What's the relationship between total and partial pressure? The total pressure is the sum of the parcial pressures!
So for us, it would be:
378= 212+101+x
where x is the parcial pressure of nitrogen.
Now we count:
378= 212+101+x
378=313+x
378-313=x
65=x
So the parcial pressure exerted by nitrogen is 65!
The state of matter with a specific volume but no definite shape is the <u>Liquid</u> state.
<u>Explanation:</u>
There are three states of matter according to chemical science: Solid, Liquid and Gas. There is not much space in among the molecules. The particles in a liquid are free to float, so while a liquid has a certain volume it has no definite form. Liquids are composed of atoms or molecules bound by inter molecular bonds.
Most of the liquids resist compression while some do not, unlike a gas, a liquid will not spread to fill any container room and will retain a fairly constant density. A characteristic liquid state property is surface tension that results to wetting phenomena. Water is perhaps the most frequent substance on Earth.
<span>A SI base unit is the single and direct measurement unit for a physical entity. E.g. For mass it is kg, for time it is sec, A derived unit is determined by a physical equation with the base units, like for velocity equals distance divided by time, in SI units: unit of v (velocity)= m (meter) divided by sec (seconds).

Carbonated drinks are a mixture of many compounds such as glucose(sugar) and others, while water is simply its own molecule.
Answer:
See the answer below.
Explanation:
Fire has three major components:
- Heat
- Smoke
- Gases ( in form of CO, CO2 etc)
If the victim had died as a result of the fire, he/he would have inhaled smoke and hot gases from the fire. These components would have resulted in traces of burns and soot deposition in the trachea and lungs as well as traces of CO in the blood of the victim.
If the analysis of the victim's corpse does not reflect some of the results above, it can be effectively concluded that the victim has been dead before the fire.
<em>The single most important indicator of death by the fire would be the presence of CO in the blood of the victim's corpse. All others might be to a less significant degrees.</em>
