Answer:
The number following the name of the element is the number of subatomic particles inside the nucleus of the atom. This means that it is the mass number of the isotope. The average atomic mass of the element is the sum of the products of the percentage abundance and mass number of the naturally occurring isotopes.
Since, the average atomic mass of the hydrogen is nearest to 1 then, the most abundant isotope should be hydrogen-1.
Answer:
C-O
Explanation:
you have to check the all four bonds and find out their electronegativity difference. Whichever has the largest difference, is your answer.
- N-O = 3.04 - 3.44 = -0.4
- Cl-Cl = 3.16 -3.16 = 0
- C-O = 3.44 - 2.55 = 0.89
- C-H = 2.55 - 2.20= 0.35
Now check the differences, the largest electronegativity differences means the most polar bond
Answer:
E = 16 J
Explanation:
We have,
You put scruffy can run up to 2 m/s on his fastest days scruffy has a mass of 8 kg
It is required to find the maximum kinetic energy on his fastest days. If v is the velocity, then kinetic energy is given by :
Plugging all the values,
So, the maximum kinetic energy on his fastest day is 16 J.
It is your test we can't help you if you have any homework so we can
