The pressure exerted by a gas on its container is directly proportional to the mass of the individual gas molecules.
Gas law states that the pressure exerted by a gas on its container is directly proportional to its absolute temperature (Kelvin temperature) and number of moles of the gas.
PV = nRT
where;
P is the pressure of the gasV is the volume of the gasR is the gas constantT is the absolute temperature of the gasn is number of gas moles[tex]number \ of \ moles = \frac{\ reacting \ mass \ of \ individual \ gas}{molecular \ mass}= \frac{m}{M}[/tex]
[tex]PV = \frac{m}{M} RT[/tex]
Thus, the pressure exerted by a gas on its container is directly proportional to the mass of the individual gas molecules.

what is the difference between cyclic compound and straight chain compound in hydrocarbons reaction
Explanation:
Cyclic Hydrocarbons
A cyclic hydrocarbon is a hydrocarbon in which the carbon chain joins to itself in a ring. A cycloalkane is a cyclic hydrocarbon in which all of the carbon-carbon bonds are single bonds. Like other alkanes, cycloalkanes are saturated compounds. Cycloalkanes have the general formula CnH2nCnH2n. The simplest cycloalkane is cyclopropane, a three-carbon ring.

Answer:
So, the melting of wax and vapourisation of melted wax are physical changes. Chemical Changes : The wax near flame burns and gives new substances like carbon dioxide, carbon soot, water vapour, heat and light. LPG is another example of a familiar process in which both the chemical and physical changes take place.
What did Fermi mean when he said, "The reaction is self-sustaining"?
The reaction reached critical mass.
A spontaneous chain reaction had been accomplished.
The nuclear reaction was out of control.
The nuclear reaction could be controlled and maintained.
Answer:
The nuclear reaction could be controlled and maintained.
Explanation:
People had initiated a self-sustaining nuclear reaction--and then stopped it. He had released the energy of the atom's nucleus and controlled that energy.
Fermi's achievement in setting off the first self-sustaining nuclear chain reaction from his design of an atomic pile led to a new Age of the Atom. The controlled release of nuclear energy was now a reality

Due to the fact that electrons are delocalized in graphite, it is a good conductor of electricity. Carbon atoms in graphite form hexagonal layers and are in covalent bonds with three other carbon atoms. Due to this non-bond electron configuration, each carbon atom conducts electricity in the form of a delocalized electron.

O Solid
O Liquid
Gas
O None of the above
Answer:
Solid
Explanation:
According to Wikipedia
Deposition is the phase transition in which gas transforms into solid without passing through the liquid phase. Deposition is a thermodynamic process. The reverse of deposition is sublimation and hence sometimes deposition is called desublimation.
1) Is a moth bursting out of cocoon a chemical or physical change? (I put chemistry because i didn't know what else to put) 2) Is playing with purple and green slime chemical or physical change
Answer:
1)A moth bursting out of a cocoon is neither a chemical or physical change, it's a biological change. If I had to chose it would be a physical change though. Not to sure...
2)Playing with slime is a physical change.
Explanation:
1)The reason why I would chose physical change is because the moth is changing it's physical state more than it's chemical composition, but you should say both if that's an option.
2)A physical change is when the temperature, shape, or state of matter changes. A chemical change occurs when the actual substance changes. An example of this is a chemical reaction. Because the slime is changing shape and not substances, I would say that it's obviously a physical change.

volume= mass/density
you have a volume- 8.33cm3
you have a density- 2.07 g/cm3
Answer:
8.33cm3 * 2.07g/cm3= 17.24g
