WHO CAN HELP ME?!?!?!?!

Chemistry
1 answer:
Lady_Fox [76]3 years ago

Answer:

322.1262g

Explanation:

This question is mole to mole reaction but the answer should be in gram.

4moles of Al gives 2 moles of Al2O3

3.1581 moles of Al gives x moles of Al2O3

Cross multiply

4x= 3.1581×2

4x=6.3162

X=6.3162/4

X=1.57905moles

To convert to gram

Moles ×molar mass

Molar mass of Al2O3 is 204g

Which means 1.57905×204= 322.1262g

A body found with rigor throughout the body
-BARSIC- [3]

Answer:

Can you move a body in rigor mortis?

Rigor mortis -- the lay version of it is stiffening of the joints. It really had nothing to do with the joints. It's the lack of chemical in the body, ATP, which is Adenosine Triphosphate. It goes away and you can now move the extremities easily after rigor mortis is gone away.

A sample of a compound contains 60.0 g C and 5.05 g H. Its molar mass is 78.12 g/mol. What is the compound’s molecular formula?
Inessa [10]

A sample of a compound contains 60.0 g C and 5.05 g H.

divide by molar mass of C(12) and H(1) to get molar ratio

C: 60/12=5 and H: 5/1=5

so C:H=5:5=1:1

total molar mass=78

divide by 1C+1H to find the formula: 78/(12+1)=78/13=6

compound is C6H6
