A 54.0 g sample of solid water at its normal melting point is subjected to the addition of heat until all of the sample has boiled into a gas at its normal boiling point temperature and pressure. How many kilojoules of heat were added to this sample?

For water;

Part 1:

How many kJ of heat are necessary to melt the solid H2O?

Part 2:

How many kJ of heat are necessary to warm the liquid H2O from 0.00 oC to 100.0 oC?

Part 3:

How many kJ of heat are necessary to boil the H2O, once at the boiling point?

Part 4:

What is the total amount of heat energy, in kJ, needed to heat a 54.0 gram sample of H2O(s) from 0.0 oC until it has completely boiled?

Calculate Δ𝐻, Δ𝑆, Δ𝑆𝑠𝑢𝑟, 𝑎𝑛𝑑 Δ𝑆𝑢𝑛𝑖𝑣 when 4.31 moles of H2O(g) condenses at 58 oC at 1.0 atm until it is a liquid. Assume that all heat capacities and enthalpy changes are constant. And given 𝐶𝑝,𝑙 = 75.3 𝐽 𝐾 𝑚𝑜𝑙 ,𝐶𝑝,𝑔 = 35.9 𝐽 𝐾 𝑚𝑜𝑙 ,𝑇𝑣𝑎𝑝 = 100 𝐶, Δ𝑣𝑎𝑝𝐻 40.7 𝑘𝐽 𝑚𝑜𝑙

How does the Calvin cycle rely on the light-dependent reactions?​

Light independent reactions of the Calvin cycle generally occur only in the light. While not detecting light directly, how do the regulators of the Calvin cycle respond to the presence or absence of light? What is actually being detected

In your own words type the questions of the following. Check the picture for the questions.

A DNA molecule that was 6000 bases long was cut with a restricted enzyme. The restricted enzyme cut the DNA at three sites: 
- Immediately after the bass at position number 600
-  immediately after the bass at position number 3200 
-  immediately after the bass apposition number 5100 
After the DNA molecule was cut, the resulting fragments were separated by gel electrophoresis and then blotted onto a membrane. A labeled probe with the sequence GGACCCT was then added to the membrane. 
The probe will bind to the fragment that has : 
a) 600 bases 
b) 1900 bases
c) 2600 bases
d) 5100 bases
