Since the iron is pure, we can look up its density value online and will always be true. This density value of iron is 7.87g/L. Now, we can use the density formula (D = m/V) and rearrange it to solve for V. This new equation is then V = m/D. Next, we plug in our known values and solve for V (5.00g/7.87g/L). This gives us our final answer of 0.635L (three sig figs due to the three sig figs in the provided mass).

Hope this helps!

10. What effect does temperature have on molecular motion? Using this explanation, explain why both pressure and volume can decr
vovangra [49]

Answer:

If the temperature increases the molecular movement as well, and if it increases the same it will happen with the molecular movement.

Pressure, volume and temperature are three factors that are closely related since they increase the temperature, the pressure usually decreases due to the dispersion of the molecules that can be generated, so the volume also increases.

If the temperature drops, the material becomes denser, its molecules do not collide with each other, their volume and pressure increases.

Explanation:

The pressure is related to the molecular density and the movement that these molecules have.

The movement is regulated by temperature, since if it increases, the friction and collision of the molecules also.

On the other hand, the higher the volume, the less pressure there will be on the molecules, since they are more dispersed among themselves.

(in the opposite case that the volume decreases, the pressure increases)

Why Group 18 elements on the periodic table rarely form compounds
lawyer [7]
Most elements on group 18 are the Noble Gases. They already have a complete last level with 8 electrones. Actually they can form compounds but only on the lab and they will not even last half a second.
