<u>Answer:</u> The volume of stock solution needed is 0.016 L
<u>Explanation:</u>
To calculate the volume of stock solution, we use the equation:
where,
are the molarity and volume of the stock solution
are the molarity and volume of diluted solution
We are given:
Putting values in above equation, we get:
Hence, the volume of stock solution needed is 0.016 L
<em>Question : Where does crude oil come from?</em>
<em>So firstly Crude oil is a fossil fuel and,is know and called implies, Over time the fossils the remains of vegetation and various organisms, and bacteria and algae, are covered by an increasing amount of soil before they are converted through heat and pressure into matter composed largely of hydrocarbons.</em>
<em>Hopefully that helps you ! have a good day !</em>
First you need to know how ionic compounds are created!
Ionic compounds are formed by IONS (Obviously, what am I, a dummy?)
There are two types of ions: anions and cations.
Anions can only be formed by nonmetals, and cations can only be formed by metals.
In order for ions to bond, there must be one anion and one cation, because opposite charges attract.
Let's look at your choices.
1) Ca + Br can form ionic bonds
2) Na + F can form ionic bonds
3) Li + Cl can form ionic bonds
However...
4) Mg + Ar
This is a special case. Ar is a NOBLE GAS, which means that it has the maximum number of valence electrons (8) in its outermost shell. Therefore, ANY type of bonding is IMPOSSIBLE.
Your answer should be 4) Mg + Ar
Answer: well because
they have a different mass but the triangles have all the same acceleration the house is going to have more force added to it.
