How many grams of Cl2 must react to produce 0.0923 mol of AlCl3? Show work.
alexandr402 [8]

First, let's state the chemical reaction:

2Al+3Cl_2\to2AlCl_3\text{.}

We can find the number of moles of Cl2 required to produce 0.0923 moles of AlCl3, doing a rule of three: 3 moles of Cl2 reacted produces 2 moles of AlCl3:

\begin{gathered} 3molesCl_2\to2molesAlCl_3 \\ \text{?moles Cl}_2\to0.0923\text{ moles }AlCl_3\text{.} \end{gathered}

The calculation would be:

0.0923molesAlCl_3\cdot\frac{3molesCl_2}{2molesAlCl_3}=0.138molesCl_2.

And the final step is to convert this number of moles to grams. Remember that the molar mass can be calculated using the periodic table, so the molar mass of Cl2 is 70.8 g/mol, and the conversion is:

0.138molesCl_2\cdot\frac{70.8gCl_2}{1molCl_2}=9.770gCl_2.

The answer is that we need 9.770 grams of Cl2 to produce 0.0923 moles of AlCl3.

How does the angle at which the sun's rays strike earth affect the number and types of organisms found in different areas of the
zlopas [31]
There's no math to this,
So I don't see why angle is in the question anyways...
The sun provides energy for animals and plants. A cave is a type of ecosystem that almost never sees the sunlight, and a forest is a type of ecosystem that sees the sunlight regularly. The difference between these two is- the caves have animals that have adapted to their environment, I think there's a species called ghost crabs that are blind and are white. This is because sunlight provides the vitamins to pigment skin. I could go on and on

mrs_skeptik [129]

1.the chemical change color from colorless to purple

2. A yellow gas forms

3.a brown solid forms in the bottom of the beaker

4.the temperature of the chemicals rises 15 Celsius

Explanation:

All of the options are proofs that chemical change has occurred.

A chemical change is one with the following properties:

  • A new kind of matter is usually formed as seen by the gas evolution and the formation of the insoluble precipitate i.e brown solid at the bottom of the beaker.
  • They are not easily reversible.
  • Usually accompanied by energy changes as seen in the rise in temperature.
  • Color changes can also infer chemical changes in a reaction.
