Answer:
The answer is the respiratory system
Explanation:
The function of the respiratory system is to move two gases. These two gases are called oxygen and carbon dioxide. Gas exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them.
Naming conventions for 2 non-metals like Si and O are based on their valence electrons, Si has 4 electrons around it and Oxygen has 6, in order for you to satisfy octet (8 electrons around each element) surrounding each Si and O, you need another O, To name these 2, just write the name of the first element which has less electrons first then the second element to which you use a prefix "di" since it means there are two oxygen, then put the names together and end the name of the second element with "ide" (remove the last 4 letters).
Silicon + "dI" + ox +"ide"
Answer:
sulphuric acid and nitric acid
Explanation:
The concentration of diluted solution is found to be 0.421 M
<u>Explanation:</u>
It is given that a stock solution (400 ml) should be diluted to 750 ml, we need to find the concentration of the diluted solution using the Law of Volumetric analysis,
V1M1 = V2M2
V1 being the volume of the stock solution = 400 ml
M1 being the molarity of the stock solution = 0.789 M
V2 being the volume of the diluted solution = 750 ml
M2 being the molarity of the diluted solution = ?
Now we have the molarity of the diluted solution by rearranging the above equation as,
M2 = 
Now plugin the values as,
M2 = 
= 0.421 M
So the molarity of diluted solution is found to be 0.421 M.
