Hello!
Reaction rate, the speed at which a chemical reaction proceeds.
Oh yes another person answered the same thing before me. Sorry if I was inconvenient.
Hope you pass or understand everything, though! Good luck!

The BrO2- ion has one more oxygen (a very electronegative element) than does BrO-, hence BrO2- is more electronegative. This weakens the H-O bond which makes it easier for the H to come off as H+ (i.e. act as an acid). HBrO2 is shown below.
<span>O=Br-O-H </span>
<span>By the same argument, HBrO4 is a stronger acid than HBrO3 which is a stronger acid than HBrO2.</span>
Answer:
An orbital is a region in space where there is a high probability of finding an electron.
Explanation:
The orbital is a concept that developed in quantum mechanics. Recall that Neils Bohr postulated that the electron occupied stationary states which he called energy levels. Electrons emit radiation when the move from a higher to a lower energy level. Similarly, energy is absorbed by an electron to move from a lower to a higher orbit.
This idea was upturned by the Heisenberg uncertainty principle. This principle state that the momentum and position of a particle can not be simultaneously measured with precision.
Instead of defining a 'fixed position' for the electron, we define a region in space where there is a possibility of finding an electron with a certain amount of energy. This orbital is identified by a set of quantum numbers.
Answer:
This is false.
Explanation:
This statement directly opposes the first law of thermodynamics which states that energy can neither be created nor destroyed, but can transfer from one source to another.
