Which essential oils? How much are you extracting?
Answer:
The question isn't worded properly, but if 1 or 2 are DECREASED, the frequency of collisions of specified molecules will decrease.
Explanation:
Catalysts only facilitate reaction once molecules collide. Increased temperature makes molecules move more, and thus collide more. For concentration, if there are more molecules in the same amount of room/liquid, there will be more collisions because there are more of the molecules to collide.
Answer:
A) 6.63 x 10^-34 B) 8.31 x 10^7
Explanation:
Count three from the beginning since there are no zeros and round up if you can.
Answer: 110.2 lbs
Explanation: First, let's determine how many kg the patient masses. Since the dose is 3.000 mg/kg we can convert that to 0.003000 g/kg. So
0.1500 g / 0.003000 g/kg = 50 kg.
So we know the patient has a weight of 50 kg. Now we simply multiply by 2.20462 to get lbs. So
50 kg * 2.20462 lbs/kg = 110.231 lbs
Rounding to 1 decimal place gives 110.2 lbs
It is a) a non metal.
Remember: most metals are malleable (the opposite of brittle) and conduct electricity well.
