What mass of copper is consumed in the reaction with hydrochloric acid if 10.0 g of gas is collected?

Answer:

Mass and Volume

Explanation:

Extensive property are the properties which are dependent on the mass or size of the system

The pKw of water at this temprature would be 4, by using the formula for pKw

Although this dissociation is mild, water can split into its ions. The Kw is the dissociation constant, and the ionic product tends to remain constant.

Kw is the equilibrium constant that is connected to the molarity of water in an aqueous solution, so to speak. The concentration of a solute in a solution is indicated by its molarity or molar concentration, which is a volume that varies on temperature.

As a result, whereas the molarity in aqueous solutions is essentially constant, the pKw varies with temperature. When the temperature rises, the pKw decreases; when the temperature falls, the pKw rises.

The fossil fuels that contain sulfur, such as coal and oil is the main cause of acid rain in the world.

The main cause of acid rain in the world is the burning of fossil fuels that contain sulfur, such as coal and oil. When these fuels are burned, they release sulfur dioxide (SO2) and nitrogen oxides (NOx) into the atmosphere, which can react with water, oxygen, and other chemicals to form sulfuric acid (H2SO4) and nitric acid (HNO3). These acids can then fall to the ground as acid rain, causing environmental damage and health problems. Therefore, reducing the use of these fuels or using technologies to reduce their emissions can help to prevent acid rain.

Wascana Chemicals should use emissions reduction technologies to reduce the amount of sulphur dioxide emitted during paint production.

To comply with the Ministry of Environment's directive, Wascana Chemicals, a paint manufacturer, needs to reduce the amount of sulphur dioxide released during paint production. This can be accomplished through the use of emissions reduction technology, such as scrubbers, catalytic converters, or gasification systems.Scrubbers are devices that use a wet process to remove pollutants from gas streams. The gas stream is forced through a scrubbing solution that traps pollutants, including sulphur dioxide.Catalytic converters, on the other hand, use a chemical process to transform pollutants into less harmful substances. Gasification systems convert solid or liquid materials into a gas, which can be combusted to generate energy.

In conclusion, to comply with the Ministry of Environment's emissions reduction regulations, Wascana Chemicals should consider implementing one or more emissions reduction technologies such as scrubbers, catalytic converters, or gasification systems to reduce the amount of sulphur dioxide emitted during paint production.

Answer:Yes. Adding or losing neutrons will change the atomic mass without forming a different element.

Explanation: Brainly

The isotope symbol that fits each description is as follows: 68 neutrons, 47 electrons is Ag b. mass number = 197, 79 electrons is Au c. atomic number = 86, 136 neutrons is Rn d. atomic number = 76, mass number = 192 is Os.

Isotopes are two or more atom types that share the same atomic number (number of protons in their nuclei), location in the periodic table, and chemical element but have distinct nucleon numbers (mass numbers) as a result of having a different number of neutrons in their nuclei. Although the chemical properties of each isotope of a given element are nearly identical, they differ in their atomic weights and physical characteristics.

The name "isotope" refers to the fact that different isotopes of the same element occupy the same location on the periodic table. The word "isotope" is derived from Greek origins that mean "the same place".

Answer:

hot

Explanation:

As a result, the gas's internal energy has decreased by -4.1 kJ. The negative sign denotes a decrease in the gas' internal energy, which is compatible with the gas's exerting force on its surroundings.

The following equation can be used to determine specific heat, abbreviated Cp: Cp=Qm ΔT When m is the material's mass, Q is the quantity of heat energy delivered to the substance, and T is the temperature change of the substance, we can write C p = Q m T.

According to the first law of thermodynamics, a system's internal energy change (E) equals the heat it receives (Q) minus the work it performs (W).

ΔE = Q - W

In this instance, the petrol performs 9.2 kJ of work and absorbs 5.1 kJ of heat (Q = 5.1 kJ). Inputting these values into the previous equation results in:

ΔE = 5.1 kJ - 9.2 kJ

ΔE = -4.1 kJ

Answer:

Amorphous

Explanation:

Some solids such as glass can be heated and cooled in order to shape them.

These are Amorphous.

Approximately 1.52 g of (s)-1-chloro-4-ethyl-2-methylhexane and 2.12 g of triphenylphosphine would be required to get the required product.

Molar mass of (s)-(4-ethyl-2-methylhexyl)triphenylphosphonium = (4 x molar mass of C) + (1 x molar mass of Cl) + (1 x molar mass of P) + (4 x molar mass of H) + (3 x molar mass of C6H5)

= (4 x 12.01 g/mol) + (1 x 35.45 g/mol) + (1 x 30.97 g/mol) + (4 x 1.01 g/mol) + (3 x 78.11 g/mol)

= 628.02 g/mol

Next, we can use stoichiometry to determine how much (s)-1-chloro-4-ethyl-2-methylhexane and triphenylphosphine are required to produce 4.15 g of (s)-(4-ethyl-2-methylhexyl)triphenylphosphonium. The balanced chemical equation for the reaction is:

(s)-1-chloro-4-ethyl-2-methylhexane + triphenylphosphine → (s)-(4-ethyl-2-methylhexyl)triphenylphosphonium chloride

From the balanced equation, we can see that one mole of (s)-1-chloro-4-ethyl-2-methylhexane reacts with one mole of triphenylphosphine to produce one mole of (s)-(4-ethyl-2-methylhexyl)triphenylphosphonium chloride. Therefore, we need to calculate the number of moles of (s)-(4-ethyl-2-methylhexyl)triphenylphosphonium chloride produced from 4.15 g, and then use stoichiometry to determine the amount of (s)-1-chloro-4-ethyl-2-methylhexane and triphenylphosphine required.

Number of moles of (s)-(4-ethyl-2-methylhexyl)triphenylphosphonium chloride = mass / molar mass

= 4.15 g / 628.02 g/mol

= 0.0066 mol

Since the yield is given as 81%, we need to adjust the amount of (s)-1-chloro-4-ethyl-2-methylhexane and triphenylphosphine accordingly:

Amount of (s)-1-chloro-4-ethyl-2-methylhexane = 0.0066 mol / 0.81

= 0.0081 mol

Amount of triphenylphosphine = 0.0066 mol / 0.81

= 0.0081 mol

Finally, we can convert the moles of each compound to grams using their respective molar masses:

Mass of (s)-1-chloro-4-ethyl-2-methylhexane = 0.0081 mol x 186.71 g/mol

= 1.52 g

Mass of triphenylphosphine = 0.0081 mol x 262.29 g/mol

= 2.12 g

Therefore, approximately 1.52 g of (s)-1-chloro-4-ethyl-2-methylhexane and 2.12 g of triphenylphosphine would be required to produce 4.15 g of (s)-(4-ethyl-2-methylhexyl)triphenylphosphonium assuming an  81% yield of reaction.
