1.6456 x 10^3 (ten to the third power)
Answer:
ions
Explanation:
atoms because of the charge
Answer:
Limited
Explanation:
For competition to exist within a population or between population, shared or common resources that organisms holds very important must be very limited and scared.
Competition is a struggle between organisms for limited resources in the ecosystem.
- It is an interaction between organisms in which one of them is harmed.
- Competition originates from limited supply of shared or mutual resources among organisms.
- When competition is between organisms from different population, it is called an interspecific competition.
- Competition between organisms within the same population, i.e of the same species is intraspecific competition.
Answer:
28.93 g/mol
Explanation:
This is an extension of Graham's Law of Effusion where 
We're only talking about molar mass and time (t) here so we'll just concentrate on 
. Notice how the molar mass and time are on the same position, recall effusion is when gas escapes from a container through a small hole. The time it takes it to leave depends on the molar mass. If the gas is heavy, like Xe, it would take a longer time (4.83 minutes). If it was light it would leave in less time, that gives us somewhat an idea what our element could be, we know that it's atleast an element before Xenon.
Let's plug everything in and solve for M2. I chose M2 to be the unknown here because it's easier to have it basically as a whole number already.
The square root is easier to deal with if you take it out in the first step, so let's remove it by squaring each side by 2, the opposite of square root essentially.
M2= 0.22 x 131
M2= 28.93 g/mol
