Answer:
The mass number of an isotope is the sum of neutrons and protons.
Explanation:
In any elemental isotope, the only things that will affect molar mass and mass number is the number of protons and neutrons. Electrons are not counted because we usually assume they are equal to the amount of protons and have no weight.
Protons are what gives the element its atomic number and the neutrons determine the type of isotope it is within the element.
For instance:
There can be a regular Carbon - 12
But there are isotopes like Carbon - 13 and Carbon - 14.
*The number of protons stays the same but the number of neutrons are different
Answer:
Dissolved oxygen levels are increased by supplementing wind and wave action, adding plants to water and exposing water to purified oxygen. Also removing fish could increase the amount of dissolved oxygen
Explanation:
Lipids are insoluble in water and they produce twice as more energy as carbohydrates.
Answer:
I say the 1st one I'm so terrible sorry if I'm wrong
Explanation:
Water can take many forms. At low temperatures (below 0°C), it is a solid. When at “normal” temperatures (between 0°C and 100°C), it is a liquid. While at temperatures above 100°C, water is a gas (steam).
The state the water is in depends upon the temperature. Each state (solid, liquid, and gas) has its own unique set of physical properties.
