Asprin is a compond with the molecular formula, C9H8O4. What is the percent composition?

Chemistry
1 answer:
Arte-miy333 [17]3 years ago
3 0

Answer:

Oxygen       35.6 percent

Carbon        60 percent

Hydrogen    4.4 percent

Explanation:

Molecular mass of aspirin(C_9H_8O_4)=180 gm/mol.

Mass of carbon in 180 gm of aspirine=12\times 9=108\  gm.

Therefore, percentage of carbon in aspirin is =\dfrac{108}{180}\times 100=60\ percent.

Similarly, mass of hydrogen in 8 gm of aspirine=1\times 8=8\ gm.

Hydrogen's percentage in aspirin=\dfrac{8}{180}\times 100=4.4\ percent.

Also, mass of oxygen in aspirin is =16\times 4=64\ gm.

Oxygen's percentage in aspirin=\dfrac{64}{180}\times 100=35.6\ percent.

Hence, this is the required solution.

The list of options to answer this question is:

A.kinectic energy is transformed into thermal energy.

B.electrical energy is transformed into potential energy.

C.potential energy is transformed into kinectic energy.

D.mechanical energy is transformed into chemical energy.

The answer is the option A. A.kinectic energy is transformed into thermal energy.

As you know energy cannot be lost but transformed.

When friction force acts over the tyres it increases the speed of the particles in the tyres which is thermal energy, this thermal energy increase comes from kinetic energy loss.

Choose the correct statement regarding the relative size of atoms:
Sonbull [250]

Answer:

The atoms on left side are larger than the atoms on the right side of the periodic table because those on the right have more proton's.

Explanation:

As we travel along a period in a periodic table then the atomic radii decreases

This is because as we travel along a period we have that the atomic number of the atoms increases which means the the number of proton's increased

But the electron's add to the same outer shell throughout the period , which means the effective nuclear charge increases which pulls the outer electrons toward's the nucleus and the size decreases.

Therefore the atoms on left side are larger than the atoms on the right side of the periodic table because those on the right have more proton's.

  • The difference between single displacement reaction and double displacement reaction are:

Explanation:

in the chemical reaction an atom in a molecule is replaced by another atom forming the end product .this type of chemical reaction involved only two reactants for example zinc + copper sulphate give us copper sulphate + copper.double displacement reaction is the reaction in which two compounds react together to form two other compounds by mutual exchange of other ions is called double displacement reaction.this type of reaction is involved two or more than two reactants.for example AG and O3 + NaCl give us agcl + nano3
