If you had excess chlorine, how many moles of aluminum chloride could be produced from 28.0 g of aluminum?
MaRussiya [10]

Answer:

1.04 moles of AlCl₃

Explanation:

Balanced Equation:  2Al°(s) + 3Cl₂(g) => 2AlCl₃(s)

Approach => convert given data (28 g Al°) to moles. The number of moles  AlCl₃ would equal the number of moles aluminum because coefficients for Aluminum and Aluminum Chloride are equal.

moles Al° = (28g)/(27g/mole ) = 1.04 mole Al°

From balanced equation moles AlCl₃ produced equals moles of Al° produced = 1.04 mole AlCl₃ because coefficients of Al° & AlCl₃.

Answer:

A. Gas atoms subjected to electricity emit bright lines of light

Explanation:

When subjected to electricity, the electrons of a gas atom are <em>excited</em>. From that excited energy level, the electrons eventually go back to their initial state; this <u>transition</u> is done by emitting photons at a specific wavelength (causing an emission of bright lines of light).

Such is the mechanism of gas-discharge lamps tipically found in households.

The formation of condensation on a glass of ice water causes the ice to melt faster than it would otherwise. If 8.00 g of conden
algol13

Explanation:

It is known that heat (Q) required to change the phase of a given sample of mass m will be as follows.

               Q_{f} = mL_{f}    ........ (1)

where,    L_{f} = latent heat of fusion

Similarly,   Q_{v} = mL_{v}[/tex]  ....... (2)

where,     L_{v} = latent heat of vaporization

As it is known that value of latent heat of fusion of water is 334 J/g and latent heat of vaporization of water is 2260 J/g.

Hence, equating both the equations as follows.

          m_{condensation} \times L_{v} = m_{fusion} \times L_{f}

          m_{fusion} = \frac{m_{condensation} \times L_{v}}{L_{f}}      

                         = \frac{8 g \times 2260 J/g}{334 J/g}

                         = 54.13 g

Hence, we can conclude that 54.13 grams of ice will melt.

Answer:

C. 500 cm' of 1.0 mol dmº magnesium sulphate solution.

Explanation:

Let us look at each of the solutions individually;

CaCl2  has three particles

K2SO4 has three particles

MgSO4 has two particles

C2H5OH has only one particle

The number of moles of moles in 250 cm of 2.0 mol dm-3 potassium chloride is 250/1000 * 2 = 0.5 moles having two particles

Also; number of moles in 500 cm' of 1.0 mol dm-3 magnesium sulphate solution= 500/1000 * 1 = 0.5 moles having two particles
