Answer:
The sum of the protons and neutrons.
Explanation:
protons + neutrons = atomic mass
Answer:
both
Explanation:
Carbon in the air around the living thing is moving in and out of its lungs. The movement is occurring at the same time. This is one of the most important gaseous exchange important to life.
- The goats takes in oxygen gas from the surrounding and releases carbon dioxide in the process.
- But, air is actually drawn in by the goat which is a mixture of several gases.
- Air contains carbon dioxide which is a rich source of carbon
- With the carbon dioxide from respiratory processes, the goat ejects and breathes out this waste carbon matter.
- Therefore, the gaseous exchange in a goat involves the movement of carbon in and out of the air.
I believe is different in pressure
Answer: By understanding conversion factors and how they are related to each other
Explanation:
Dimensional Analysis is a step by step approach to solving problems in Physics, Chemistry , and Mathematics. It involves having a clear knowledge and understanding to be able to convert a given unit to another in the same dimension using conversion factors and knowing how they are related to each other.
For instance, In Chemistry, we want to Convert 120mL to L.(note that ml stands for millilitres and ;L stands for litres)
Or first approach will be to write out the conversion factor related to our problem which is
1000ml =1L
such that 120ml = (we cross multiply))
giving us 120ml x 1L/1000ml =0.12L
This same process is applied to convert any type of dimensional analysis problems be it physics or mathematics.
Potassium is not found free in nature but is found in the form of potash. Potash is the ore of potassium and this ore is mined from deep down the earth or can sometimes be found on the surface. Potash was mostly formed as sea water receded and left deposits.
Potash is usually in the form of potassium salts such potassium chloride and potassium sulphate. The potash is mined then taken to the factory where it is crushed and purified by removing such impurities as clay.
The now purified potassium salts are subjected to a process called electrolysis where potassium metal is obtained from its salt.
