MolarityMolality 1. The number of moles of solute present in per liter of solution.1. The number of moles of solute present in 1kg of solvent. 2. It depends on volume.2. It depends on mass. 3. Volume changes with temperature, hence it is temperature dependent.3. It depends on mass which is independent of temperature. To convert Molality value into Molarity value, we have to use the following formula:- m=1000×(d−M)×Mb1000×M or, M=(m×Mb)+1d where, M: molarity, m: molality, d: density, Mb: Molecular mass.

Inductive effect in simple terms is the result of permanet dipole produced due to polarity of the sigma bond developed due to difference in electronegativity.
This causes a permanent state of bond polarization, where the more electronegative atom has a slight negative charge ({tex}\delta{/tex}-) and the other atom has a slight positive charge ({tex}\delta{/tex}+)

What is dark reaction? in ch photosynthesis in highrr plants.

Posted by Ifra Jehan 3 years, 4 months ago

Entrance Exam > NEET-UG > Biology

1 answers

Yogita Ingle 3 years, 4 months ago

Dark reaction is also called carbon-fixing reaction. It is a light-independent process in which sugar molecules are formed from the carbon dioxide and water molecules.

The dark reaction occurs in the stroma of the chloroplast, where they utilize the products of the light reaction.

Plants capture the carbon dioxide from the atmosphere through stomata and proceed to the Calvin cycle.

In the Calvin cycle, the ATP and NADPH formed during light reaction drives the reaction and convert six molecules of carbon dioxide into one sugar molecule, i.e. glucose.

(K-273)/100=C/100=(F-32)/180 So, (K-273)/100=25/100=(F-32)/180 => K= 298 => F= 77

2Thank You

Gaurav Seth 3 years, 4 months ago

The normal room temperature which would be comfortable for living is around 20 - 25° C.

In chemistry, The upper limit 25°C is taken as Standard room temperature .

We know that,
Temperature on Celsius + 273 = Temperature on Kelvin.

Now,
25°C = 25 + 273 = 298K .

Therefore, The standard room temperature in Kelvin is 298 k
