In a gas molecules have to scatter off molecules to exchange energy in larger distances, so the probability of transfer is much smaller. Air is a bad conductor because, to conduct heat current molecules should absorb heat and transmit it to neighbor by vibrating.
Basic radicals (cations) have been divided into groups based on Ksp values
Answer:
E.
Explanation:
Look at change in concentration over time...is it increasing or decreasing? It is increasing right as you can see because it starts at 0 then increases and plataeus. What increases in a reaction, reactant or product? Products increase right cuz your reactants react with each other to make prodcuts.
At start of reaction you have no products (zero) thus this graph starts at 0. At end you have alot of product thus over time the concentration of product increases.
ABC are reactants their concentration should decrease over time
DE are products, they should increase as reaction goes on.
Explanation:
The scientific notation:
where
and k is integer.
We have the example:
You can write the numbers in a "normal" form:
Make the sum:
And next write it in the scientific notation:
<h3>Other method:</h3>
You can add numbers in scientific notation if the power of tens in both number is the same.
Therefore you must convert the first number:
Now, you can make the sum:
