0.385mole (NH₄)PO₄

Divide by respective coefficient => the smaller value is the Limiting Reactant.

=> 0.394/3 = 0.131                      => 0.385/2 = 0.193

Smaller value is associated with FeSO₄

∴the limiting reactant is FeSO₄.

Summery:

1. convert reactant quantities to moles

2. divide reactants by respective coefficients of balanced equation

3. note smaller value after dividing by respective coefficient => Limiting Reactant.

The c—c—c bond angle in propane, c3h8, is closest to
Archy [21]
Propane has a molecular formula C3H8.

It is of the form CnH2n+2.
where n = number of C atoms. In present case n = 3.

Each carbon atom in propane is sp3 hydribized. Thus, there are 4 hydrid orbital associated with each carbon atom

The central C atom is sigma bonded to two other carbon atoms and two hydrogen atoms.

Such, sp3 hydridized orbitals are spacial orientated at an  angle of 109^{0}28^{'}, in order to minimize repulsion between the electrons.

Hence, the c—c—c bond angle in propane, c3h8, is closest to 109^{0}28^{'}
