Answer:
Combination reaction or synthesis reaction
Explanation:
Given reaction:
CO + H₂O → H₂CO₃
The type of reaction shown above is a combination or synthesis reaction. A combination reaction is one in which a single product is formed from two or more reactants.
In the given reaction carbon monoxide combines with water to produce hydrogen carbonate.
The formation of compounds from the union of their constituent elements falls into this category of reactions.
surrounds the nucleus of an atom in various energy levels called orbitals.
Explanation:
Electrons surrounds the nucleus of an atom in various energy levels called orbitals.
According to the Bohr's model of an atom, the extra nuclear space is made up of electrons in specific spherical orbits called shells or energy levels.
- The region of a maximum probability of where an electron is located is sometimes referred to as an electron cloud or orbital.
- Electrons move round the nucleus in certain permissible orbits.
- An electron in an energy level posses a definite amount of energy associated with it at that level.
- Electrons moves through the energy levels by gaining or losing energy.

Answer:
The answer to your question is 7.64 atm
Explanation:
Data
Volume 1 = V1 = 2.1 l
moles = 4.65
Pressure 1 = P1 = 3.82 atm
Volume 2 = Volume 1/2
Pressure 2 = ?
Process
1.- Calculate the new volume
Volume 2 = 2.10/2
Volume 2 = 1.05 l
2.- Use Boyle's law to find the Pressure
P1V1 = P2V2
-Solve for P2
P2 = P1V1 / V2
-Substitution
P2 = (3.82)(2.1) / 1.05
-Simplification
P2 = 8.022/1.05
-Result
P2 = 7.64 atm
Hi!
The reason for reviewing and replicating work of other scientists is influenced by two factors listed in the answer:
1. An experiment may have had errors that the scientist did not recognize. <u>(unintentional) </u>
2. The results of individual scientists may be influenced by bias. <u>(intentional)</u>
<em>Personal motivations may often influence a scientist to manipulate the results to best suit his/her hypothesis, consequently leading to scientific fraud. </em>
While other options listed are elements of the scientific method, they are not the reasons behind the review and replication of a scientist's work by others.
It’s D. they do have a survival advantage since they are darker.
