A switch controls the current in a circuit that has a large inductance. The electric arc at the switch (Fig. CQ32.3) can melt and oxidize the contact surfaces, resulting in high resistivity of the contacts and eventual destruction of the switch. Is a spark more likely to be produced at the switch when the switch is being closed, when it is being opened, or does it not matter

Answers

When the circuit is opened, a spark is much more possible.

What is an inductor?

The primary purpose of an inductor is the storage of energy. This is why an inductor helps to eliminate a spark in a circuit.

In the circuit as described in the question, we know that there is no current when the circuit is closed, the current across the inductor remains constant but rapidly decreases at the opening of the circuit this could lead to a spark.

How many grams of aluminum will
react fully with 1.25 moles Cl₂?

Answers

2Al + 3Cl₂ → 2AlCl₃

mol Al = 2/3 x 1.25 = 0.83

mass Al = 0.83 x 27 g/mol = 22.41 g

According to the stoichiometry 21.66 grams of aluminum will react fully with 1.25 moles Cl₂.

What is stoichiometry?

Stoichiometry is the determination of proportions of elements or compounds in a chemical reaction. The related relations are based on law of conservation of mass and law of combining weights and volumes.

Stoichiometry is used in quantitative analysis for measuring concentrations of substances present in the sample.It is useful in balancing chemical reactions.

According to the chemical reaction between aluminium and chlorine, 2 moles of aluminium reacts with 3 moles of chlorine , thus,1.25 moles of chlorine will react 1.25×2/3=0.83 moles which is mass of aluminium =0.83×26=21.66 g.

Thus, 21.66 grams of aluminum will react fully with 1.25 moles Cl₂.

Answers

Answer:

please mark me as brain list

Explanation:

Any substance that contains only one kind of an atom is known as an element. Because atoms cannot be created or destroyed in a chemical reaction, elements such as phosphorus (P4) or sulfur (S8) cannot be broken down into simpler substances by these reactions

Example: Water decomposes into a mixture of hydrogen and oxygen, on the other hand, cannot be decomposed into simpler substances. They are therefore the elementary, or simplest, chemical substances elements.

Each element is represented by a unique symbol. The notation for each element can be found on a periodic table of elements.

The elements can be divided into three categories that have characteristics properties: metals, nonmetals and semimetals. Most elements are metals, which are found on the left and toward the bottom of the periodic table. A handful of nonmetals are clustered in the upper right corner of the periodic table. The semimetals can be found along the dividing line between the metals and the nonmetals.

Find the magnetic force experienced by a proton moving with the speed of 3 × 105 m/s in the magnetic field B of magnitude 6 × 10-5 T.

The magnetic force experienced by a proton moving with a speed of 3 ×[tex]10^{5}[/tex] m/s in the magnetic field B of magnitude 6 ×[tex]10^{-5}[/tex] T will be 2.88×[tex]10^{-18}[/tex] N.

Magnetic force can be defined as the attraction or repulsion force that arises between electrically charged particles due to the motion of the charged particles.

Given,

Speed = 3×[tex]10^{5}[/tex] m/s

Magnetic Field, B= 6 ×[tex]10^{-5}[/tex] T

Magnetic force is the product of velocity, the charge of a proton, and the magnetic field present there.

The magnetic force can be represented as:

F=qvB

F=1.6×[tex]10^{-19}[/tex]×3×[tex]10^{5}[/tex] ×6 ×[tex]10^{-5}[/tex]

F=2.88×[tex]10^{-18}[/tex] N

Choices:
A. C10H8
B. O2
C. CO2
D. H2O

Answers

Answer:

B

Explanation:

The answer is B, O2

O₂ is the limiting reagent.

What is a limiting reactant?

A limiting reactant is described as the one that will be consumed first in a chemical reaction.

Calculation

C₁₀H₈ + 12O₂ → 10CO₂ + 4H₂O

Given, Mass of O₂ = 23.3 g

           Mass of C₁₀H₈ = 18.3 g

Molar mass of O₂ = 32 g

No. of moles of O₂ = 32/23.3 = 1.4 moles

Molar mass of C₁₀H₈ = 128 g

No. of moles of C₁₀H₈ = 128/18.3 = 6.9 = 7 moles

According to the equation,

1 mole of C₁₀H₈ yields 10 moles of CO₂. So, 7 moles of C₁₀H₈, give 70 moles of CO₂.

12 moles of O₂ yields 10 moles of CO₂. So, 1.4 moles of O₂ give 1.16 moles of CO₂.

We do know, however, that based on our balanced equation, if we were to totally react all 1.4 moles of O2, we could only produce a maximum of 1.16 moles of CO2. Even while there is enough C10H8 to generate more, the amount of O2 we have is a limiting factor because it will be consumed first.

So, our limiting reactant is O₂.

If the both pressure and temperature of the helium gas is doubled, the final volume is 1.00 Liters.

What is the final volume of the helium gas?

Combined gas law put together both Boyle's Law, Charles's Law, and Gay-Lussac's Law. It states that "the ratio of the product of volume and pressure and the absolute temperature of a gas is equal to a constant.

It is expressed as;

P₁V₁/T₁ = P₂V₂/T₂

Given that;

Initial volume V₁ = 1.00LInitial Pressure = PInitial temperature = TFinal pressure = 2PFinal temperature = 2TFinal volume V₂ = ?

P₁V₁/T₁ = P₂V₂/T₂

P₁V₁T₂ = P₂V₂T₁

V₂ = P₁V₁T₂ / P₂T₁

V₂ = ( P × 1.00L × 2T ) / ( 2P × T )

V₂ = ( 2.00L × P × T ) / ( 2 × P × T )

V₂ = ( 1.00L × P × T ) / ( × P × T )
