What is the equivalent of 0 Kelvin on the Celsius scale?
Answers
0 = C +273
-273 = C
some people use 273 or 273.15 just depends on the teacher.
Final answer:
0 Kelvin, also known as absolute zero, is equivalent to -273.15 degrees on the Celsius scale. Both scales are linearly related with the Kelvin scale starting at the lowest possible theoretical temperature.
Explanation:
The equivalent of 0 Kelvin on the Celsius scale is -273.15 °C. The Kelvin scale is an absolute temperature scale used commonly in science. This scale is based on absolute zero, which is theoretically the lowest possible temperature and is assigned the value of 0 Kelvin. This is the point at which there is no molecular motion and, therefore, no thermal energy. The Kelvin and Celsius scales are linearly related; one-degree change in temperature is the same on both scales. On the Celsius scale, which is defined with the freezing point of water at 0 degrees and the boiling point at 100 degrees, absolute zero or 0 Kelvin falls at -273.15 degrees Celsius.

Since the number of moles of acid will not change, we can use this formula:
M1 V1 = M2 V2
Where M is the concentration of the acid in the solution
V1 = 10 mL
and
V2 = Vwater + 10
If we add an additional 5 mL of acid, the new concentration of the acid will be:
M = (M1 (5mL) + M2 (Vwater + 10mL)) / (5mL + Vwater + 10mL)
The concentration of acid in the new solution will increase.

The thrust is not the type of plate boundary.
The outer surface of the earth has been said to be composed of tectonic plates. The tectonic plates give rise to the shape of the zigzag puzzle. The puzzled plate boundaries are present in varying forms based on their shape.
The plate boundaries can be convergent. In this type of boundary, the earth's crust has been coming towards each other. They have been found between the Indian Plate and the Eurasian Plate.
The divergent plate boundary arises in the form of the earth crust moving away from each other. This will give rise to the mountain ranges.
The transform type of plate boundary has been formed when the tectonic plates slide over each other. This type of boundary has resulted in the San Andreas Fault.
The thrust is not the type of plate boundary.

Answer : The temperature will be, 392.462 K
Explanation :
According to the Arrhenius equation,
or,
where,

= rate constant at
=
= activation energy for the reaction = 66.41 kJ/mole = 66410 J/mole
R = gas constant = 8.314 J/mole.K
= initial temperature = 293 K
= final temperature = ?
Now put all the given values in this formula, we get:
Therefore, the temperature will be, 392.462 K

The statement which is correct is the one stating that the pOH of solution is 12.0.
What is pOH?
pOH is defined as the measure of determining the alkalinity or basicity of the solution.It is also used for the determination of the concentration of the hydroxyl ions which are present in the solution.
Mathematically, it can be defined as the negative logarithm of the hydroxyl ion concentration present in a solution,that is,
pOH= -log(OH)
It can be used for the purpose of an indicator for determining the alkalinity of the substance where the pH values lies above 7.It also finds application in determining the electrical conductivity as well.It is related to the pH by the equation,
pH+pOH=14
For determining the amount of corrosion ,pOH can be used as an indicator for an electrolyte's conductivity.Hence, it can be concluded that higher the pOH ,higher the alkalinity and higher is the amount of corrosion.
