Answer:

Yes the below choice was right! I just got a 100 on the quiz

Explanation:

Given information :

G = 173.3 KJ

H = 180.7 KJ

T = 303.0 K

S = unknown (?)

By using the given formula : G = H - TS , we can calculate the value of 'S'

On rearranging the formula we get : S = \frac{H-G}{T}

Plug in the value of G , H and T in the above formula :

S = \frac{(180.7 KJ - 173.3KJ)}{303.0K}

S = 0.02442 \frac{KJ}{K}

A pound of margarine costs $1.39. What is the cost of a kilogram of margarine
den301095 [7]

Answer:

              3.064 $

Solution:

First of all we will find the number of pounds contained by one Kg. Therefore, it is found that,

                                    1 Kilogram  = 2.20462 Pounds

Hence, as given,

                        1 Pound of Margarine costs  =  1.39 Dollars

So,

                  2.20462 Pounds Margarine will cost  =  X Dollars

Solving for X,

                     X  =  (2.20462 Pounds × 1.39 Dollars) ÷ 1 Pound

                     X =  3.064 Dollars

Potassium hydroxide, KOH, is considered a _____________ in an acid-base reaction because it ___________ a hydrogen ion to/from t
siniylev [52]
Answer: Potassium hydroxide, KOH, is considered a <u>BASE</u> in an acid-base reaction because it <u>ACCEPTS</u> a hydrogen ion from the other reactant.

According to Brønsted–Lowry acid–base theory, Base is a specie which accepts proton (H⁺) while, Acid is a specie which donate proton.

Bases
may contain a negative charge or lone pair of electrons, while, Acids contain positive charge or a neutral atom with incomplete octet.

In given statement KOH is acting as a base because it contains a negatively charged hydroxyl group which can accept proton from a acid, i.e.

                                    KOH    →     K⁺  +  OH⁻

Reaction of OH⁻ with any acid,

                         K⁺    +   OH⁻  +   HCl      →       H₂O   +   KCl

The molar heat capacity of an unknown substance is 92.1 J/mol-K. If the unknown has a molar mass of 118 g/mol, what is the speci
dlinn [17]

Answer : The specific heat (J/g-K) of this substance is, 0.780 J/g.K

Explanation :

Molar heat capacity : It is defined as the amount of heat absorbed by one mole of a substance to raise its temperature by one degree Celsius.

1 mole of substance releases heat = 92.1 J/K

As we are given, molar mass of unknown substance is, 118 g/mol that means, the mass of 1 mole of substance is, 118 g.

As, 118 g of substance releases heat = 92.1 J/K

So, 1 g of substance releases heat = \frac{92.1}{118}=0.780J/g.K

Thus, the specific heat (J/g-K) of this substance is, 0.780 J/g.K
