<u>Answer:</u>
The Calvin cycle converts ATP and NADPH to "convert CO2 to sugar".
<u>Explanation:</u>
When carbon dioxide reaches inside the leaf through pores called stomata in plants and spreads to the chloroplast stroma, it act as the location of Calvin cycle reactions where sugar is naturally produced.The light-independent processes are also called such reactions as they are not primarily guided by light.
The Calvin cycle processes can be separated into three main channels: carbon fixation, reduction, and starting molecule's regeneration as explained below:
- <u>Carbon Fixation:</u> Six-carbon compound are generated in this step that bifurcate into two molecules (three-carbon compound) 3-phosphoglyceric acid (3-PGA), catalyzed by the enzyme rubisco or RuBP carboxylase/oxygenase.
- <u>Reduction: </u> In this phase of the cycle 3-PGA molecules are converted into glyceraldehyde-3-phosphate (G3P) i.e three-carbon sugar by using ATP and NADPH.
- <u>Regeneration:</u> Many G3P molecules are used to generate glucose, while others have to be recycled to recreate the acceptor RuBP.
Answer:
The calculated concentration of HCl will be less than actual.
Explanation:
Suppose during titration, the <em>HCl</em> was taken in burette and the <em>NaOH</em> in the volumetric flask.
Now we will use equivalence formula for the calculation of concentration of HCl.
Where L.H.S is for hydrochloric acid and R.H.S is for sodium hydroxide. The terms N and V represent normality and volume respectively.
If we calculate for
We see that if the volume of the HCl is greater then the concentration of the HCl will be reduced.
Answer:
ΔH = -55.73 kJ/mol
Explanation:
Since the density of water is 1 g/ml and the problem wants us to use this value to find the mass of NaOH and HNO3 we arrange the original equation of
Since no heat was lost or gained
qrxn+qsoln=0. ----> qrxn=-qsoln.
qsol = mc*()
The mass of the solution is the mass of NaOh and HNO3. 100+100= 200.
You plug in the remaining numbers using 4.18 as the heat capacity and 2 as the change in temperature:
qsol=200*(4.18)*(2)= 1672 J
qrxn= -1672 J
Now ΔH = qrxn over the amount in moles or grams. This problem asks for NaOH in moles. To calculate this we use the concentration formula
M= . -----> n=V*M.
Note that you must convert 100 ml to L to use this equation. So we have
n=0.1*0.300 where n=0.03
ΔH =
ΔH = -55733.3 J/mol
ΔH = -55.73 kJ/mol
Answer:0.03
