Missing question: A possible atomic weight of Q is?
A)12.7.
B)19.0.
C)27.5
D)38.0
E)57.0.
Answer is: possible atomic weight of Q is B) 19.0.
Molecular weight of first molecule is 38.0 g/mol.
Molecular weight of second molecule is 57.0 g/mol.
Molecular weight of third molecule is 76.0 g/mol.
Molecular weight of fourth molecule is 114.0 g/mol.
All four molecular weights can be division only by 19 to get whole number:
Molecule 1 (38 ÷ 19 = 2), molecule 2 (57 ÷ 19 = 3), molecule 3 (76 ÷ 19 = 4) and molecule 4 ( 114 ÷ 19 = 6).
Molecular formulas are than Q₂, Q₃, Q₄ and Q₆.
What is a Lewis acid-base reaction?
In the Lewis theory of acid-base reactions, bases donate pairs of electrons and acids accept pairs of electrons.
A Lewis acid is therefore any substance, such as the H+ ion, that can accept a pair of nonbonding electrons. In other words, a Lewis acid is an electron-pair acceptor.
A Lewis base is any substance, such as the OH- ion, that can donate a pair of nonbonding electrons. A Lewis base is therefore an electron-pair donor.
The Lewis theory suggests that acids react with bases to share a pair of electrons, with no change in the oxidation numbers of any atoms.

Answer:
The ratio is 2:1, that is 2mol C / 1mol O2
Explanation:
First check to see if the equation is balanced. It is so now let's find the ratio.
The ratio is the stoichiomeric coefficient of the element or compound.
Carbon : Oxygen
2C : 1 O2 , so 2:1 ..
Answer:
No
Explanation:
If you heat the air inside a rigid, sealed container, then you are keeping it's mass and volume constant.
Then, Pressure of the container is directly proportional to the temperature.
Gay-Lussac's Law: This law states that the pressure of a given amount of gas when at constant volume is directly proportional to gas's absolute temperature in Kelvin.
So, if Kelvin temperature doubles, the air pressure in the container will also double.
The relationship between Celsius temperature and Kelvin temperature is not linear.
If 
becomes 
, then 
will become 
.
i.e, it is increasing for sure, but doesn't double.
