Chemistry
1 answer:
lyudmila [28]3 years ago
4 0

Answer:

Fossil fuels are found underneath the Earth's surface at varying depths. These fuels - coal, oil, and natural gas - were formed as a result of the remains of dead plants and organic matter being buried and altered over millions of years.

uranmaximum [27]

Answer: 63.88 atm

Explanation:

To answer this, we use the formula PV = nRT since the asumption is that the gas has an ideal behavior

where number of mole = 2.60 mol, R(gas constant) = 0.08205746 L atm/K mol,

T = 251 ∘C = (251 + 273) K = 524 K, Volume = 1.75 L

Making Pressure the subject of the formula, we have

P = nRT/V = 2.6 * 0.08205746 * 524/2.75 = 63.88 atm

What is the difference between a renewable and nonrenewable resource
ioda

Answer:

Answer in explanation

Explanation:

A renewable source of energy is an energy source that cannot be depleted. It is an energy source with constant abundance and hence it is always in abundance. What we are saying is that they are energy sources that cannot be used up. Although it might sometimes be that it is unavailable at some instances, this does not take away the fact that it is abundant and cannot be depleted, although the strength at different times may vary. Example of renewable energy sources include solar energy, wind energy, hydroelectric power source etc. These sources are never depleted and are in abundance.

Non renewable source of energy are those sources of energy that can be depleted. A good example of this can be seen in fossil fuels. Fossil fuels are usually burned to produce energy. They are used up in the process and it will require an additional amount of fossil fuel to be restocked for the energy to be continually supplied.

Isomers of hydrocarbons have the same _______formula but different ____formula.
Misha Larkins [42]

Answer:

Isomers of hydrocarbons have the <u>molecular</u> formula but <u>structural</u> formula.

Explanation:

Molecules with the same structural formula, but different molecular geometries (spatial arrangement) are called isomers. These differences in the arrangement of the various atoms confer certain differences in chemical properties to the resulting hydrocarbons, even though their chemical composition is the same. There are two types of isomers:

Structural isomers: Here, each atom are connected or bonded in different ways, hence structural isomers may contain different functional groups or pattern of bonding. structural isomers are further divided into: chain, position, and functional group isomers.

Stereoisomers: Here, the connections of the atoms are the same, but the difference is in their orientation in space
