Answer:
Number of moles = 1.57 mol
Explanation:
Given data:
Mass of propanol = 94.1 g
Molar mass of propanol = 60.1 g/mol
Number of moles of propanol = ?
Solution:
Formula:
Number of moles = mass/molar mass
by putting values,
Number of moles = 94.1 g/ 60.1 g/mol
Number of moles = 1.57 mol
The correct is answer is A, because fertilizer provides nitrogen to plants
Answer:
Test for an odor. The nonpolar substance should have a higher volatility and stronger odor because of its London dispersion forces.
Explanation:
To help Ming identify the non-polar compound, assuming the non-polar compound will have an odor test for it and most importantly, the non-polar substance should have a higher volatility due to its London dispersion forces.
- London dispersion forces are weak attractions found between non-polar molecules and noble gases.
- They account for the reason why compounds as such are volatile
According to one acid base theory the forward reaction is classified as an acid base reaction because H2S is a H donor and CH3NH2 is a H acceptor.
According to the acid base theory; an acid is the proton donor or hydrogen ions donor while the base is the proton acceptor or hydrogen ion acceptor.
Answer: Mechanical waves can be Longitudinal or Transverse.
Explanation: So... a mechanical wave is a kind of wave that is a oscillation of matter. Mechanical waves can also transfer energy. However, while it still can transfer over long distances, the wave is limited. it means that the oscillation material is limited. A mechanical wave can be a transverse wave or a longitudinal wave or a surface wave. but since there is only Longitudinal or Transverse that should be your answer.
A transverse wave, its a wave that particles move up and down.
A Longitudinal wave is a wave that moves back and forth.
