show me the steps for solving this problem how many grams of O2 are required to burn 46.0 grams of C5H12

Answers

Answer 1

Answer: (MM)C5H12=5x12+12x1=72g/mol
(MM)O2=2x16=32g/mol
Acoording to equation:
C5H12 + 8O2 => 5CO2 + 6H2O

The proportion between C5H12 and O2 is 1:8 in mol

So: 72/16=46/x finale x=10,2g of O2

In lemonade, the powder is the solute, and the water is the solvent.

One atom of silicon can properly be combined in a compound witha. three atoms of hydrogen.
b. four atoms of calcium.
c. two atoms of oxygen.
d. one atom of chlorine.

Answers

One atom of silicon is perfectly combined with the $\boxed{{\text{two atoms of oxygen}}}$ and forms silicon dioxide.

Further explanation:

Law of multiple proportions:

This law states that the molecule is a particle that is made up of two or more element. The elements are always combined in a ratio of fixed whole number.

Silicon has electron configuration $\left[{{\text{Ne}}}\right]3{s^2}3{p^2}$ so it can form 4 covalent bonds with other atoms.

One atom of silicon is combined with hydrogen in 1:4 ratio and form ${\text{Si}}{{\text{H}}_4}$ . This compound is known as silane. Thus silicon is not able to combine with three hydrogen atoms.

One atom of silicon is combined with calcium as calcium silicate $\left({{\text{C}}{{\text{a}}_{\text{2}}}{\text{Si}}{{\text{O}}_{\text{4}}}}\right)$ and Calcium silicon $\left({{\text{Ca}}{{\text{H}}_{\text{4}}}{\text{Si}}}\right)$ . Therefore, silicon would not be able to combine with 4 calcium simultaneously.

One atom of silicon is combined with oxygen in 1:2 ratio and form ${\text{Si}}{{\text{O}}_2}$ . This compound is known as silicon dioxide. Thus silicon can combine with two oxygen atoms.

One atom of silicon is combined with chlorine in 1:4 ratio and form ${\text{SiC}}{{\text{l}}_4}$ . This compound is known as silicon tetrachloride. Thus silicon is not able to combine with one chlorine.

A lahar is a type of mudflow that occurs?A. after a volcanic eruption
B. before a hurricane make landfall.
C. after a severe thunderstorm
D. during a tornado

Answers

A lahar is a type of mudflow that occurs after a volcanic eruption. It is a sort of mudflow or trash stream made out of a slurry of pyroclastic material, rough flotsam and jetsam, and water. The material streams down from a fountain of liquid magma, normally along a waterway valley. Lahar is the most deadly by-products of the eruption because of the speed they can travel.

A lahar is a type of mud flow that occurs? The answer is, A. after a volcanic eruption.

Which explains why the lawsmotion are scientific laws?
O A. The theories of motion became laws after there was enough
evidence to prove they were true.
O B. The laws cannot be tested by experiments, but scientists know

What type of intermolecular forces does 2-methylbutane have

Answers

Covalent, as Isopentene (2 methylbutane) is completely non-metallic

Final answer:

2-methylbutane, like similar molecules, exhibits the type of intermolecular force known as London dispersion forces due to its molecular structure of carbon and hydrogen atoms.

Explanation:

The substance 2-methylbutane exhibits the type of intermolecular forces known as London dispersion forces. These forces arise due to temporary shift in electron clouds causing temporary dipoles which induce dipoles in neighboring molecules. This is the simplest type of intermolecular forces and it can occur in all types of molecules, but is the dominant force in nonpolar and symmetrical molecules. Hydrogen bonding or dipole-induced forces do not play a role in this substance as its molecular structure of carbon and hydrogen atoms does not allow for those types of intermolecular interactions.

As the substance 2-methylbutane is a branched variant of butane, it has a slightly different structure, but this does not change the basic type of intermolecular forces present. Other similar molecules like propane and butene also exhibit similar types of intermolecular forces. Remember, intermolecular forces are not intramolecular forces which are much stronger and keep the atoms within a molecule together. Intermolecular forces are what keep molecules attached to each other which greatly effects physical properties of a substance like boiling point.
