Answer:
1) False
2) there are equal amounts of rectants and products
Explanation:
1) When dynamic equilibrium is achieved. the rate of forward and backward reaction they are the same, that is to say, two opposite reactions occur at the same rate, keeping the concentrations constant over time. Different to say the rate of the ractions go to zero.
2) A chemical equilibium exists when what is produce in quantities is equal to what reacts.
So the correct answer is the literal (d).
Isotopes are forms of the same elements which contain equal number of protons but different number of nucleus in their nuclei, thus the differ in relative atomic mass but they have same chemical properties. The mass number is the summation of number of proton and number of neutron of an atom. If the mass number is known, then one need to know the number of proton in the atom in order to calculate for the number of neutron.
Gosh, I love chem!
[H2O]/t should be 0.085M/s
this is because of the coefficients in front of H2S and H2O being the same.
the significance of this answer is that the H2S disappears at the same rate H2O appears.
I believe that the answer is Oxygen. Hope this helps. :)
The atmosphere is an important part of what makes Earth livable. It blocks some of the Sun's dangerous rays from reaching Earth. It traps heat, making Earth a comfortable temperature. And the oxygen within our atmosphere is essential for life.
