Answer:
The correct answer is - transparent medium.
Explanation:
A transparent substance or medium is the substance that allows light to pass through it. Light moves through these substances as they do not absorb the light and do not reflect too.
The example of such substances is glass, air or water. These substances allow light to pass through them.
Thus, The correct answer is - transparent medium.
Explanation:
if we fix the temperature, we are just left with PV = constant for the gas law. So, in this situation, if the volume is doubled, the pressure must go down by one-half. And vice-versa. The simplest illustration of this would be a cylinder with a plunger on one end: if you push the plunger in so that the volume of the cylinder is halved and the temperature remains constant, then the pressure will double.
Answer:
3.990225 grams
Explanation:
<u>Remember</u>: Morality = Moles/Liters
<u>And you are given:</u>
100 mL and 0.25
<u>what you want:</u>
Grams
SOOOO.....
convert the 100 ml to L
100 / 1000 = .1 L
now that you have Liters and Morality put it into the equation
0.25 M = Moles/ .1 L
0.25 * .1 L = .025 moles
now you take this and turn it into grams
0.025 moles / molar mass = grams
0.025 moles / 159.609 g = 3.990225 grams
Answer:
The energy for the transition of an electron from the n = 5 level to the n = 6 level of a hydrogen atom is .
Absorption is taking place.
Explanation:
where,
= energy of orbit
n = number of orbit
Z = atomic number
Energy of n = 5 in an hydrogen atom:
Energy of n = 2 in an hydrogen atom:
Energy for the transition of an electron from the n = 5 level to the n = 6 level of a hydrogen atom = E
Positive value of energy means that absorption is taking place that electron excite from lower energy level to higher energy level by absorbing the energy.
E =
The energy for the transition of an electron from the n = 5 level to the n = 6 level of a hydrogen atom is .
