Answer:
1)The molar mass of an atom is simply the mass of one mole of identical atoms. However, most of the chemical elements are found on earth not as one isotope but as a mixture of isotopes, so the atoms of one element do not all have the same mass.
2)Equally important is the fact that one mole of a substance has a mass in grams numerically equal to the formula weight of that substance. Thus, one mole of an element has a mass in grams equal to the atomic weight of that element and contains 6.02 X 1023 atoms of the element.
Nuclear fusion in the sun involves hydrogen (H) atoms
combining to form helium (He). A student claims that since the atmosphere
contains hydrogen, any fusion reaction on Earth would result in an uncontrolled
chain reaction. What is wrong in the student’s reasoning is that the uncontrolled
chain reactions can only happen during nuclear fission.
Given that
1 skvarnick = 45 quibs
3 quibs = 7 sleps
Now if we have 45 quibs it means we have you have one skvarnick
three quibs = 7 sleps
so one quib = 7/3 sleps
so 45 quibs = 7 X 45 / 3 = 105 sleps
1 --> Jaws
2 --> Four limbs
4 --> Mammary & fur
5 --> Walking on two legs
