Answer:
o increase the rate of chemical reaction
Explanation:
Enzymes are chemical catalysts that speed up chemical reactions by lowering their activation energy. Enzymes have an active site with a unique chemical environment that fits particular chemical reactants for that enzyme, called substrates. Enzymes and substrates are thought to bind according to an induced-fit model.
Protons and neutrons have about the same mass. Electrons are the smallest out of the three, in fact, protons weigh 1,836 times more than an electron.
Answer:
because it showed how the electron could orbit the nucleus without falling into it.
The answer is rubidium -91 because it takes a shorter time of 58.4 seconds to become stable.
NH3 + H20 YIELDS NH4+ + OH-
So, the NH3 and the OH- are stoichiometrically equivalent.
So, we have 0.15M OH-
p OH = -log [OH-]
p OH = -log[0.15) = 0.824
pH = 14 - p OH
pH = 13.18
