What does Gibbs free energy predict?

Chemistry
1 answer:
7nadin3 [17]2 years ago
5 0

Answer:

D. It predicts whether or not a reaction will be spontaneous.

Explanation:

<em>What does Gibbs free energy (ΔG) predict? .</em>

A. It predicts what the rate of the reaction will be. NO. ΔG is a thermodynamical parameter and it is not related to the kinetics of the reaction.

B. It predicts how high the activation energy is. NO. ΔG is a thermodynamical parameter and it is not related to the kinetics of the reaction.

C. It predicts if entropy will increase or decrease. NO. ΔG depends on the entropy but not the other way around.

D. It predicts whether or not a reaction will be spontaneous. YES. If ΔG < 0 the reaction is spontaneous and if ΔG > 0 the reaction is not spontaneous.

A graduated cylinder is filled 25.0 mL with water and a piece of granite is placed in the cylinder, displacing the level to 37.2
kvv77 [185]

The volume  of the granite piece  in Cm³  is 12.2 cm³

 <u><em>calculation</em></u>

volume of granite = (volume of cylinder after placing granite - volume  of  cylinder  before  placing  granite

 = 37.2 ml - 25.0 ml = 12.2 ml


convert ml  to Cm³

that is 1 ml = 1 cm³

       12.2 ml =  ? cm³

<em>by cross  multiplication</em>

=(12.2 ml x 1 cm³) / 1 ml = 12.2 cm³

Which gas has approximately the same density as c2h6 at stp no nh3 h20 so2?
zmey [24]
1 mole of any gas occupy 22.4 L at STP (standard temperature and pressure, 0°C and 1 atm).

Let given gases be 1 mole. So their volumes will be the same, 22.4 liters.

Density is the ratio of mass to volume.

By formula; density= mass/volume; d=m/V

To find out masses of gases, do the mole calculation.

By formula; mole= mass/molar mass; n= m/M; m= n*M

Molar masses are calculated as
1. C₂H₆ (ethane)                 = 2*12 g/mol + 6*1 g/mol= 30 g/mol
2. NO (nitrogen monoxide) = 1*14 g/mol + 1*16 g/mol= 30 g/mol
3. NH₃ (ammonia)              = 1*14 g/mol + 3*1 g/mol= 17 g/mol
4. H₂O (water)                    = 2*1 g/mol + 1*16 g/mol= 18 g/mol
5. SO₂ (sulfur dioxide)        = 1*32 g/mol + 2*16 g/mol= 64 g/mol
Use Periodic Table to get atomic mass of elements.

Since their volumes are equal, compounds having the same molar mass will have the same density. 
Recall the formula d= m/V.

Ethane and nitrogen monoxide have the same density.

The answer is C₂H₆ and NO.

Suppose that you want to compare the mass of a block of ice to its mass as liquid
Morgarella [4.7K]

Answer:

You will find the mass of the pan and water but if the water got to its boiling temperature that mass may be a little bit off seeing as some of it may have evaporated
