So you don't jump off a cliff thinking you could fly. Laws and Motion are heavily used in jobs and help us understand more about the mechanics of how earth's gravity operates. Imagine in the future where we could manipulate gravity? That's why we learn and study this so much.
Question
What mass of Al₂O₃ form is produced if 25.00 g of aluminum (al) is reacted completely?, knowing the molar mass of Al₂O₃ is 102 g/mol?
Atomic mass of Al =27 and O = 16
The molar mass of Al₂O₃ = 102.
Mass of aluminium in 102 g of Al₂O₃ = 54 g
54 g Al => 102 g Al₂O₃
25g Al => x g Al₂O₃
x = 25*102/54 = 47.2 g Al₂O₃

Answer:
2,3-dimethylheptane.
CH₃ - CH - CH-CH₂-CH₂-CH₂-CH₂

CH₃ CH₃
Explanation:
Hello there!
In this case, according to the given instructions, it is possible to draw the organic chemical structure by connecting seven carbon atoms along the parent chain with two methyl substituents at the second and third carbon atoms; thus, the resulting structure is:
CH₃ - CH - CH-CH₂-CH₂-CH₂-CH₂
| |
CH₃ CH₃
Furthermore, the name would be 2,3-dimethylheptane according to the IUPAC rules for nomenclature.
Best regards!
Answer:
K=1.93
Explanation:
Given reactions are:
A +2B ⇄ 2C K1=2.79
2C ⇄ D K2=0.186
D⇄ A+ 2B K=?
If we reverse the reaction then the euillibrium constant also become reciprocal of original value:
3rd reaction is a combination of reciprocal of 1st and 2nd reaction
2C⇄A +2B 1/K1;........................1
D ⇄ 2C 1/K2; ..............................2
On adding 1 and 2
D ⇄A +2B 
K=1.93
Answer:
In this process The more dense gases are collected in a gas jar. Carbon dioxide, Nitrogen dioxide are collected by this way. Air is displaced upward thus, this process is known as upward delivery
Hope it helped :)
