Draw the organic product of the following reaction between (1s 3s)-1-chloro-3-methylcyclopentane

Answers

Answer 1

Whenever we need to find the purity of a combination of two metals, which is known as an alloy, we use the simple formula where we find the weight of the main compound in the numerator and the weight of the total alloy In the denominator. Multiplying this by hundred gives us the purity of the metal. This is extensively used to calculate the purity of silver and gold.

Safety standards require a pool to add 333 chlorine tablets to every 2{,}0002,0002, comma, 000 liters of water. Today, the lifeguards at Park Pool added 888 chlorine tablets to their pool's 10{,}00010,00010, comma, 000 liters of water. How does Park Pool's chlorine compare to the safety standards

Answers

Compared to safety standards, that would be too little chlorine:

10,000 gallons is five times as much water as 2,000.

Therefore, Park's pool needs five times as much chlorine as is required for 2,000 gallons to meet safety regulations.

5 times 3 pills of chlorine equals 15 tablets. For Mark to meet safety standards, 15 chlorine tablets would be required. Use one three-inch tablet for every 10,000 gallons of pool water rather than stuffing your chlorinator or floater to the brim with tablets. This quantity of pills should be sufficient to maintain a good chlorine level if you shock your water once a week.

CH4 + 2 Cl₂ →→ 4 HCl + C
4. Use the equation above to calculate how many moles of CH4 are required to
produce 3.6 moles of HCl. (2 pts)

Answers

By using given equation 0.9 moles of CH₄ are required to produce 3.6 moles of HCl.

In simple terms, what is a chemical reaction?

The transformation of one or more reactants, also known as reactants, into one or more new products, also known as products, occurs during a chemical reaction.

Chemical reactions turn reactants into products by involving reactants in the process. As an illustration, when we breathe, oxygen is inhaled, and upon coming into contact with glucose, it reacts to create carbon dioxide, water, and energy.

Given chemical reaction:

CH₄ + 2 Cl₂ → 4 HCl + C

1 mole of CH₄ gives 4 moles of HCl

x moles of CH₄ gives 3.6 moles

x moles of CH₄ = 3.6/4

x moles of CH₄ = 0.9moles.

How does the volume change if 50mL of a gas material is cooled from 30\deg C to 5\deg C ?
50mL
46mL
100mL
56mL

Answers

The final volume can be determined using Charles's law. The volume of gas at 5 degree Celsius will be 8.3 ml.

What is Charles's law of gases ?

According to Charles's law, at constant pressure, the volume of a gas is directly proportional to the temperature.

Hence, V/T = constant.

Let, V1 and T1 be the initial volume and temperature and V2, T2 be the final quantities.

then, V1/T1 = V2/T2.

V2 = V1 T2/ T1

Given, V1 = 50 ml

T1 = 30 °C

T2 = 5 °C

Then, V2 = 50 ml × 5 °C /30 °C = 8.3 ml

Therefore, the volume of the gas reduces to 8.3 ml.

2H(g) + [tex]O_{2}[/tex] ⇒ 2H2O This equation obeys the law of conservation of mass.

The law of conservation of mass states that mass is neither created nor destroyed in chemical reactions. For example, carbon atoms in coal become carbon dioxide when burned. A carbon atom changes from a solid structure to a gas, but its mass remains the same.

In a chemical reaction, the mass of the chemical components before the reaction equals the mass of the components after the reaction. Therefore, for chemical reactions and low-energy thermodynamic processes in isolated systems, the total mass of reactants or starting materials must equal the mass of the products.

Look at the general chemical equation below. A B C Which situation best describes the effect of a limiting reactant

Answers

The situation that best describes the effect of a limiting reactant is that when there is not enough A reactant to react with whole B.

The limiting reactant, also known as the limiting reagent, is the reactant that is used first during a chemical reaction, hence restricting the amount of product that can be produced. The limiting reactant can be identified in a variety of methods ,but they all require employing mole ratios from the balanced chemical equation.

The theoretical yield is the maximum quantity of product possible given the limiting reactant. The quantity of product actually procured, or actual yield, is usually always less than the theoretical yield. The percentage yield used to describe the actual yield indicates what portion of the theoretical yield was attained.

In the equation there is only one situation which describes the effect of limiting reagent when there is not enough of A to react with whole B.

How many moles are in 1gm?

The mole is the fundamental unit of substance quantity in the SI. 0.041143797572516 moles make up 1 gram of magnesium. The grams to moles formula Use the grams to moles formula to calculate the number of moles, n, of a substance with a given mass, m, (in grams) accurately. n = m / M.

Depending on the substance, yes. As a reminder, a mole is equal to 6.02 1023 atoms and is used to measure quantities. Therefore, it stands to reason that lead and hydrogen would weigh differently. Less moles would be required because it would take a lot fewer lead atoms to make up 1 gram. However, one hydrogen atom has far less mass than one lead atom, therefore more atoms (and moles) would be required to create one gram.

Write the chemical symbols for three different atoms or atomic anions with 10 electrons

Answers

Answer:

          i)  Neon (Ne)

           ii)  Fluoride Ion (F⁻¹)

            iii)  Oxide Ion  (O⁻²)

Explanation:

                  Ions are those charged species which are either positively charged (by loosing electrons) called as cations or negatively charged (by gaining electrons) called as anions.

                 In given examples, Neon is a neutral atom which has an atomic number 10. It contains 10 electrons in its neutral state with the electronic configuration 1s², 2s², 2p⁶.

                 Fluorine atom has an atomic number of 9. Therefore, it contains 9 electrons in its neutral state with an electronic configuration of 1s², 2s², 2p⁵. When Fluorine atom gains one electron it gets 10 electrons with electronic configuration of 1s², 2s², 2p⁶.

                Oxygen atom has an atomic number of 8. Therefore, it contains 8 electrons in its neutral state with an electronic configuration of 1s², 2s², 2p⁴. When Oxygen atom gains two electron it gets 10 electrons with electronic configuration of 1s², 2s², 2p⁶ forming an Oxide Ion.

You have 56.8 mL of a gas collected at 664 mmHg and 135 K. What volume will it occupy at 632 mmHg and 196 K? *

Answers

Answer:

86.6 mL

Explanation:

From the question given above, the following data were obtained:

Initial volume (V₁) = 56.8 mL

Initial pressure (P₁) = 664 mmHg

Initial temperature (T₁) = 135 K

Final pressure (P₂) = 632 mmHg

Final temperature (T₂) = 196 K

Final volume (V₂) =?

The final volume of the gas can be obtained as follow:

P₁V₁/T₁ = P₂V₂/T₂

664 × 56.8 / 135 = 632 × V₂ / 196

Cross multiply

135 × 632 × V₂ = 664 × 56.8 × 196

85320 × V₂ = 7392179.2

Divide both side by 85320

V₂ = 7392179.2 / 85320

V₂ = 86.6 mL

Therefore, the final volume of the gas is 86.6 mL
