Answer:
NF3< H2S< H2O< He
Explanation:
The average speed of a gas depends on the relative molecular mass of the gas. Lighter gases have a greater average speed and move faster than heavier gases.
Hence, we need to arrange these gases listed in the question in order of decreasing molecular mass in order to obtain the order of increasing Urms assuming equivalent amounts and all gases are at the same temperature and pressure.
Hence; NF3< H2S< H2O< He
The rank in order of increasing Urms for the gases given, assuming the same amount, temperature, and pressure is as follows: NF₃, H₂S, H₂O, and He.
Urms, or root mean square speed, of a gas, depends on the molar mass of the gas and the temperature. It is determined by the formula Urms = sqrt(3kT/M), where k is Boltzmann's constant, T is temperature, and M is the molar mass. The greater the molar mass, the lower the Urms. Looking at the molar masses of the gases H₂S (34 g/mol), He (4 g/mol), NF₃(71 g/mol), and H₂O (18 g/mol), we can rank them in order of increasing Urms as NF₃ 1st), H₂S (2nd), H₂O (3rd), and He (4th).

Answer:
The coefficient of is 3 in the balanced redox reaction.
Explanation:
Oxidation reaction is defined as the chemical reaction in which an atom loses its electrons. The oxidation number of the atom gets increased during this reaction.
Reduction reaction is defined as the chemical reaction in which an atom gains electrons. The oxidation number of the atom gets reduced during this reaction.
For the given chemical reaction:
The half cell reactions for the above reaction follows:
Oxidation half reaction:
Reduction half reaction:
To balance the oxidation half reaction must be multiplied by 3 and reduction half reaction must be multiplied by 2 thus, the balanced equation is:-
The coefficient of is 3 in the balanced redox reaction.
Answer:
A base pair is a pair of bases that form hydrogen bonds in the double stranded DNA molecule.
- Adenine-thymine: A-T
- Guanine-cytosine: G-C
Replication Process:
- Double strand unwinds.
- New nucleorides line up via base pairing.
- Colvalent bonds link nucleotides together in the new strands.
