List two adaptations the cave glow worm has for capturing prey in a cave. droos a line of silk to trap palle - silk comes from glands in the mouth. a produces light to lure pret a insects are drawn towards light and get trapped in 3.
In order to calculate the yield, we first need the theoretical and actual yields since the formula is:
Percentage yield = (actual yield / theoretical yield) x 100
The theoretical yield is calculated using the reaction equation which is:
2NaNO₃ + CuCl₂ → 2NaCl + Cu(NO₃)₂
The moles of copper chloride reacting are: 31 / 134 = 0.23
So the moles of sodium chloride produced should be: 2 x 0.23 = 0.46
The mass of sodium chloride (theoretical yield) should be: 0.46 x 58 = 26.68 g
Percentage yield = (21.2 / 26.68) x 100
Percentage yield = 79.5%
Answer:
gde
Explanation:
We are attempting to synthesize 1-butyne from 1-chlorobutane. Since 1-chlorobutane is a primary alkyl halide, 1-butene is formed when 1-chlorobutane is reacted with a bulky base such as t -BuOK or t -BuOH in presence of strong heat. This is an E2 reaction.
Secondly, the 1-butene is reacted with bromine in carbon tetrachloride. The vicinal dihalide (1,2-dibromobutane) is formed. This can now undergo further elimination reactions in the presence of sodamide and strong heat to yield 1-butyne which is the desired product. These reactions involve the elimination of the first HBr molecule to give an alkenyl bromide. A second elimination now gives the terminal alkyne.
Answer:
Higher temperature = more bouncing.
So, the correct answer is that there will be less bouncing at 39 degrees F. (Lower at 39 F)
