Answer:
As there are many units of mass and volume covering many different magnitudes there are a large number of units for mass density in use. The SI unit of kilogram per cubic metre (kg/m3) and the cgs unit of gram per cubic centimetre (g/cm3) are probably the most commonly used units for density.
Explanation:
Based on the data given of the bonds listed below, the weakest bond is C-H and the strongest bond is C ≡ C.
A strong bond is a stable bond.
<h3>Which of the bonds listed is the weakest and which is the strongest?</h3>
The strength of a bond is proportional to the amount of energy required to break or form the bond.
A weak bond will require less energy to form than a strong bond.
A weak bond is unstable while a strong bond is stable.
Data provided:
839 kJ/mol C ≡ C
495 kJ/mo O = O
413 kJ/mo C—H
From the data given of the bonds listed below, the weakest bond is C-H and the strongest bond is C ≡ C.
A strong bond is a stable bond.

Answer: Correct options are as follows.
- salt is not chemically bonded to water.
- salt and water retain their own chemical properties.
Explanation:
When salt is dissolved in water then it means that it is a physical change as salt has completely dissociated into ions but they are not chemically combined to the water molecules.
As a result, both salt and water will retain their chemical properties.
For example, NaCl when dissolved in water will dissociate as follows.
Only the particles of salt have evenly distributed in water.
And, when a components of a salt chemically combine with another substance then it will form a new compound.
Therefore, we can conclude that salt dissolved in water is a solution, therefore:
- salt is not chemically bonded to water.
- salt and water retain their own chemical properties.
I think the correct answer from the choices listed above is option B. When a substance changes from one phase to another, the average kinetic energy of the substance <span>changes since the molecules movements are changed as well. Hope this answers the question. Have a nice day.</span>
Answer:
1. Wildlife
2. Seafood
Explanation:
1. Wildlife refers to the species which are not domesticated by the humans and they live as a wild organisms in the areas which are not interfered with the humans. In the given question, the wild creatures that live on the land therefore are considered a part of the wildlife.
2. Seafood refers to the species which are considered as food which humans get from the sea. In the given question, the Blue Fin fishes are considered a seafood therefore.
