The mass in grams, to five sig figs, of carbon dioxide produced when 22.031 grams of C6H6 is combusted is the same as the mass o
enyata [817]

Answer:

74.566

Explanation:

C6H6 + 02 =6CO2 + 3H2O

2C6H6 + 15O2=12CO2 + 6H2O

mm of C6H6=(12x6)+(6x1)= 72+6 =78gram/mol

mass conc = 2x78=156

mm CO2= 12+(16x2)=

12+32= 44gram/mol

mass conc of CO2 = 12x44

=  528

from The equation

156g of C6H6=528g of CO2

22.031g of C6H6=Xg of CO2

therefore, Xg=

22.031 x 528/ 156

= 74.566g

If two substances combine to form a new substance with different properties, a __________ change has occurred.
Ket [755]

Explanation:

When two substances chemically combine together then it results in the formation of a new compound whose chemical properties are different from the reactant species.

Thus, there will be change in the chemical composition when reactants combine together.

Therefore, we can conclude that if two substances combine to form a new substance with different properties, a chemical change has occurred.

This is the chemical formula for acetone: CH32CO. Calculate the mass percent of carbon in acetone.
olga_2 [115]

Answer:

62.07 %

Explanation:

Chemical Formula =  (CH3)2CO = C3H6O

Mass of C = 12 g/mol

Mass of H = 1 g/mol

Mass of O = 12 g/mol

Mass of  C3H6O = 3(12) + 6(1) + 16 = 58 g/mol

Total mass of C in Acetone = 12 * 3 = 36 g

Mass Percent of C =  Total mass of C / Mass of Acetone   *  100

Mass percent = 36 / 58    *  100

Mass percent = 62.07 %
