Infer Xenon, a nonreactive gas used in strobe lights, is a poor conductor of heat and electricity. Would you expect xenon to be a metal, a nonmetal, or a
metalloid? Where would you expect it to be on the periodic table? Explain.

Answers

Mark the lime poor conducter of heat and electricity.

Hence it's non metal

Yes why no ,Xenon is already has its secured place in modern periodic table.

It belongs to group 18,the Helium family and inert gas group having atomic no Z=54

Xenon is a non-reactive gas. It will not conduct and react normally. Thus it can be classified as a non-metal. Xenon is placed in the inert gas or noble gas group that is group 18.

What are noble gases?

Noble gases are inert gases in the 18th group of periodic table. Noble gases have completely filled orbitals and thus they no need other electrons.

Atoms participate in reaction when they are not stable because of the insufficient valence electrons. Noble gases such as argon, krypton, neon, xenon etc. have 8 valence electrons and thus are not reactive.

Metals are highly conductive and they are placed in the left side of periodic table. In periodic table, from left to right the metallic nature decreases and the other elements are called non-metals. Most of the non-metals are gases and very few such as silicon is metalloid.

Non-metals are insulators or poorly conduct electricity. Hence, xenon is a non-metal placed in the 18th group of periodic table.

d. 2mol of co(g) remains unreacted.
e. 144g of co2(g) is produced.

Answers

Based in the equation of the reaction, oxygen gas, O2 is the limiting reactant and 2 moles of CO remain unreacted

What is the equation of reaction between CO and O2?

The reaction of carbon(ii) oxide, CO and oxygen, O2 is a redox reaction which produces carbon (iv) oxide, CO2.

The equation of the reaction. is given below:

2 CO + O2 ----> 2 CO2

From the equation of the reaction, 2 moles of CO are required to react with 1 mole of O2 to produce 2 moles of CO2

The moles of the reacting substances is calculated using the formula:

moles = mass/molar mass

Molar mass of CO = 28 g

Moles of CO = 112/28 = 4 moles

Molar mass of 02 = 32 g

Moles of O2 = 32/32 = 1 mole

Therefore, oxygen gas, O2 is the limiting reactant and 2 moles of CO remain unreacted.

Of the following acids, determine a. The strongest acid b. The acid that produces the lowest concentration of hydronium ions per mole of acid

Answers

Answer:

The bond strength of an acid generally depends on the size of the 'A' atom: the smaller the 'A' atom, the stronger the H-A bond. When going down a row in the Periodic Table (see figure below), the atoms get larger so the strength of the bonds get weaker, which means the acids get stronger.

Explanation:

The acid that is strongest of the following is HNO₃ and the acid that produces the lowest concentration of hydronium ions per mole of acid is HF.

What are weak and strong acids?

Strong acids are completely dissociated into a solution.

Examples of strong acids are Hydrochloric acid, sulfuric acid, nitric acid, etc.

Weak acids are those that do not completely dissociate in a solution.

Examples are formic acid, acetic acid, nitrous acid, etc.

Thus, the acid that is strongest of the following is HNO₃ and the acid that produces the lowest concentration of hydronium ions per mole of acid is HF.

Explanation:

Molarity = number of moles / volume

If 550 mL of a 3.50 M KCl solution are set aside and allowed to evaporate until the volume of the solution is 275 mL, which is half of 550 mL, the molarity of the solution with the same number of moles of KCl is 3.5 * 2 = 7.00 M

The molarity of the solution will be 7 M.

What is  molarity ?

The total count of moles of solute per liter of a particular solution is known as a solution's molarity.

What is solution?

The volume of just an object is a measurement of how much space it takes up.

Molarity of the solution can be determined by the formula:

[tex]M_{1} V_{1} = M_{2} V_{2}[/tex]

where, M = molarity of solution. V = volume.

Given data:

[tex]M_{1}[/tex] = 3.50 M

[tex]M_{2}[/tex] = ?

[tex]V_{1}[/tex] = 550 mL

[tex]V_{2}[/tex] = 275 mL

Now, put the value of given data in molarity equation.

[tex]V_{2} = M_{1} V_{1} /M_{2}\\V_{2} = (3.50 M) (550 mL) / (275 mL)\\V_{2} = 7 M[/tex]

Therefore, the molarity of the solution will be 7 M.
