6 0

1 In the beginning God created the heavens and the earth.

2 Now the earth was formless and empty.darkness was over the surface of deep and the spirt of the God was hovering over the waters.

3 and God said let there be light, and there was light.

4 God saw the light was good and seperated the light from darkness.

5 God called the light day and the darkness night and there was evinigining and there was morning of the first day.

6 And God said let there be an expanse of water between the waters to separate water from water.
So god made the expanse and separated the water under the expanse from the water above it and it was so.
7 God called the expanse sky .and there was evening and there was morning the second day.
There that how the atmosphere was made.and that what geologist know too

How are density and state of matter related to the physical properties of a substance?

Artemon [7]

Answer:

Density by giving the object it's weight/volume. State of matter by giving its chemical substances and physical shape.

Explanation:

State of matter, (solid, liquid, or a gas) determines the main physical property of a substance. If it's a liquid, it would have an indefinite shape/physical appearance. If the object is a solid than the shape would have a definite shape/physical appearance. Density is defined as mass per volume which means the weight of an object divided by the volume determines the density of the object. You would have the volume (the amount of space an object takes up) and the mass (weight of the object) if you have the objects density.

To conclude, both density and the objects state of matter determine the physical properties of a substance. "Density the weight and volume, and the state of matter is the shape/chemical properties of the substance."

Hope this helps.

1: At which temperature would a reaction withΔH = -102 kJ/mol, ΔS = -0.188 kJ/(mol×K) be spontaneous? 2: At which temperature wo

Naddik [55]

Answer:

1: At temperatures below 542.55 K

2: At temperatures above 660 K

Explanation:

Hello there!

In this case, according to the thermodynamic definition of the Gibbs free energy, it is possible to write the following expression:

$\Delta G=\Delta H-T\Delta S$

Whereas ΔG=0 for the spontaneous transition. In such a way, we proceed as follows:

$0=\Delta H-T\Delta S\\\\T=\frac{-102kJ/mol}{-0.188kJ/mol-K} \\\\T=542.55K$

It means that at temperatures lower than 542.55 K the reaction will be spontaneous.

$0=\Delta H-T\Delta S\\\\T=\frac{132kJ/mol}{0.200kJ/mol-K} \\\\T=660K$

It means that at temperatures higher than 660 K the reaction will be spontaneous.

Best regards!

VashaNatasha [74]

Answer:

It corresponds to Charles' Law

Explanation:

Charles's Law corresponds to one of the gas laws, where temperature and volume are related, to constant pressure. That is, according to said equation, the volume of a gas varies directly with the temperature, under conditions of constant pressure.
