They are all transioning in states of matter
Answer:
5 cm³.
Explanation:
The following data were obtained from the question:
Volume of water = 35 mL
Volume of water + Rock = 40 mL
Volume of rock =.?
The volume of the rock can be obtained as follow:
Volume of rock = (Volume of water + Rock) – (Volume of water)
Volume of rock = 40 – 35
Volume of rock = 5 mL
Finally, we shall convert 5 mL to cm³. This can be obtained as illustrated below:
1 mL = 1 cm³
Therefore,
5 mL = 5 cm³
Thus, the volume of the rock is 5 cm³.
The animal with feather but cannot fly is a bird.
This is because all birds are characterized by the presence of feathers on their bodies (no mammals have feathers). However, not all birds can fly.
For example: ostriches are birds but cannot fly.
Answer: A photon of energy was released.
Explanation: The energy of the orbitals keep on increasing as the size of the orbitals keep on increasing or the value of n keeps on increasing.
The electrons absorb energy when they are irradiated or put at high temperatures and move to higher energy states. The electrons then get back to their ground state by releasing energy in the form of radiations. Thus when an electron move from n = 2 to shell n = 1, the absorbed energy is given off in form of photons of energy.
Energy is released or absorbed in the form of discrete packets of energy called as photons.
Answer: The double bonds in an aromatic ring are not fixed in position as in an alkene. The electrons are considered to be in conjugation and are delocalized around the ring.
Explanation:
Chemical compounds that have conjugated planar ring systems where there are delocalized pi-electron clouds are present in place of individual alternate and single bonds.
This means that electrons present in a double bond of alkene are in conjugation.
Therefore, we can conclude that the double bonds in an aromatic ring are not fixed in position as in an alkene. The electrons are considered to be in conjugation and are delocalized around the ring.
