Answer:
D. The rate decreases as reactants are used up.
Explanation:
Initially, the rate increases until the reaction is at equilibrium. At equilibrium, the rate is constant.
As the reaction progresses, the rate decreases to zero when reactants are used up ( for irriversible reactions only )
One mole of an ideal gas will occupy 22.4 liters of volume at STP.
If the only thing that changes is the pressure from 1.00 atm to 2.00 atm, then we know the initial volume, initial pressure, and final pressure. We can use Boyle's law.
Boyle's law: (initial pressure)*(initial volume) = (final pressure)*(final volume)
fill in the knowns
(1.00 atm)*(22.4 liters) = (2.00 atm)(final volume)
divide both sides by 2.00 atm
11.2 liters = final volume
Ever since antibiotics were created, man has used them to kill off bacterial infections and other illnesses. These are often overused. Just like after you get sick from a "bug" you gain a resistance against that bug, the bacteria can develop a resistance too antibiotics. There are currently strains of e-coli thats resistant to antibiotics. This means that we can't use antibiotics to kill infections.
