Answer:

The answer to your question is 7.4 moles of Aluminum

Explanation:

Data

moles of Al = ?

moles of Al₂O₃ = 3.7

Balanced chemical reaction

                4 Al  +  3 O₂  ⇒  2 Al₂O₃

To solve this problem use proportions and cross multiplication. Use the coefficients of the balanced chemical equation.

                4 moles of Aluminum ----------------- 2 moles of Al₂O₃

                 x                                  ----------------- 3.7 moles of Al₂O₃

                            x = (3.7 x 4) / 2

                            x = 14.8 / 2

                            x = 7.4 moles of Aluminum

How much heat is required to heat 9.61g of ethanol (ch3ch2oh) from 24.1 c to 67.3 c?
Rashid [163]
The  heat  required  to heat 9.61g  of ethanol from  24.1 c to 67.3  c  is  calculate as below

Q(heat) = M(mass) xC (specific heat  capacity )  x  delta T (bhange in temperature)

Q=?
M=9.61 g
C= 2.46 j/g/c
deltaT =67.3c - 24.1 = 43.2 c

Q is therefore= 9.61 g  x 2.46 j/g/c x 43.2 c = 1021.27  joules

Why did the French establish settlements along the Great Lakes and the St. Lawrence?
avanturin [10]
I don't think this belongs in the chemistry category. But. The French settled along the st Lawrence because the region had lots of animals that were valued for their fur (e.g. The Beaver) Also they settled there to colonize land and expand their territory.

Is mesosphere is where most of meteoroids begin to burn?
Paha777 [63]

Answer:

The mesosphere is 22 miles (35 kilometers) thick. ... Those meteors are burning up in the mesosphere. The meteors make it through the exosphere and thermosphere without much trouble because those layers don't have much air. But when they hit the mesosphere, there are enough gases to cause friction and create heat.
