Answer : The correct answer is C) It bans the exploitation of mineral resources .

Antarctic is south pole of earth , Since it is a polar region so it has extremely cold weather .

Due to colder region , human activity are very less in this area and it will be very rich in mineral resources .

Also due to extreme cold environment no extraction or exploring of mineral can be done in it . Hence we can say option C) It bans the exploitation of mineral resources is correct .

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.

Which fuel is better renewable or non-renewable fuel and give a reason why

Scilla [17]

Answer:renewable

Explanation:Renewables Can Cost Less than Fossil Fuels

These days, the energy produced by renewables is just as affordable as energy produced by fossil fuels, if not cheaper in some cases. Some solar panel projects can even generate power at roughly half the cost of fossil fuels like coal. That's a lot of potential savings.
