If you had excess chlorine, how many moles of of aluminum chloride could be produced from 10.0 gg of aluminum? Express your answ

gayaneshka [121]

Answer:

The answer is 0.370moles (3 s.f)

Explanation:

Step 1: write the balanced equation for the reaction

Equation for the reaction:

2Al(s) + 6HCl(g) ---------> 2AlCl3(g) + 3H2(g)

Step 2: Equate the mole of the needed substances

So therefore,

2moles of aluminum will produce 2 moles of aluminum chloride

Note that:

Relative atomic mass of Al = 27 g/mole

And, 27g of Al = 1 mole of Al.

Step 3: Solve for the required number of mole.

2moles of Al = 2moles of AlCl3

Same as

1 mole of Al = 1 mole of AlCl3

27g of Al = 1 mole of AlCl3

10g of Al = (1/27 * 10g) of AlCl3

10g of Al = 0.370moles of AlCl3

The _______ of a wave is a measure of the amount of energy it carries

Bumek [7]

The word that best fits is frequency. The sentence is The frequency of a wave is a measure of the amount of energy it carries. There is a direct relationship between frequency and energy of a wave. The constant of proportionality is h, Planck's constant. So, Energy = h * frequency. So, the answer is frequency.<span> Although you should know that wavelength is related to frequency and so it is also a measure of the amount of energy and it should also be other valid answer.</span>

The diagram below shows three kettles with their powers and the time they take to boil 500cm3 of water. How much energy is trans

Bad White [126]

The energy transferred is given as the product of power and time. The 1.4 kW kettle with boiled water produces 378 kJ of energy.

<h3>What is energy?</h3>

Energy is the quantitative property that determines the work done by the body in the form of heat and light.

The image showing the kettles with time and power is attached below.

Given,

Power of the kettle = 1.4 kW

Time taken = 4.5 minutes

If power = energy ÷ time

Then, energy = power × time

= 1.4 × 0.075

= 0.105 KWh

Therefore, 0.105 kWh or 378KJ is the energy transferred.

AnnyKZ [126]

Answer:

$V=0.048m^3$

Explanation:

Hello,

In this case, since the volume is computed by multiplying the given dimensions as follows:

$V=0.2m*0.4m*0.6m$

The result is shown in cubic meters since each meter is also added:

$V=0.048m^3$

Best regards.

What is the concentration of the hydroxide ion? Given that the concentration of the hydronium ion is 2.3 X 10^-7 M

professor190 [17]

Answer:

4.35 * 10^-8 M

Explanation:

Since the concentration of the hydronium ion= 2.3 X 10^-7 M

And we know that;

[H3O^+] [OH^-] = 1 * 10^-14

[H3O^+] = concentration of the hydronium ion

[OH^-] = concentration of the hydroxide ion

So;

[OH^-] =1 * 10^-14/[ H3O^+]

But [H3O^+] = 2.3 X 10^-7 M

[OH^-] = 1 * 10^-14/2.3 X 10^-7

[OH^-] = 4.35 * 10^-8 M
