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.

Explanation:

A simple test that will distinguish flour from sugar is to dissolve the unknown substance in water.

Sugar dissolves in water due to the presence of polar groups in the chemical structure of sugar that are capable of interaction with water.

Flour does not dissolve in water. It rather becomes suspended in water when agitated and settles at the bottom of the container when the suspension is left to stand.

Solid is the state in which matter maintains a fixed volume and shape; liquid is the state in which matter adapts to the shape of its container but varies only slightly in volume; and gas is the state in which matter expands to occupy the volume and shape of its container.??.....

Answer:

228.7\(dm^{3}\)

Explanation:

According to Boyle's law

P1V1 = P2V2

where P1& P2 are initial and final pressure

and V1& V2 and initial and final volumes respectively.

Given:

P1 = 136atm, P2 = 131.6atm

V1 = 142\(dm^{3}\); V2 = ?

V2 = \(\frac{P1V1}{P2}\) = \(\frac{136*142}{131.6}\)

= 146.7\(dm^{3}\)

Total volume, V = V1 + V2

=146.7 + 142

= 228.7\(dm^{3}\)

Answer:

\(\boxed {\boxed {\sf 81.4 \ g\ KOH}}\)

Explanation:

We are asked to convert 1.45 moles of potassium hydroxide (KOH)  to grams.

The molar mass is the mass in grams of 1 mole of a substance. The values are found on the Periodic Table. They are the same as the atomic masses but the units are grams per mole (g/mol) instead of atomic mass units (amu).

We have the compound KOH. Look up the molar masses of the individual elements.

The formula for the compound has no subscripts, so there is 1 mole of each element in 1 mole of the compound. We can simply add the molar masses.

Based on the molar mass, there are 56.105 grams of KOH in 1 mole. Create a ratio using this information.

\(\frac {56.105 \ g\ KOH}{ 1 \ mol \ KOH}\)

We are converting 1.45 moles of KOH to grams, so we multiply by this value.

\(1.45 \ mol \ KOH *\frac {56.105 \ g\ KOH}{ 1 \ mol \ KOH}\)

The units of moles of KOH cancel.

\(1.45\ *\frac {56.105 \ g\ KOH}{ 1 }\)

\(81.35225 \ g\ KOH\)

The original measurement of moles has 3 significant figures, so our answer must have the same.

For the number we calculated, that is the tenths place. The 5 in the hundredths place (81.35225) tells us to round the 3 up to a 4.

\(81.4 \ g\ KOH\)

Approximately 81.4 grams of potassium hydroxide are represented by 1.45 moles.

Answer:

an element with a large number of valence electrons and a large atomic radius

Explanation:

Electronegativity means a tedency when an atom attracts bonding electrons in a covalent bond situation.

» If an atom has many valency electrons [ empty orbitals in outermost shell ], it has difficulty in attracting electrons hence electronegativity low.

» If an atom is large, its nuclear attraction force of incoming electrons is low hence low electronegativity.

\(.\)

The element that would have the lowest electronegativity is an element with a small number of valence electrons and a large atomic radius.

Both electronegativity and atomic radius are periodic trends. Electronegativity increases across the period while atomic radius decreases across a period.

An element that has a small number of valence electrons and a large atomic radius will most likely be a metal hence it will have the lowest electronegativity.

The reproductive system contains the ovaries (female) and testes (male).

The endocrine system contains the pituitary, adrenal, and thyroid glands.

The circulatory system contains three independent systems that work together, the heart (cardiovascular), the lungs (pulmonary), and arteries, veins, coronary and portal vessels (systemic).

The respiratory/pulmonary system contains the nose, mouth, throat (pharynx), voice box (larynx), windpipe (trachea) , airways (bronchi) , and lungs.

Explanation 3:

Mitosis is the process in cell division where the nucleus divides into two nuclei, each with an identical set of chromosomes.

Interphase: occurs when the cell begins to replicate the nuclear DNA material

Stage 1 - Prophase: chromosomes begin to undergo a condensation process that will continue until metaphase. The spindle also begins to form as the two pairs of centrioles move to opposite poles.

Stage 2 - Prometaphase:  Chromosomes are pulled in opposite directions by microtubules growing out from both poles of the spindle until balanced.

Stage 3 - Metaphase:  The centromeres of all the cell's chromosomes line up at the equator of the spindle.

Stage 4 - Anaphase: The chromosomes move away from one another to opposite poles of the spindle.

Stage 5 - Telophase and Cytokinesis: The chromosomes reach the poles, the nuclear membrane then reforms, and the chromosomes begin to decondense. This is followed by cytokinesis, or the division of the cytoplasm into two daughter cells.

Most of my sources say that the nuclear membrane occurs during prophase, but the stages are listed in this order. Regardless, your answer would be A. The nuclear membrane disappears.

Question 5: When magnesium chloride (MgCl2) is dissolved in water, which statement must be true?

Answer: The sum of the mass of the Mg2+ ions and the mass of the Cl– ions must be equal to the mass of MgCl2.

The better Lewis structure for the formula COCl2 is the one where the carbon atom is double-bonded to one oxygen atom and single-bonded to two chlorine atoms. This is because it satisfies the octet rule for all atoms involved and has no formal charges.

The Lewis structure for COCl2 is as follows:

      Cl      Cl
      |       |
      C = O
     
In this structure, the carbon atom has four bonds (one double bond with oxygen and two single bonds with chlorine), satisfying the octet rule. The oxygen atom also has two lone pairs of electrons, giving it a total of eight valence electrons and satisfying the octet rule. The two chlorine atoms each have three lone pairs of electrons and one single bond with carbon, also satisfying the octet rule.

There are no formal charges in this structure, as all atoms have the same number of valence electrons as their respective group numbers in the periodic table (4 for carbon, 6 for oxygen, and 7 for chlorine).

Therefore, this is the better Lewis structure for COCl2, also known as phosgene.

The window on the left side of the simulation shows the reaction a bc ⇌ ab c. This reaction is different from the reaction by which ammonia is synthesized in several ways. The reaction by which ammonia is synthesized is an exothermic reaction, whereas the reaction shown in the simulation is an endothermic reaction.

In an exothermic reaction, heat is produced as the reaction progresses, while in an endothermic reaction, heat is absorbed from the surroundings.

The synthesis of ammonia is an exothermic reaction that occurs as follows:

N2(g) + 3H2(g) ⇌ 2NH3(g) + Heat

The reaction produces heat as it progresses.

It is a reversible reaction, and it occurs at high temperature and pressure.

In contrast, the reaction shown in the simulation is endothermic.

This means that the reaction requires heat to proceed.

The reaction is reversible and can be written as follows:

a bc ⇌ ab + c

The reaction requires energy in the form of heat to proceed from left to right.

When energy is supplied to the system, the reaction proceeds from left to right, and when energy is removed from the system, the reaction proceeds from right to left.

In conclusion, the reaction shown in the simulation is different from the reaction by which ammonia is synthesized in several ways, including their exothermic and endothermic nature.

Red gold is a gold-copper alloy that is commonly used to make jewelry. To calculate the percentage by mass of each metal in the jewelry, you need to determine the mass of gold and copper in the jewelry. The mass of gold can be calculated using the density of gold and the volume of gold in the jewelry:

mass of gold = density of gold * volume of gold

mass of gold = 19.3 g/cm³ * 0.559 cm³

mass of gold = 10.8 g

The mass of copper can be calculated using the density of copper and the volume of copper in the jewelry:

mass of copper = density of copper * volume of copper

mass of copper = 8.96 g/cm³ * (0.559 cm³ - 0.559 cm³)

mass of copper = 0 g

The total mass of the jewelry is 10.8 g + 0 g = 10.8 g.

Therefore, the percentage by mass of gold in the jewelry is 10.8 g/10.8 g = 100%. The percentage by mass of copper in the jewelry is 0 g/10.8 g = 0%.

Answer: 8. 75 kilometers

Explanation:  5.44x 1.609344= 8.7548 Kilometers

We are given with mass of Nitrogen and oxygen as

Percentage of Nitrogen is= 36.84%

Percentage of Oxygen is = 63.16%

Which means for a 100g of sample, mass of Nitrogen will be 36.84g and mass of Oxygen will be 63.16 g

We know that

Number of moles= given mass/molar mass

So,

Number of moles of Nitrogen= Given mass/molar mass

= 36.84/14 = 2.6 moles

Similarly,

Number of moles of oxygen= Given mass/molar mass

= 63.16/16 = 3.9 moles

So we can say that,

In the given compound

Ratio of no of moles of Nitrogen to the no of moles of Oxygen is = 2.6 : 3:9 =2:3
