Condensation is the process of conversion of a substance present in vapor state to to liquid state. Clouds are formed when water vapor present in air condenses and changes from vapor to liquid state. The fast moving, energetic water molecules present in the vapor state, when encounter a cooler surface slow down during condensation and come closer to form a liquid.

So the correct answer will be,

A. molecules come closer and stick to each other.

Condensation is conversion of vapours to liquid

in vapour the molecules of water are far from each other and can move here and there. When a liquid like water condense the molecules come closer to each other.

Thus come closer together and stick to each other.

A critical reaction in the production of energy to do work or drive chemical reactions in biological systems is the hydrolysis o

MAVERICK [17]

Answer : The value of $\Delta G_{rxn}$ is -49.6 kJ/mol

Explanation :

First we have to calculate the reaction quotient.

Reaction quotient (Q) : It is defined as the measurement of the relative amounts of products and reactants present during a reaction at a particular time.

The given balanced chemical reaction is,

$ATP(aq)+H_2O(l)\rightarrow ADP(aq)+HPO_4^{2-}(aq)$

The expression for reaction quotient will be :

$Q=\frac{[ADP][HPO_4^{2-}]}{[ATP]}$

In this expression, only gaseous or aqueous states are includes and pure liquid or solid states are omitted.

Given:

$[ATP]$ = 5.0 mM

$[ADP]$ = 0.60 mM

$[HPO_4^{2-}]$ = 5.0 mM

Now put all the given values in this expression, we get

$Q=\frac{(0.60)\times (5.0)}{(5.0)}=0.60mM=0.60\times 10^{-3}M$

Now we have to calculate the value of $\Delta G_{rxn}$ .

The formula used for $\Delta G_{rxn}$ is:

$\Delta G_{rxn}=\Delta G^o+RT\ln Q$ ............(1)

where,

$\Delta G_{rxn}$ = Gibbs free energy for the reaction = ?

$\Delta G_^o$ = standard Gibbs free energy = -30.5 kJ/mol

R = gas constant = $8.314\times 10^{-3}kJ/mole.K$

T = temperature = $37.0^oC=273+37.0=310K$

Q = reaction quotient = $0.60\times 10^{-3}$

Now put all the given values in the above formula 1, we get:

$\Delta G_{rxn}=(-30.5kJ/mol)+[(8.314\times 10^{-3}kJ/mole.K)\times (310K)\times \ln (0.60\times 10^{-3})$

$\Delta G_{rxn}=-49.6kJ/mol$

Therefore, the value of $\Delta G_{rxn}$ is -49.6 kJ/mol

Which two of the four quantum numbers determine the energy level of an orbital in a multielectron atom? Which two of the four qu

Roman55 [17]

Answer:

The correct answer is - n and l.

Explanation:

The size of an orbital is determined by the principal number of shell which is represented by n. The larger the energy level (n) bigger the size of the orbital. N can be any integer value: 1, 2, 3 . . . . and so on.

l represents the angular momentum or subshell number provides the overall shape of an orbital in this subshell only integer values between 0 and n-1 are permitted.

Thus, n & l are two quantum numbers that determine the energy level of an orbital in a multielectron atom.

No pressure but anyone who can answer these is a genius. (Please fill in the question mark)

disa [49]

use variable

1K₂MnF₆ + aSbF₅⇒ bKSbF₆ + cMnF₃ + dF₂

K, left=2,right=b⇒b=2

Mn, left=1, right=c⇒c=1

Sb, left=a, right=b⇒a=b=2

F, left=6.1+5a, right=6b+3c+2d

equation:

6+5(2) = 6(2)+3(1)+2d

16=15+2d

1=2d

d=0.5

So the reaction equation becomes:

1K₂MnF₆ + 2SbF₅⇒ 2KSbF₆ + 1MnF₃ + 0.5F₂ x2

2K₂MnF₆ + 4SbF₅⇒ 4KSbF₆ + 2MnF₃ + F₂
