Explanation:
B. The population of rabbits will increase.
Answer:
A drug administered at a rate of 13.5 cL/hour has a rate in μL/s of 37.5 μL/s
Explanation:
The given rate at which the blood is administered = 13.5 cL/hour
The rate at which the question asked to be administered = μL/s
The conversion factor between cL and μL is given as follows;
1 cL = 10,000 μL
Which gives;
13.5 cL/hour × 10,000 μL/cL × 1 hour/(60 × 60 seconds) = 37.5 μL/s
Therefore, a drug administered at a rate of 13.5 cL/hour has an administration rate of 37.5 μL/s.
Answer:
alkali metals: 1 valence electron, very reactive metals
alkaline earth metals: 2 valence electrons, reactive metals
halogens: 7 valence electrons, very reactive nonmetals
noble gases: 8 valence electrons, very little reactivity
Explanation:
The groups increase by 1 valence electron as you move from left to right across the periodic table, skipping over the transition metals. The closer an element is to having a full octet of 8 valence electrons, the more reactive it will be. The alkali metals and halogens are both just 1 away from an octet -- alkali lose an electron, halogens gain one. This makes them very reactive.
Answer:
w = 0.325 g aspirin does it contain
Explanation:
⇒ w =325 mg aspirin * ( 0.001g / mg)
⇒ w = 0.325 g aspirin
All are equal.
One mole represents a fixed number. Since they all have one mole of molecules, they all have the same number of molecules.
