The statement that is not true regarding the pH scale would be the final one. As the concentration of hydroxide ions in a corresponding solution increases, the pH would increase, as the solution becomes more basic and not as acidic. The pH values from 0-6 account or characterize a solution to be acidic, while from 8-14 would be basic. Increase in hydroxide will increase the pH from original value.
Answer:
0,61 moles of potassium permanganate equal 3.67 x 10^23
Explanation:
The mole is defined as the amount of compound that contains Avogadro's number of particles (atoms, molecules, ions, electrons, etc.). Avogadro's number has a value of: 6,023 · 10e23 particles.
6,023 · 10e23 particles.---1 mol KMn04
3.67 x 10e23 particles-----x=
x= ( 3.67 x 10xe23 particles1 mol KMn04 )/6,023 · 10e23 particles=0,609 moles
C - Negatively charged electrons orbit a positively charged nucleus
Answer is: the collision theory.
The collision theory states that a certain fraction of the collisions (successful collisions) cause significant chemical change.
The successful collisions must have enough energy (activation energy), on this diagram that energy is represented with arrow up.
Chemical bonds are broken (between blue and red-black molecules) and new bonds are formed (between blue-red and blue-black molecules), as it is represented on diagram.
Answer:
An acid is a substance that when dissolved in water produces hydroxonium ion as the only positive ion in water
Explanation:
HCL +H20=H3O + CL
