Which of the following formulas has the smallest percent
KiRa [710]

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%

icang [17]

Answer:

Chemical reaction are irreversible. Some of the example of chemical reaction are cooking, rusting, and burning. During a chemical reaction, the composition of substances changes and the particles rearrange to form a new substance. The new substance formed after chemical reaction of substance has different  physical and chemical properties.

When a chemical reaction occur, the atoms or molecules of the substances change its physical and chemical properties such as while cooking of vegetable, the molecules of vegetable undergo changes in their properties and form a new substance which is different from the earlier.
