Identify The Combustion Reaction

Answers

Answer 1

Answer:

C₄H₁₂ + 7O₂ --> 4CO₂ + 6H₂O

Explanation:

Organic molecules react with O2 to create water and CO2 in combustion processes. C4H12 is an organic molecule that combines with O2 to create water and CO2 as shown in the reactions.

As a result, this is the sole reaction that obeys the general combustion equation.

What is the "modern" definition of atomic theory?

Answers

the atomic theory states that all matter is composed of atoms.
Atoms themselves are composed of protons, neutrons, and electrons. Each element has its own atomic number, which is equal to the number of protons in its nucleus.

Answer:  The modern atomic theory states that atoms of one element are the same, while atoms of different elements are different. Each element has its own characteristic atomic number. Atoms of the same element can have different numbers of neutrons, however.

The radioactive decay of Uranium-238 releases alphas particles and results in a mass change of 0.135 g. Determine the amount of energy released by this reaction

a) 1.22 x 10^13J

b) 1.22 x 10^16J

c) 4.05 x 10^4J

d) 4.05 x 10^7J

Answers

This question involves the concept of binding energy.

The amount of energy released by this reaction is "a) 1.22 x 10¹³ m/s".

What amount of energy is released?

The amount of energy that is released during the radioactive decay of any element is known as binding energy. This can be given by using the following formula:

[tex]E=\Delta mc^2[/tex]

where,

E = energy released = ?Δm = mass change = 0.135 g = 1.35 x 10⁻⁴ kgc = speed of light = 3 x 10⁸ m/s

Therefore,

E = (1.35 x 10⁻⁴ kg)(3 x 10⁸ m/s)²

E = 1.22 x 10¹³ m/s

Scientists hypothesize that Earth's first oceans were made of fresh water. How did oceans obtain fresh water?
*
1 point
Water vapor in the early atmosphere cooled and fell to Earth as rain.
Frozen comets that fell to Earth melted as they traveled through the atmosphere.
As soon as icecaps formed, they melted because Earth was still very hot.
Early terrestrial organisms exhaled water vapor, which condensed to form fresh water.

Answers

The earth's first oceans would have obtained freshwater as a result of the condensation of water vapor in the atmosphere back then.

How were oceans formed?

The freshwater of oceans was hypothesized to have been formed by the condensation of water vapor present in the early atmosphere of the earth.

The water vapor was thought to have emanated from volcanic activities. The condensation was in the form of rain and the resulting puddles merged together to form the oceans.

Functional groups are the specific groups that provide characteristic properties. The compounds are butanoic acid and methyl propanoate.

What are functional groups?

Functional groups are the active side atoms and molecules that confer the physical and chemical properties of the compound. In the first compound, the functional group is the carboxylic acid (COOH) and four carbon atoms hence, the compound is butanoic acid.

In the second compound, the functional group is an ester (RCOOR) and contains a methyl group and other three carbon atoms making the compound, methyl propanoate.

Which part of the cell was most directly responsible for the shrunken appearance of the cell?

Answers

If a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink.

What is osmosis ?

Osmosis is the net movement of water across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration.

This may sound odd at first, since we usually talk about the diffusion of solutes that are dissolved in water, not about the movement of water itself.

If a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink.

In an isotonic environment, there is no net water movement, so there is no change in the size of the cell.

When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell.

Therefore If a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink.
