It’s dependent on light-dependent products ATP and NADPH which aren’t present at night
False it just makes them move faster
Answer:
36.63 Torr
Explanation:
You need to use two expressions, one for pressure and the other with the relation of density and height of the column.
For the pressure:
P = h * d * g (1)
h is height.
d density
g gravity
The second expression put a relation between the densities and height of the column so:
d1/d2 = h1/h2 (2)
let 1 be the phthalate, and 2 the mercury.
Let's calculate first the relation of density:
d1/d2 = 13.53 / 1.046 = 12.93
Now with the first expression, we can calculate the pressure so:
P = hdg
We have two compounds so,
h1d1g = h2d2g ---> gravity cancels out
From here, we can solve for h2:
h2 = h1*(d1/d2)
replacing:
h2 = 459 / 12.53
h2 = 36.63 mm
1 mmHg is 1 torr, therefore the pressure of the gas in Torr would be 36.63 Torr
1- We have to get the molar mass of calcium bromide, by getting the chemical formula ( CaBr2).
From the chemical formula, we have to get the molecular weight for each of Ca&Br on the periodic table:
Ca = 40.078 & Br = 79.904
* from the chemical formula ( CaBr2) so, the molecular weight of calcium bromide is:
40.078 + 2x(79.904) = 199.89
2- number of moles = weight / molecular weight
=20.275 / 199.89 = 0.1014 moles
3- where the volume of solution by littre = 575 mL/ 1000 = 0.575 L
So,
4-Molarity = moles of solute / L of solution
= 0.1014 / 0.575 = 0.1763 mol/L
