Answer:
A and B as well C are the compounds.
Explanation:
- A seems to be a compound, very least, it appears to contain carbon and oxygen.
- C seems to be a compound, containing respectively oxygen as well as carbon.
- B isn't always described by that of the information provided, it is therefore presumably a compound because there are few components as white solid particles.
So that the above is the correct answer.
As we know that 760 mmHg is equal to 1 atm.
So,
If 760 mmHg is equal to = 1 atm
Then
738 mmHg will be equal to = X atm
Solving for X,
X = (738 mmHg × 1 atm) ÷ 760 mmHg
X = 0.971 atm
Result:
738 mmHg is equal to 0.971 atm.
Explanation:
99 is not a prime number because it can be multiplied by itself and by other numbers
99*1
9*11
A neutral atom of potassium has 19 electrons.
Answer: Option B) Pure Substance &
Compound
Explanation:
Carbon dioxide is a compound because it is formed when one carbon atom and two oxygen atoms chemically combined together.
C(s) + O2(g) ---> CO2(g)
Also, CO2 is a pure substance because it is natural and cannot be broken down easily or separated by physical methods.
