The answer is (1) C-14 and C-12. The life on the earth is carbon based. Carbon is important in living organisms. So C-14 and C-12 can be used to date the remains of a once-living organism.
Hello!
To answer your question lets first establish the different parts of the atom that can be affected.
Protons: Subatomic particle in the nucleus with a positive charge
Neutrons: Subatomic particle, around the same mass as the proton, with a neutral charge.
Electrons: Subatomic particle outside the nucleus with a negative charge
This particular question relates to isotopes in our elements. It's important to note that the most common/stable forms of an element are what correspond to the periodic table however they can differ in the total particles in the nucleus.
The reason they differ is because the number of neutrons (either added or removed from the nucelus) affect the isotope! Protons and electrons stay the same however as once those are removed they represent another element.
I hope this answers your question. If you need anymore clarification please ask!
Answer: These results show that the body regulates its salt and water balance not only by releasing excess sodium in urine, but by actively retaining or releasing water in urine.
Explanation:
Answer:
C
Explanation:
it is genetics of the environment
2. High tempertaure and low pressure
3. HCL,NH3,H20
4. higher collisions ieThe greater the number of gas molecules, higher will be the collision rate and hence the greater the pressure.
Explanation:
Expansion:
1. Suppose gas particles are moving in a linear fashion but if they collide with some thing they will fil that. This explains expansion theory of gases.
Fluidity: The gas molecules are in dependent of each other and have low density, they are in constant motion hence have fluidity.
low density: The gas molecules are far apart as compared to solid and liquid hence have low density.
compressibility: Due to the large distance between the gas molecules they collide with each other and vessel wall and when the space is constricted they start moving faster. They are elastic in nature.
Diffusion: Yes, because when gas is mixed it starts moving in the mixture randomly.
2. The molecules in real gas are at large distance. The high temperature and low pressure real gas would behave ideally. Because increase temperature would cause higher movement of gas particles.
3. HCL, NH3 and H2O are polar gases they will have relatively different attractive forces between them.
4. The greater the number of gas molecules, higher will be the collision rate and hence the greater the pressure.
5. The gas particles get closer, enough pressure not provided. It increases the kinetic energy as heat is produced due to compaction of molecules. The particles would not move and will become liquid causing volume to increase.
6. The gas molecules start moving rapidly, move farther apart .Volume and pressure also increases.
