A 13.9 - g piece of metal ( specific heat capacity is 0.449 /g^ C)who whose temperature is 54.2 degrees * C was added to a sampl
lubasha [3.4K]

Answer:

26.2g = Mass of water in the calorimeter

Explanation:

The heat absorbed for the water is equal to the heat released for the metal. Based on the equation:

Q = m*C*ΔT

<em>Where Q is heat, m is the mass of the sample, C is specific heat of the material and ΔT is change in temperature</em>

<em />

Replacing we can write:

m_{metal}*C_{metal}*dT_{metal}=m_{water}*C_{water}*dT_{water}

13.9g * 0.449J/g°C * (54.2°C-15.6°C) = m(H₂O) * 4.184J/g°C * (15.6°C-13.4°C)

240.9J = m(H₂O) * 9.2J/g

<h3>26.2g = Mass of water in the calorimeter</h3>

Acid deposition would most likely result in_________
luda_lava [24]

Answer: Acid rain.

Explanation:

According to some experts, acid precipitation can lead to acid rain. Acid rain is a product of chemical reactions caused by the release of compounds such as sulfur dioxide and nitrogen oxides into the air. These substances can form in the atmosphere itself and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.

There are specific theories that nitrogen oxides cause acid rain, in other sulfur oxides, which are produced by the combustion of coal or petroleum products, for example, in thermal power plants, automobile engines, and plants for the production and purification of metals. With water vapor, they produce nitric or sulfuric acid, respectively. This natural disaster is very bad for flora and fauna, it has a particular negative reflection on forests and the aquatic world, especially fish.

During the transamination process, the enzyme transaminases uses ________ as a cofactor.
s344n2d4d5 [400]

During the transamination process, the enzyme transaminases use Pyridoxal pyrophosphate as a cofactor.

All transamination reactions, as well as several amino acid oxylation and deamination processes, involve the coenzyme pyridoxal phosphate. The aminotransferase enzyme's epsilon-amino group of a particular lysine group forms a Schiff-base bond with the aldehyde group of pyridoxal phosphate.

The epsilon-amino group of the lysine residue in the active site is replaced by the alpha-amino group of the amino acid substrate. The ensuing intermediate, a quinoid, undergoes deprotonation to become an aldimine, which is then protonated to become a ketimine by accepting a proton in a different position. Ketamine undergoes hydrolysis, leaving the amino group on the protein complex intact.
