Answer:
When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.
hope this helps!!!!!!
Basically, the answer for this would be N or NITROGEN. If we combine nitrogen with chlorine, what happens is that, it can attract more chlorine electrons towards itself. The reason is that, nitrogen is considered more electronegative compared to chlorine. So best answer for this is the first option.
Answer:
156.8kPa
Explanation:
The problem here is to convert mmHg to kPa;
We have been given:
1176mmHg and the problem is to convert to kPa;
1000Pa = 1kPa
1 mmHg = 133.322Pa
1176mmHg will give 1176 x 133.322 = 156787.1Pa
To kPa;
156.8kPa
