1. An acetic acid solution that is 60.0% HC2H302 (by mass) contains
d1i1m1o1n [39]

Answer:

A solution of acetic acid that is 60.0% HC₂H₃O₂ (by mass) indicates that it contains 60.0 g of acetic acid and 100.0 g of water.

Explanation:

A percentage is a way of expressing an amount as a fraction of 100. The mass percentage corresponds to physical units of the solutions and they allow to establish more precisely the concentration of the solutions and express them in terms of percentages.

Mass percentage indicates the amount in grams of solute per 100 grams of solution.

So a solution of acetic acid that is 60.0% HC₂H₃O₂ (by mass) indicates that it contains 60.0 g of acetic acid and 100.0 g of water.

2AlCl3 --&gt; 2Al + 3Al2
Eva8 [605]

Answer:

1597,5 gm AlCl3 decomposed

Explanation:

2AlCl3 --> 2Al + 3Al2 If you produce 15 moles of Al, how many grams of AlCl3 decomposed? ​

FIRST, you need to write down the the correct reaction.  Your equation makes no sense

here is the correct question

2AlCl3 --> 2Al + 3Cl2    If you produce 15 moles of Al, how many grams of AlCl3 decomposed?

for every mole of Al produced, we decomposed a mole of ​AlCl3

so we produced 15 moles of Al, so we decomposed 15 moles of AlCl3

15 moles are 15 X 106.5 = 1597,5 gm AlCl3 decomposed

Which type of renewable energy creates electricity by using water currents to spin a turbine?
vovangra [49]

Answer:

Hydropower

Explanation:

I learn whenever Hydro is in a word it means water

Also in the question it is talking about water and wind, solar, nor Biomass has anything to do with water, so you can use the process of elimination and find you will only have Hydropower left.

Hope this helps
