Hi my dear friend,

The statement that explain how ATP and its phosphate groups are related to energy used in plant process is that ADP gains a phosphate to create ATP, which stores energy for making sugars. These packets of energy in the form of ATP are then broken down to release energy and use that energy in synthesis of glucose.

~Thank you

Step2247 [10]

The main precautions to take if a gas cylinder sign is present in the lab visually check that the gas cylinder is restrained, but keep a safe distance from it. The correct option is c.

<h3>What are the precautions?</h3>

Precautions are the preventive steps that are taken to save yourself from any dangerous circumstances. These steps are always taken in doing experiments and other scientific procedures.

Here, the precautions are to check the gas cylinder.

Thus, the correct option is c, Visually check that the gas cylinder is restrained, but keep a safe distance from it.

Match the following aqueous solutions with the appropriate letter from the column on the right. Assume complete dissociation of

Serhud [2]

Answer: 0.17 m $CH_3COONH_4$ : Highest freezing point

0.20 m $CoSO_4$ : Second lowest freezing point

0.18 m $MnSO_4$ : Third lowest freezing point

0.42 m ethylene glycol: Lowest freezing point

Explanation:

Depression in freezing point is a colligative property which depend upon the amount of the solute.

$\Delta T_f=i\times k_f\times m$

where,

$\Delta T_f$ = change in freezing point

i= vant hoff factor

$k_f$ = freezing point constant

m = molality

a) 0.17 m $CH_3COONH_4$

For electrolytes undergoing complete dissociation, vant hoff factor is equal to the number of ions it produce. Thus i =2 for $CH_3COONH_4$ , thus total concentration will be 0.34 m

b) 0.18 m $MnSO_4$

For electrolytes undergoing complete dissociation, vant hoff factor is equal to the number of ions it produce. Thus i = 2 for $MnSO_4$ , thus total concentration will be 0.36 m

c) 0.20 m $CoSO_4$

For electrolytes undergoing complete dissociation, vant hoff factor is equal to the number of ions it produce. Thus i = 2 for $CoSO_4$ , thus total concentration will be 0.40 m

d) 0.42 m ethylene glycol

For non electrolytes undergoing no dissociation, vant hoff factor is equal to 1 . Thus i = 1 for ethylene glycol, thus concentration will be 0.42 m

The more is the concentration, the highest will be depression in freezing point and thus lowest will be freezing point.
