The type of carbon fixation stores carbon dioxide in acid form is CAM i.e. crassulacean acid metabolism.
What are CAM?CAM stands for crassulacean acid metabolism in this process photosynsthesis is occured at day time but the exchange of gases takes place at night itself only.
In this carbon fixation process, carbon dioxide is stored in the form of organic acid malic acid and losses carbon dioxide at the night time and by doing this it helps in the storage of water.
Hence option (C) is correct.

A sample of iron having a mass of 93.3 g is heated to 65.58 oC and is placed in 75.0 g of water raising the temperature of the water from 16.95 o C to 22.24 o C. Find the specific heat capacity for this iron sample. (Specific Heat of Water (C) = 4.184 J/go C)
Answer:
0.271J/g°C
Explanation:
mass of iron=93.3g
∆°C=65.58
mass of water=75g
C of water=4.184
∆°C=22.4-16.95=5.29°C
mc∆°C of iron = mc∆°C of water
93.3×C×5.29=75×4.184×5.29
C=75×4.185×5.29/93.3×65.58
C=0.271J/g°C
Which of the following helps explain why experiments involving speed and velocity are important? (1 point)
Experiments involving speed and velocity are important because they have not been investigated much and scientists still do not fully understand how speed and velocity are related
Experiments involving speed and velocity are not important because they have already been thoroughly investigated by scientists and there is nothing more to learn.
Repeated experiments with airplanes and how their velocity changes as a result of environmental conditions like wind can help scientists develop a model for flight paths and launch times to
minimize fuel usage
O Repeated experiments that change motivational foods for tortoises on tracks can help scientists determine preferred eating habits
The statement that explain the important of experiment with speed and time is
Repeated experiments with airplanes and how their velocity changes as a result of environmental conditions like wind can help scientists develop a model for flight paths and launch times to minimize fuel usage.
What is an experiment?An experiment is a scientific procedure or technique carried out in a place to discover or test the validity of something.

To what volume should 0.0667 mol of KCl be diluted in order to prepare a 0.250 M solution?
To prepare 0.250 M solution, the 0.0667 mol of KCl should be diluted up to 266.8mL
StoichiometryFrom the question,
We are to determine to what volume the KCl should be diluted, in order to prepare 0.250 M solution
From the formula,
Numer of moles = Concentration × Volume
Then, we can write that
[tex]Volume= \frac{Number\ of\ moles}{Concentration }[/tex]
From the given information,
Number of moles = 0.0667 mole
Concentration = 0.250 M
Then,
[tex]Volume = \frac{0.0667}{0.250}[/tex]
Volume = 0.2668 L
Volume = 266.8 mL
Hence, to prepare 0.250 M solution, the 0.0667 mol of KCl should be diluted up to 266.8mL

Explanation:
The problem with choices A B C D is that the molecular balance numbers are incorrect. E is the only one correctly balanced. For example in A is balanced as
3Mg + 2H2O ===> 3Mg0 + 2H2
The Mg's are correctly balanced.
So are the hydrogens. But take a look at the 0xygens. There are 2 on the left and 3 on the right. The equation is not balanced correctly. B and C have the same problem. One of elements is not balanced correctly.

The enthalpy change of condensation of water is negative and here the entropy change also negative and the process is nonspontaneous.
What is enthalpy change?The enthalpy change of a reaction or a phase change is the change in heat energy absorbed or evolved. The change in enthalpy is dependant on the nature of process as well on temperature of the system.
Condensation of water is the change of its liquid state into solid state. Thus water freezes to form ice. In this process, the system is getting more ordered structure in the solid state and thus, the entropy of the system decreases means the entropy change is negative.
Now, when converting liquid to solid heat is released by the system. Hence, enthalpy change, delta H is negative. A process becomes spontaneous only f its Gibbs energy is negative.
Here we have both negative entropy and enthalpy so make Gibbs energy negative higher temperature is needed.
Condensation of a substances is taking place at very low temperature and thus gibbs energy become positive. Therefore the process is nonspontaneous.
