Answer:
1. A. True
2. A. True
3. B. False
4. A. True
5. B. False
Explanation:
1. The particles are in constant motion. The collisions of the particles with the walls of the container are the cause of the pressure exerted by the gas. A. True. The pressure of an ideal gas is higher than the one that would exert a real gas.
2. The particles are assumed to exert no forces on each other; they are assumed neither to attract nor to repel each other. A. True. The intermolecular forces are negligible.
3. The particles are so small compared with the distances between them that the volume of the individual particles can be assumed to be about 1 mL. B. False. The volume of the gas particles is negligible.
4. The molecules in a real gas have finite volumes and do exert forces on each other, thus real gases do not conform to some of the assumptions of an ideal gas as stated by the kinetic molecular theory. A. True. We cannot apply ideal gas laws to real gases.
5. The average kinetic energy of a collection of gas particles is assumed to be inversely proportional to the Kelvin temperature of the gas. B. False. The average kinetic energy of a collection of gas particles is assumed to be directly proportional to the Kelvin temperature of the gas.
<span>The reaction rate increases.
Why </span><span>Well a catalyst usually lower the activation barrier in an energy diagram. The lower and smaller that gap means the reaction is taking place rapidly compared to when that activation barrier gap is higher. </span>
Answer:
Explanation:
Spectator ions are defined as the ions which does not get involved in a chemical equation or they are ions which are found on both the sides of the chemical reaction present in ionic form.
The given chemical equation is:
The complete ionic equation is;
The ions which are present on both the sides of the equation are
and
and are not involved in net ionic equation.
Hence, the net ionic equation is :
It mostly begins in the cytoplasm, but most of the reactions occur in the cell mitochondria.
Hope this helps, if not, comment below please!!!!
Explanation:
The idea behind using fossils to correlate two land masses was first put into limelight by a British geologist, Williams Smith.
According to the principle of fossil and fauna succession "fossils and fauna succeed one another in a define order".
This implies organisms evolve in predictable manner.
Since we know that certain types of organisms live within a period in time on the earth surface, we expect that such organisms would be fossilized in the geologic record and preserved.
- Identify the fossil record in one part of the land mass. Log the rock types with the corresponding fossils in them.
- On the other side, repeat the same process.
- Look for unconformity surfaces where some part of the stratigraphic records might have been lost.
- If the fossil records on one side corresponds with that on the other other side, it suggests that the land masses must have once been joined together.
- The logic is that when the organism were on the same land mass, they thrived and lived together.
- They became fossilized together till the lands separated.
