Answer:

The answer of this question is , The evaporation of water through the stomata.

Explanation:

Transpiration is the process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere. Transpiration is essentially evaporation of water from plant leaves. Transpiration is important because water is needed for photosynthesis and because water cools a plant off.

Calculate the osmotic pressure (in torr) of 6.00 L of an aqueous 0.958 M solution at 30.°C, if the solute concerned is totally i

cluponka [151]

Answer: The osmotic pressure is 54307.94 Torr.

Explanation:

To calculate the concentration of solute, we use the equation for osmotic pressure, which is:

$\pi=iCRT$

where,

$\pi$ = osmotic pressure of the solution = ?

i = Van't hoff factor = 3

C = concentration of solute = 0.958 M

R = Gas constant = $62.364\text{ L Torr }mol^{-1}K^{-1}$

T = temperature of the solution = $30^oC=[30+273]K=303K$

Putting values in above equation, we get:

$\pi=3\times 0.958mol/L\times 62.364\text{ L. Torr }mol^{-1}K^{-1}\times 303K\\\\\pi=54307.94Torr$

Hence, the osmotic pressure is 54307.94 Torr.

You witnessed a slide breaking while someone is using a microscope.The silde was not dropped.You are tasked with finding out why

Evgesh-ka [11]

Answer:

See the answer below

Explanation:

The slide could have broken due to the ramming of the objective (especially the high power objectives) into the slide on the stage of the microscope while trying to bring the object on the slide into focus.

It is recommended to start with the lowest objective while trying to focus a slide. Thereafter, the next higher objective can be switched to and the image brought into focus once again. This can be repeated until the desired magnification of the image is reached.

However, at higher objective powers, the coarse adjustment knob should be avoided to avoid the objectives touching/breaking the slide. Instead, the fine adjustment knob should be used.

Hence, the breaking of the slide in the illustration could have been due to the use of the coarse adjustment knob at higher objective powers and the ramming of the objective into the slide.

Indicate whether fluorine of bromine has larger value

tensa zangetsu [6.8K]

Bromine has larger ionic radius and atomic radius than fluorine.

Fluorine has larger ionisation energy and electronegativity than bromine.

<h3>What are halogen?</h3>

Halogen are those elements that are found in group 7 of the periodic table.

Fluorine is in period two of the periodic table, meaning that it contains electrons in only the first two energy levels at ground state. It has a higher ionization energy and electronegativity than bromine.
