How many moles of nitrogen dioxide, NO2, are present if the reaction conditions are 330 K, 2.46 atm, and 4.8 L

Answers

Answer 1

There are 0.436 moles of nitrogen dioxide, NO2, present if the reaction conditions are 330 K, 2.46 atm, and 4.8 L.

IDEAL GAS LAW:

The number of moles of nitrogen dioxide (NO2) in this question can be calculated by using the ideal gas law equation as follows:

PV = nRT

Where;

P = pressure (atm)V = volume (L)T = temperature (K)R = gas law constant (0.0821 Latm/molK)n = number of moles

According to the reaction conditions given in this question;

P = 2.46 atmV = 4.8Ln = ?T = 330K

2.46 × 4.8 = n × 0.0821 × 330

11.81 = 27.093n

n = 11.81 ÷ 27.093

n = 0.436mol

Therefore, there are 0.436 moles of nitrogen dioxide, NO2, present if the reaction conditions are 330 K, 2.46 atm, and 4.8 L.

To name the binary ionic compounds it is necessary to observe which is the metal and the non-metal that compose them.

This name is made as follows:

The name of the metal is shown.The name of the non-metal is presented in abbreviated form.Add the suffix "ide" at the end.

An example of this can be seen in the binary ionic composite KCL that receives the name Potassium Chloride, since potassium is the metal and chlorine is the non-metal.

It is important to remember that binary ion compounds are electrically charged ionic molecules formed by a metal and not a non-metal.

A 0.03 mol sample of NH4NO3 (s) is placed in a 1 L evacuated flask, which is then sealed and heated. The NH4NO3 (s) decomposes completely according to the balanced equation above. The total pressure in the flask measured at 400 K is closest to which of the following? (The value of the gas constant, R, is 0.082 L atm mol-1 K-1.)
a. 3 atm
b. 1 atm
c. 0.5 atm
d. 0.1 atm
e. 0.03 atm

Answers

The total pressure in the flask measured at 400 K is 1 atm

The correct answer to the question is Option B. 1 atm

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

Number of mole (n) = 0.03 mole Volume (V) = 1 L Temperature (T) = 400 KGas constant (R) = 0.082 atm.L/Kmol Pressure (P) =?

Using the ideal gas equation, we can obtain the pressure in the flask as follow:

PV = nRT

P × 1 = 0.03 × 0.082 × 400

P = 1 atm

Therefore, the total pressure in the flask measured at 400 K is 1 atm

The bond angle obtained based on the geometry of the molecule alone is known as the predicted bond angle.

When a compound is formed, the less electronegative atom in the compound is called the central atom in the molecule. The angle formed by the nuclei of two surrounding atoms with the nucleus of the central atom in a structure is called a bond angle.

The bond angle is usually based on the geometry of the molecule. The expected geometry can be deviated for certain reasons such as the presence of lone pairs on the central atom in the molecule.

Part 1: Name the type of chemical reaction that occurs when magnesium chloride
solution (MgCl2) reacts with sodium carbonate solution (Na2CO3).
Part 2: Explain why aluminum (AI) would react with copper chloride (CuCl2) but not with
magnesium chloride (MgCl2).

Answers

Mg is ahead of Al in the electrochemical series and more reactive than Al hence Al does not react with MgCl2.

A chemical reaction is said to have occurred when new substances are formed. The reaction between magnesium chloride  solution and sodium carbonate solution is a double decomposition reaction since the cations exchange anion partners in the product;

MgCl2(aq) + Na2CO3(aq) ------> MgCO3(s) + 2NaCl(aq)

We must note that a single replacement reaction depends on the relative positions of metals in the electrochemical series. Al can react with CuCl2 because Al is more reactive than copper and ahead of Cu in the electrochemical series. On the other hand, Mg is ahead of Al in the electrochemical series and more reactive than Al hence Al does not react with MgCl2.

1) How many moles of hydrogen gas can be produced if 0.57 moles of hydrochloric
acid, HCl, reacts with excess solid zinc according to the following chemical
equation?
2 HCl + Zn → Hz + ZnCl2

Answers

Answer: 0.28 mol H2

Explanation:

0.57mol HCl         1mol H2          

                             2mol Hcl

Hydrochloric acid and zinc show the displacement reaction to produce hydrogen gas and zinc chloride. 0.57 moles of hydrochloric acid and excess zinc react to produce 0.28 mol H₂.

What is a displacement reaction?

A displacement reaction is the removal of one of the elements from the reactant with highly active species of the reactivity species to produce the products. It can be a single or double displacement reaction.

The balanced chemical displacement reaction is given as:

2 HCl + Zn → H₂ + ZnCl₂

Here, two hydrochloric acids react with zinc to form one mole of hydrogen gas and one mole of zinc chloride.

Given,

Hydrochloric acid = 0.57 moles

Using proportions to calculate moles as:

If 2 moles of HCl = 1 mole H₂

Then, 0.57 moles = X moles

X = 0.57 ÷ 2

= 0.28 mol H₂

Therefore, 0.57 mole HCl produces 0.28 moles of hydrogen gas.
