Aluminum chloride and cesium undergo a single replacement reaction. What is the correct chemical equation for this reaction?a. AlCl3 + 3Cs yields No Reaction
b. AlCl2 + 2Cs yields 2CsCl + Al
c. AlCl3 + 3Cs yields 3CsCl + Al
d. 2AlCl3 + 6Cs yields 2AlCs3 + 3Cl2

Answers

Answer 1

Answer:

Answer is C.

Explanation;

Single replacementreaction is a chemical reaction between an element and a compound. Theelement takes the position of another element in the compound by replacing.

Common equation is

A + BC → AC + B

Al is in 13th group ofthe periodic table. Hence, Al forms Al³⁺ by losing 3 electrons.Likewise, Cl is in 17th group of the periodic table and forms Cl⁻ by gaining one electron. Hence aluminiumchloride can be written as AlCl₃.

Cs is in 1st group ofthe periodic table. Hence, Cs tends to form Cs⁺ by losing an electron.

The reaction between Cs⁺ and Cl⁻ will form CsCl.

Since, this is a single replacement reaction, Al inthe AlCl₃ is replaced by Cs andCsCl is formed. The balancedreaction equation is

AlCl₃ + 3Cs → 3CsCl + Al

Answer 2

Answer: The answer is c. AlCl3 + 3Cs -> Al + 3CsCl. First you already know this reaction is a single replacement reaction. And next, the Al ion is usually +3, Cs ion is usually +1.

How do valence electrons affect reactivity?

Answers

The less valence electrons there are, the less stable the atom becomes, causing it to react with other atoms. More valence electrons adds mass to the atom, making it less reactive

A sample of gas at 300 K has a volume of 2.0 liters. At what temperature will the volume decrease to 1.0 liter if the pressure is kept constant?

Answers

Answer : The temperature will be, 150 K

Explanation :

Charles' Law : This law states that volume of gas is directly proportional to the temperature of the gas at constant pressure and number of moles.

$V\propto T$ (At constant pressure and number of moles)

or,

$(V_1)/(T_1)=(V_2)/(T_2)$

where,

$V_1$ = initial volume of gas = 2.0 L

$V_2$ = final volume of gas = 1.0 L

$T_1$ = initial temperature of gas = 300 K

$T_2$ = final temperature of gas = ?

Now put all the given values in the above formula, we get the final temperature of gas.

$(2.0L)/(300K)=(1.0L)/(T_2)$

$T_2=150K$

Therefore, the temperature will be, 150 K

pv/t=c
Therefore

v/t=c
2/300=1/t2
t2=150K

Which of the following is represented in the highest percentage by volume in dry air?a. Carbon dioxide
b. Oxygen
c. Hydrogen
d. Nitrogen

Answers

Answer: The correct answer is Option d.

Explanation:

Dry air is composed of a mixture of gases like argon, oxygen, nitrogen, carbon dioxide and many other gases present in trace amount.

The percentage of these gases by volume in dry air is:

Carbon dioxide = 0.03%

Argon = 0.93%

Oxygen = 20.95%

Nitrogen = 78.09%

Hydrogen = Trace amounts

From the above percentage values, we can easily say that nitrogen has the highest percentage by volume in dry air. Hence, the correct option is d.

nitrogen is the highest percent of 93%

Calculate the molar mass of cacl2

Answers

Answer:

$\boxed {\boxed {\sf 110.98 \ g/mol}}$

Explanation:

The molar mass is the mass of a substance in grams per mole.

To find it, add the mass of each element in the compound. These masses can be found on the Periodic Table.

The compound given is:

$CaCl_2$

The compound has 1 Ca (calcium) and 2 Cl (chlorine).

Mass of Calcium

The molar mass of calcium is 40.08 g/mol
There is only one atom of Calcium in CaCl₂, so the number above is what we will use.

Mass of Chlorine

The molar mass of chlorine is 35.45 g/mol
There are two atoms of chlorine in CaCl₂, therefore we need to multiply the molar mass by 2.
35.45 * 2= 70.9 g/mol

Molar Mass of CaCl₂
