The limiting reactant is chlorine (Cl2).

<u>Explanation</u>:

Limiting reactant is the amount of product formed which gets limited by the reagent without continuing it.

2 Al + 3 Cl2 ==> 2 AlCl3 represents the balanced equation.

Number of moles Al present = 34 g Al x 1 mole Al / 26.98 g

= 1.260 g moles of Al

Number of moles Cl2 present = 39 g Cl2 x 1 mole Cl2 / 35.45 g

= 1.10 g moles of Cl2

Dividing each reactant by it's coefficient in the balanced equation obtains:

1.260 moles Al / 2 = 0.63 g moles of Al

1.11 moles Cl2 / 3 = 0.36 g moles of Cl2

The reactant which produces a lesser amount of product is called as limiting reactant.

Here the Limiting reactant is Cl2.

Which substance is an example of a nonpolar compound?(1 point)

Tatiana [17]

The answer is B - vegetable oil.

Explanation:

The properties of liquids depend on the attractions the molecules of the liquid have for each other and for other substances.

Liquids can dissolve certain other liquids, depending on the attractions between the molecules of both liquids.

Polar liquids, like water, dissolve other liquids which are polar or somewhat polar.

Polar liquids, like water, do not dissolve non-polar liquids like oil.

The skeletal structure in line-angle (line-bond) mode of 2,3,3,5-tetramethylhexane is shown. Identify the number of hydrogen ato

Kruka [31]

Answer:

There are 22 hydrogen in 2,3,3,5-tetramethylhexane (C10H22)

From the left to the right of the skeletal structure:

1st Main Carbon = 3 hydrogen

2nd Main Carbon = 1 hydrogen

1st Branch Carbon = 3 hydrogen

3rd Main Carbon = 2 hydrogen

2nd Branch Carbon = 3 hydrogen

3rd Branch Carbon = 3 hydrogen

4th Main Carbon = 0 hydrogen

4th Branch Carbon = 3 hydrogen

5th Main Carbon = 1 hydrogen

6th Main Carbon = 3 hydrogen

Total = 22 hydrogen

Explanation:

This is the skeletal formula for 2,3,3,5-tetramethylhexane - the 2D chemical structure. It is an organic compound. The carbon atoms in the structure are known as the carbon backbone. The hydrogen atoms are linked to the carbon backbone. This provides each carbon atom with four bonds.

Why does neon have a smaller atomic radius than lithium?

ladessa [460]

Neon has a smaller atomic radius do it having less of an electron shield. Also the more protons an element has the tighter it is held together making it smaller.

Consider the insoluble compound cobalt(II) hydroxide , Co(OH)2 . The cobalt(II) ion also forms a complex with ammonia . Write a

Nuetrik [128]

Answer:

4.56×10^-10

Explanation:

Co(OH)2(s)<------->Co^2+(aq) + 2OH^-(aq)

Co^2+(aq) + 6NH3(aq) ---------->[Co(NH3)6]^2+(aq)

Overall equation:

Co(OH)2(s)+ 6NH3(aq) ---------->[Co(NH3)6]^2+(aq) + 2OH^-(aq)

The increased solubility of the cobalt salt in the presence of ammonia is as a result of the formation of the hexammine cobalt II complex shown above.

Knet= Ksp×Kf

Ksp of Co(OH)2= 5.92 × 10^-15.

Kf= 7.7 x 10^4

Knet= 5.92 × 10^-15 × 7.7 x 10^4

Knet= 4.56×10^-10

Note Knet is the equilibrium constant of the overall reaction.
