Answer:
have the same number of atoms
Explanation:
Atoms of the same element have the same atomic number so the number of protons (and electrons) are same. But they have same or different mass number (like that for isotopes) . Different mass number will have different number of neutrons.
Answer:
A- Speed = distance/time
Explanation:
Would make sense and that's what I remember
The nucleus is made of protons and neutrons
Answer:
1. 7.0984 mmHg
2. 7.0984 torr
Explanation:
Data obtained from the question include:
Partial Pressure of Ar = 0.00934 atm
1. The value of pressure in mmHg is obtained as shown below:
1 atm = 760mmHg
Therefore, 0.00934 atm = 0.00934 x 760 = 7.0984mmHg
2. The value of the pressure in torr is obtained as shown below:
1 atm = 760torr
Therefore, 0.00934 atm = 0.00934 x 760 = 7.0984torr
Answer:
50%
Explanation:
You would have to do 15 divided by 30 x 100 to get 50
Percentage Yield = Actual Yield divided by Theoretical Yield
Hope this is right and helpful
