Answer: CF4
Explanation:
Calculate the molar mass of each compound. Divide the molar mass of Carbon by the molar mass of each compound, then multiply the answer by 100 to get the percentage.
CF4= 12+(19X 4)
=12+76= 88 g/mol
%C= 12/88 x 100= 13.64%
CO2= 12+(16 X 2)
12+32= 44 G/MOL
%C= 12/44 x 100= 27.3%
CH4= 12+ (1 X4)
=12+4
=16 G/MOL
%C= 12/16 X 100= 75%
C204
(12X2) + (16X4)
24+64
= 88 g/mol
%C= 24/88 x 100
= 27.3%
Answer:
ion - dipole interactions
Explanation:
Ion - dipole interactions -
It refers to the interaction between the ion and a dipole , ( any species which is capable to get produce slight positive and slight negative charge ) , is known as ion - dipole interactions .
Water is a polar compound , and due to more electronegative oxygen atom , it can have slight negative charge and correspondingly , hydrogen atom can attain slight positive charge , and thereby generates a dipole .
Now , from the question,
The salt when dissolved in water , breaks down to ions , cations and anion , and these ions interacts with the polar water molecules , giving rise to the ion - dipole interactions .
Explanation:
Relation between 
and 
is as follows.
![K_{p} = K_{c} [RT]^{\Delta n}](https://tex.z-dn.net/?f=K_%7Bp%7D%20%3D%20K_%7Bc%7D%20%5BRT%5D%5E%7B%5CDelta%20n%7D)
Given, temperature = 
= (830 + 273) K = 1103 K
R = 8.314 J/mol K
= 1 - 0 = 1
Now, putting the given values into the above formula as follows.
0.5 = 
ICE table for the given reaction will be as follows.
Initial: c - -
Equilibrium: (c - x) x x
= ![[CO_{2}]](https://tex.z-dn.net/?f=%5BCO_%7B2%7D%5D)
= x
Hence, same amount of CaO is produced.
Moles of CaO =
Mass of CaO = 
= 0.310 g
Thus, we can conclude that 0.310 g of CaO produced when equilibrium is established.
Answer:
An atom is a particle of matter that uniquely defines a chemical element . An atom consists of cental nucleus that is usually surrounded by one or more electrons. Each electrons is negatively charged.
