Rank each of the following gases in order of increasing Urms assuming equivalent amounts and all gases are at the same temperature and pressure where 1 is the lowest Urms Gas 1: H2S Gas 2: He Gas 3: NF3 Gas 4: H20

Answers

Answer 1

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

Answer 2

Answer:

Final answer:

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.

Explanation:

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).

When the following redox equation is balanced with smallest whole number coefficients, the coefficient for Sn(OH)3– will be _____. Bi(OH)3(s) + Sn(OH)3–(aq) → Sn(OH)62–(aq) + Bi(s) (basic solution)

Answers

Answer:

The coefficient of $Sn(OH)_3^(-)$ 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.

$X\rightarrow X^(n+)+ne^-$

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.

$X^(n+)+ne^-\rightarrow X$

For the given chemical reaction:

$Bi(OH)_3+Sn(OH)_3^(-)\rightarrow Sn(OH)6^(2-)+Bi$

The half cell reactions for the above reaction follows:

Oxidation half reaction: $Sn(OH)_3^(-)+3OH^-\rightarrow Sn(OH)6^(2-)+2e^-$

Reduction half reaction: $Bi(OH)_3+3e^-\rightarrow Bi+3OH^-$

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:-

$3Sn(OH)_3^(-)+3OH^-+2Bi(OH)_3\rightarrow 3Sn(OH)6^(2-)+2Bi$

The coefficient of $Sn(OH)_3^(-)$ is 3 in the balanced redox reaction.

Lewisite (2-chloroethenyldichloroarsine) was once manufactured as a chemical weapon, acting as a lung irritant and a blistering agent. During World War II, British biochemists developed an antidote which came to be known as British anti-Lewisite (BAL) (2,3-disulfanylpropan-1-ol). Today, BAL is used medically to treat toxic metal poisoning. Complete the reaction between Lewisite and BAL by giving the structure of the organic product and indicating the coefficient for the number of moles of HCl produced in the reaction.
