Chemistry
1 answer:
scoundrel [369]3 years ago

Answer:

protons

These particles do not vary in quality from one element to another; rather, what gives an element its distinctive identification is the quantity of its protons, called its atomic number. Protons and neutrons contribute nearly all of an atom's mass; the number of protons and neutrons is an element's mass number

Which of the following leads to a higher rate of diffusion?
tiny-mole [99]
<h3><u>Answer;</u></h3>

Higher velocity of particles

<h3><u>Explanation;</u></h3>

The diffusion rate is determined by a variety of factors which includes;

  • Temperature such that the higher the temperature, the more kinetic energy the particles will have, so they will move and mix more quickly and the diffusion rate will be high.
  • Concentration gradient such that the greater the difference in concentration, the quicker the rate of diffusion.
  • Higher velocity of particles increases the diffusion rate as this means more kinetic energy by the particles and hence the particles will mix and move faster, thus higher diffusion rate.

If the atomic number of an element is 9 and the mass number is 19, how many neutrons does the atom have? 10 9 19 28 1 points
IRINA_888 [86]
Remember....

mass number= atomic number + number of neutrons

If the mass number is 19 and the atomic number is 9, then the number of neutrons is 19-9 which is 10.
