The average atomic mass of the element is the weighted average atomic mass of element with respect to the natural abundance of all the isotopes.
isotopes are atoms of the same elements with different mass numbers , in other words same number of protons but different numbers of neutrons.
to find the average atomic mass we need to know the atomic masses of all the isotopes in addition to the natural abundance percentages of the isotopes.
answer is we need to know the atomic masses of the isotopes as well
Answer:
b. Its concentration is half that of the chloride ion
Explanation:
As the calcium chloride formula is CaCl2
CaCl2 <--> Ca + 2 Cl-
Answer:
it's a measure of how far down light can penetrate through the water column. ... Because water clarity is closely related to light penetration, it has important implications for the diversity and productivity of aquatic life that a system can support
Answer: 4.8 grams of hydrogen is 2.4 moles, and 38.4 grams of oxygen is 1.2 moles. This is exactly the Stoichiometry ratio of the reaction, therefore the two will both completely react giving rise to the same total mass of water.
Answer:
Sample Response: Seeds travel in several different ways. They can travel in the wind, like a dandelion does, or in water, like a coconut does. Seeds also travel with the help of animals. For example, squirrels collect and hide nuts, while birds carry seeds on their beaks or feet. Birds also eat seeds and drop them in a new location. Some seeds get stuck on animal fur or on people’s clothing.
