Assume that 3.00 grams of HgO was used in this reaction. To determine the number of moles of oxygen gas formed, you need to know the number of moles of HgO reactant was used. What quantity in moles of HgO were used

Answers

Answer 1

Taking into account the reaction stoichiometry and the definition of molar mass, the quantity of HgO used is 0.01385 moles and 0.006925 moles of O₂ are formed when 3.00 grams of HgO was used.

In first place, the balanced reaction is:

2 HgO → 2 Hg + O₂

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

HgO: 2 molesHg: 2 molesO₂: 1 mole

The molar mass of the compounds is:

HgO: 216.59 g/moleHg: 200.59 g/moleO₂: 32 g/mole

You know that 3.00 grams of HgO was used. Then, the quantity in moles of HgO used, can be calculated using the molar mass of HgO as follow:

[tex]3 gramsx\frac{1 mole}{216.59 grams}[/tex]=  0.01385 moles

Finally, the quantity of HgO used is 0.01385 moles.

To determine the number of moles of oxygen gas formed, the following rule of three can be applied: if by reaction stoichiometry 2 moles of HgO form 1 mole of O₂, 0.01385 moles of HgO form how many moles of O₂?

[tex]amount of moles of O_{2} =\frac{0.01385 moles of HgOx1 mole of O_{2} }{2 moles of HgO}[/tex]

amount of moles of O₂= 0.006925 moles

Then, 0.006925 moles of O₂ are formed when 3.00 grams of HgO was used.

what is the main use of charcol​

Answers

Answer:

Charcoal is produced by the incomplete combustion of plant or animal products. The major use of charcoal is for outdoor cooking. The second largest use of charcoal is in industrial applications in the form of activated charcoal. The activation process involves heating the charcoal subjecting it to steam or treating with a chemical to both remove substances that have adhered to it as well as break it down into finer particles and thus increase the surface area. Activated carbon has been used for its adsorptive properties as a ‘universal antidote’ in cases of poisonings, as a filter aid agent, and in decolorization processes.

The structure of the product that is formed is (2R,3S)-hexane-2,3-diol

The missing compound from the given question known as Hex-2-ene is shown with its stick formula in the reactant side of the image attached below.

Alkene reacts with a peracetic acid via the process of epoxidation of alkenes to produce an intermediate known as oxiranes. This intermediate is later being treated with aqueous acid to give a chemical compound with two hydroxyl substituents known as the glycol(diol) family.  

Hex-2-ene reacts with peracetic acid CH₃CO₃H.

During the process of the reaction, an oxygen atom is moved from the peracetic acid to the C = C double bond, generating an oxirane ring.

Here;

Peracetic acid is considered to be an electrophilic oxidizing agent because the transferred oxygen atom has a positive charge.

The intermediate (oxirane) is further reacted with aqueous acid to produce an enantiomer of the diol family.

the proton concentrations of three solutions at 25 °c are given. classify the solutions as acidic, basic, or neutral.

Answers

This problem is giving information about the proton concentrations of three solutions at 25 °C. Despite they are not numerically given, we can propose three scenarios to see how to approach the question.

Let the following solutions to come up:

[H⁺] = 2.63x10⁻³ M

[H⁺] = 1.00x10⁻⁷ M

[H⁺] = 4.511x10⁻⁹ M

The first step, will be the calculation of the pH for each solution via:

pH = -log([H⁺])

So that they turn out to be:

pH = -log(2.63x10⁻³ M) = 2.580

pH = -log(1.00x10⁻⁷ M) = 7.000

pH = -log(4.511x10⁻⁹ M) = 8.3457

In such a way, since acidic solutions have a pH below 7, neutral have a pH equal to 7 and basic have it above 7, we infer the first one is acidic, second one is neutral and third one is basic.

Thus, you can reproduce this methodology with the proton concentrations you are given.

In a star, nuclear fusion occurs in the
A. core
B. radiative zone
C. photosphere
D. corona

Answers

Answer:

A. Core

Explanation:

The collisions which occur between the hydrogen atoms starts to heat the gas in the cloud. Once the temperature reaches 15,000,000 degrees Celsius, nuclear fusion takes place in the center, or core, of the cloud. The tremendous heat given off by the nuclear fusion process causes the gas to glow creating a protostar.

In a star, nuclear fusion which is a type of  nuclear reaction occurs in the core.

What are nuclear reactions?

There are two types of nuclear reactions which are nuclear fusion and nuclear fission .They involve the combination and disintegration of the element's nucleus respectively.

In nuclear fission, the nucleus of the atom is bombarded with electrons of low energy which splits the nucleus in to two parts .Large amount of energy is released in the process.It is used in nuclear power reactors as it produces large amount of energy.

In nuclear fusion,on the other hand, is a reaction which occurs when two or more atoms combine to form a heavy nucleus.Large amount of energy is released in the process which is greater than that of the energy which is released in nuclear fission process.

ROUND FINAL ANSWER TO 2 DECIMAL PLACES AND DO NOT INCLUDE A UNIT 675 mL of a gas at a pressure of 1.5atm is compressed to 345 mL. What is the new pressure of the gas?​

Answers

This problem is providing the initial volume and pressure of a gas as 675 mL and 1.5 atm and then mentions the final volume as 345 mL and asks for the new pressure of the gas.

Thus, we start off this problem by recalling the concept of Boyle's law as an inversely proportional relationship between pressure and volume:

[tex]P_1V_1=P_2V_2[/tex]

In which we solve for the final pressure, [tex]P_2[/tex] as shown below:

How can you improve your ability to see the indicator color change at the endpoint of a titration?.

Answers

Answer: Place a piece of white paper under the analyte flask throughout the titration

Explanation:

The end point of titration can be made easy by the use of indicators. But we have to be keenly observe for each drop from the burette because, the colour change will be sudden for a drop.

What is titration?

Titration is an analytical technique used to determine the unknown concentration using a standard reagent of known concentration. The standard reagent of known concentration is called titrant and the  one to be determined is called analyte.

Usually analyte is taken in a conical flask and titrant in a burette. The end point of titration is the point at which the reaction is completed in perfect stoichiometry.

In acid-base titrations, the indicators used having different colors in different pH. Hence, the indicator in the analyte will change in color when the acidity of the medium changes. We have to observe keenly for the color change because it happens for any drop.

The adding of titrant from the burette must be dropwise and thus we can get a time to notice the sudden colour change of indicator.

Two chemicals, Z and X react completely to form a product, Y. If 8.7 grams of x react to produce 19.5 grams of Y, how many grams of Z must have reacted to form this much product?

Answers

Answer:

Z= 10.8

Explanation:

The simple formula Z + X = Y can solve this problem. Since we are given that,

X= 8.7 GramsY= 19.5 Grams

Then we can just substitute the actually values for the letters.

Z + 8.7 = 19.5

From here, we can just do simple math to find the answer.

Z + 8.7 - 8.7 = 19.5 - 8.7

Z = 10.8

So, 10.8 grams of Z reacted to form the product.

Therefore in the reaction, there are ³/₂ more moles of NO than NH₃.
