How many grams of KCiO3 are needed to make 186.2mol of KCi

Answers

Answer 1

Answer:

64.2 L

Explanation:

In order to be able to calculate the volume of oxygen gas produced by this reaction, you need to know the conditions for pressure and temperature.

Since no mention of those conditions was made, I'll assume that the reaction takes place at STP, Standard Temperature, and Pressure.

Under these conditions for pressure and temperature, one mole of any ideal gas occupies 22.7 L

- this is known as the molar volume of a gas at STP.

So, in order to find the volume of oxygen gas at STP, you need to know how many moles of oxygen are produced by this reaction.

The balanced chemical equation for this decomposition reaction looks like this:

2KClO3(s] −−−→2KCl(s]+3O2(g]↑

Notice that you have a 2/3 mole ratio between potassium chlorate and oxygen gas. This tells you that the reaction will always produce 3/2 times more moles of oxygen gas than the number of moles of potassium chlorate that underwent decomposition.

Use potassium chlorate's molar mass to determine how many moles you have in that 231-g sample.

231g ⋅ 1 mole KClO3/ 122.55g = 1.885 moles KClO3

Use the aforementioned mole ratio to determine how many moles of oxygen would be produced from this many moles of potassium chlorate

1.885 moles KClO3 ⋅ 3 moles O2/2 moles KClO3 = 2.8275 moles O2

So, what volume would this many moles occupy at STP?

2.8275 moles ⋅ 22.7 L/ 1mol = 64.2 L

in a 52 weeks high and low, if the numbers show difference between each other, there is less risk of loss - but there is also less opportunity for gain, either.

Answers

Smaller numbers mean less risk of losing, but  less chance of gain, Volatility.

What is gain?In electronics, gain is a measure of the ability of a two-terminal circuit (often an amplifier) ​​to increase the power or amplitude of a signal from its input. Adjusting the gain control sets the amount of distortion in the sound no matter how loud the final volume is set. This means  that the gain setting determines how clean or dirty the sound is, regardless of the master volume setting.Gain is simply the amplification factor, i.e. the parts of the output power to input power. Wins are often expressed in percentages, especially for small wins. Example 3% of ratio signifies to a power gain of 1.03.

Charles' law is a law that studies the behavior of gases in chemistry, such as how temperature affects the volume of a gas under constant pressure. Charles's law describes empirical relationships in the form of special cases of the general gas law and can be derived from the kinetic theory of gases assuming an ideal gas.

According to Charles' law, if a gas is contained in a closed chamber with constant mass and constant pressure, then its volume is directly proportional to its absolute temperature. So when the volume of a gas is directly proportional to the constant temperature, when the temperature of the gas increases, the volume will also increase.

g dan koshland suggested the induced-fit mechanism for enzymes. which of the following cartoons illustrates the induced-fit hypothesis of enzyme-substrate interaction?

Answers

The induced-fit hypothesis of enzyme-substrate interaction illustrates that there is a conformational change in the active site of the enzyme when a substrate binds to it.

According to the induced-fit model, a substrate attaches to an active site, and the two of them slightly alter their shapes to form the perfect fit for catalysis. By bringing substrates together in the best possible orientation, enzymes encourage chemical reactions by establishing the perfect chemistry for the reaction to take place. According to the induced fit hypothesis, an enzyme's active site is not architecturally ideal for substrate binding while it is in the unbound state, or when it is not binding to a substrate. Refer to the image attached for the cartoon illustration.

This induced fit theory extends the lock-and-key idea proposed 100 years ago. In addition to explaining regulatory and cooperative effects, the new theory put out by D. E. Koshland, Jr. in 1958 also provides some new specificity notions. This theory states that an enzyme's unbound active region is not structurally suitable for substrate binding (i.e., not bound to the substrate).

nacl solutions of equal volume and concentration were kept in flasks and held at different temperatures. the two solutions were combined in a larger flask. based on this information, which of the following predictions is correct?

Answers

When equal volume and concentration of NaCl solutions, held at different temperatures, are combined in a larger flask, the final solution will have the following characteristics:

The final concentration of NaCl will be the same as the initial concentrations of the two solutions that were combined. This is because the volume and concentration of the solutions were equal, and therefore the number of moles of NaCl in each solution was also equal. When equal moles of a substance are combined, the concentration of that substance in the final solution will be the same as the initial concentrations.

The final temperature of the solution will be a function of the initial temperatures of the two solutions and the heat capacities of the solutions. The heat capacity of a solution is the amount of heat required to raise the temperature of a given amount of the solution by one degree. If the heat capacities of the solutions are equal, then the final temperature will be the average of the initial temperatures. If the heat capacities are not equal, then the final temperature will be closer to the solution with the larger heat capacity.

If the initial temperatures of the two solutions are very different, the mixing process may cause heat loss or gain to the surroundings, depending on whether the initial temperature of the solution is higher or lower than the surrounding temperature.

In summary, the combination of equal volume and concentration of NaCl solutions, held at different temperatures, in a larger flask will result in a solution with the same NaCl concentration but a temperature that is determined by the initial temperature and heat capacities of the solutions.

Answers

True: Chemists knew that something other than mass influences the properties of elements.

The periodic table organizes elements according to periodic properties, which are recurring trends in physical and chemical properties. First, electrons are added one at a time across a period, from left to right. As this occurs, the electrons in the outermost shell experience increasing nuclear attraction, bringing them closer to the nucleus and more tightly bound to it. Second, moving down a column in the periodic table loosens the outermost electrons' bond to the nucleus. Thus, number of valence electrons, or valency, other than mass influences the properties of elements.

This occurs because the number of filled principal energy levels (which protect the outermost electrons from nucleus attraction) decreases within each group. The periodicity observed in the elemental properties of atomic radius, ionization energy, electron affinity, and electronegativity are explained by these trends.

N₂: 1 moleH₂: 3 molesNH₃: 2 moles

The molar mass of the compounds is:

N₂: 28 g/moleH₂: 2 g/moleNH₃: 17 g/mole

By reaction stoichiometry, the following mass quantities of each compound participate in the reaction:

N₂: 1 mole ×28 g/mole= 28 gramsH₂: 3 moles ×2 g/mole= 6 gramsNH₃: 2 moles ×17 g/mole= 34 grams

Mass of O₂ required

The following rule of three can be applied: If by reaction stoichiometry 34 grams of NH₃ are produced by 6 grams of H₂, 84.2 grams of NH₃ are produced by how much mass of H₂?

mass of H₂= (84.2 grams of NH₃× 6 grams of H₂)÷ 34 grams of NH₃

mass of H₂= 14.86 grams

Finally, 14.86 grams of H₂ are needed.
