Answer: In the gas phase using the example of the perfume in the air, the air very slowly separates the molecules of the perfume which allow them to spread to the olfactory system (sense of smell) to the individuals in the area. In this experiment, the particles moved very slow and we know this because it took a long time for the perfume smell to reach the back of the room. In the liquid phase using the example of the food dye in the cold and hot water, the food dye diffused a lot faster in the hot water because the particles were moving a lot faster and colliding more often and at an increased rate compared to the cold water where the food dye took a lot longer to diffuse in the water and the particle motion and collision was a lot slower and a lot less frequent
Explanation:
Looked it up.
Answer:
NaOH
Explanation:
Looking at a periodic table, sodium is Na, oxygen is O and hydrogen is H
If we have a compound containing 1 atom of sodium (Na), 1 atom of oxygen(O) and 1 atom of hydrogen(H) the formula would be NaOH
3.2 x10000000
the correct answer is 3.2x 10⁷
Answer:
Cl
Explanation:
⁴¹Ca has an atomic number equal to 20, it means that it has 20 protons and 20 electrons ad its neutral state. In the decay by electron capture, it will lose one electron and will become a cation, but the mass (41) and the atomic number will remain the same.
When Ca⁺ undergoes alpha decay, it will lose an alpha particle, which has mass 4 and 2 protons.
⁴¹₂₀Ca⁺ → ³⁷₁₈X⁺ + ⁴₂α
To be stable, X will lose a proton and will become ³⁷₁₇X. The element which has atomic number 17 is chlorine, Cl.
