Nitrogen — 78 percent.
Oxygen — 21 percent.
Argon — 0.93 percent.
Carbon dioxide — 0.04 percent.
Trace amounts of neon, helium, methane, krypton and hydrogen, as well as water vapor.
The answer would be
35 ============= > A CL = ============> CL 17 === = ======== >Z
37 CL 17 Isotopes mean A different and equal Z.
Isotopes are atoms that have the same number of protons but a different number of neutrons but still belong to the same element. Though they have the same atomic number but not the same mass number.
Answer:
Explanation:
1. Write the equation for the half-reaction.
Mg²⁺ + 2e⁻ ⟶ Mg
The number of electrons transferred (z) is 2 mol per mole of Mg.
2. Calculate the number of coulombs
Q = It
3. Mass of Mg
We can summarize Faraday's laws as
Answer:
1. SOCl2/pyridine
2. NH3
3. LiAlH4
4. H2O
Explanation:
In the conversion of (S)-3-methyl-3-phenylpentanoic acid to (5)-3-methyl-3-phenylpentanamine, SOCl2/pyridine is first added to the (S)-3-methyl-3-phenylpentanoic acid
This is then followed by the addition of NH3 is subsequently added followed by reduction using LiAlH4 which reduces the carbonyl carbon to an alkane. addition of water completes the mechanism and leads to the formation of the product.
Answer:
A saturated solution can become supersaturated when it is cooled. The solubility of solid solutes in liquid solvents increases as the solvent is warmed up. For example, you can dissolve more sugar in warm water as opposed to cold water.
