Helium gas would be the one to effuse faster as compared to krypton. This is because krypton is heavier than helium. Heavier molecules would require more energy to move so they tend to effuse slower than molecules that are lighter which will only require less energy.
Answer:
For example, 0.9% NaCl contains 0.9 g NaCl per 100 ml of solution or 9 g NaCl/l. This can be converted to molarity by dividing by molecular weight: 0.9% NaCl = (9g/l)/(58.5g/mole) = 0.15 M NaCl.
Answer:
The seed of the blackberry will be released in the faeces of the organisms. The seed of the blackberries will be distributed to different locations. When the seed will be dropped to a favourable location, the seed will germinate and a plant will grow from it. In this way, seeds are able to be dispersed at more favourable locations via animal sources. Hence, they will have better chances of growing in different areas.
