Answer:
Explanation:
Concentration is defined as mols of a chemical / volume. So volume tells you what the chemical is in.
There are other ways of defining concentration, but most of them have to do with units of volume in the denominator.
eg Concentration = grams / Liter
% solvent = grams or moles / amount of solvent (solvent is a volume)
I take a medication that is 5% active ingredient. That means that the solute is 5% of the solution and water (in this case) is 95% of the solution.
So in 100 mL of solution, 5 grams of the active ingredient is put in 95 grams of water.
Just as a note (and I don't care about it, but someone might), this looks like it should be in chemistry.
Answer:
4 Na + O2 = 2 Na2O
N2O5 + H2O = 2 HNO3
2 KNO3 = 2 KNO2 + O2
2 NaN3 = 2 Na + 3 N2
CH4 + 2 O2 = CO2 + 2 H2O
C6H12O6 + 6 O2 = 6 CO2 + 6 H2O
2 KCl + F2 = 2 KF + Cl2
Mg + 2 HCl = MgCl2 + H2

Answer: C
Explanation: In 1886, the Supreme Court ruled in Wabash v. Illinois that the state of Illinois could not regulate the rates that the Wabash Railroad was charging as its freight traffic was Interstate. It emphasized that only the federal government, through Congress had the power to regulate interstate commerce.
This case overturned the earlier Munn vs. Illinois case, whereby states had the power to regulate businesses dealing with interstate commerce.
The Wabash decision led to the creation of the Interstate Commerce Commission in 1887; this was the first modern regulatory agency of its kind.
Answer:
Alliie's situation best illustrates scarcity.
Explanation:
Scarcity refers to the situation when there are unlimited wants and limited resources. In the given scenario, Allie wanted to buy running shoes which cost her $90. However, her debit card was declined because she did not have enough resources (money) to pay for the shoes. Scarcity is a rather common concept which is applied all over the world because people have unlimited wants and limited resources to cover their demands.
