Explanation:
These are called quantum numbers: there are 4, but the first three are mainly used, only in orbital notation will you use all four.
The first is the electron's energy level or "shell", used as n. (Principle QN)
The second relates to the shape of the orbital and is used as l, when n and l are put together it defines the sublevel or subshell. (Angular Momentum QN)
The third one relates to the orientation of the electrons in that sublevel used as m(sub)l. (Magnetic QN)
The fourth one relates to the spin states of the electron, since they spin opposite directions, used as m(sub)s. (Electron Spin QN)
Answer: oxygen
Explanation: as you go across period on the periodic table, the elements get larger. Their atomic masses also increase meaning it gets heavier and thus larger.
Answer:
H2 (g) + I2 (g) = 2HI (g)
Explanation:
Forward reaction:H2(g)+I2(g)→2HI(g)
Reverse reaction:2HI(g)→H2(g)+I2(g)
<span>The answer is the first option. Enzyme and substrate bind using a lock-and-key mechanism. Enzymes act on a specific substrate and a substrate needs a specific enzyme, this is what is called a lock-and-key mechanism. Enzymes and substtates are like a key and a lock, one is for each other.</span>
