Consider the following reaction, which occurs at standard state:
2CI(g) -- CI2(g) H= -243.4 kJ
If 15.0g of CI is concerted to chlorine, determine the heat released from this reaction.

Answers

Answer:

The heat energy released from the reaction is approximately 51.4791 kJ

Explanation:

The given parameters are;

The heat of the reaction of 2Cl (g) → Cl₂ (g) = -243.4 J

The given mass of Cl being converted to chlorine gas, Cl₂ = 15.0 g

From the reaction for the heat of formation, we have;

2 moles of chlorine produces 1 mole of Cl₂ to release 243.4 kJ of energy per mole of Cl₂

The mass of 1 mole of Cl ≈ 35.453 g

Therefore, from number of moles, n = Mass/(Molar Mass), we have;

The number of moles of chlorine, in 15.0 g of chlorine = 15.0/35.453 ≈ 0.423 moles

Therefore, given that 2 moles of Cl produces 1 mole of Cl₂, we have;

0.423 moles of Cl will produce 0.423/2 ≈ 0.2115 moles of Cl₂

The heat energy released from the reaction is therefore, H ≈ 0.2115 × 243.4 kJ = 51.4791 kJ.

A compound is determined to have the empirical formula C2OH4. If the molar mass of the compound is 132 g/mol, determine the molecular formula of the compound.

Answers

Answer: The molecular formula will be [tex]C_6O_3H_{12}[/tex]

Explanation:

Molecular formula is the chemical formula which depicts the actual number of atoms of each element present in the compound.  

Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.  

Empirical weight of [tex]C_2OH_{4}[/tex] is [tex]12\times 2+16\times 1+1\times 4=44g[/tex]

Molecular mass of compound is = 132 g

Now we have to calculate the molecular formula.

[tex]n=\frac{\text{Molecular weight}}{\text{Equivalent weight}}=\frac{132}{44}=3[/tex]

The molecular formula will be=[tex]3\times C_2OH_4=C_6O_3H_{12}[/tex]

1.32*10^23 molecules

Explanation:

sucrose formula: C12H22O11

molar mass: 12(12.01)+22(1.01)+11(16.00)=342.34g/mol

75.0 g C12H22O11 * (1 mol C12H22O11)/(342.34g C12H22O11)=0.219 mol C12H22O11

0.219 mol * (6.022*10^23)/mol = 1.32*10^23 molecules (three sig. figures)

A compound was analyzed and found to contain the following percent composition: 2.056% hydrogen, 32.69% S, and 65.26% oxygen. Calculate the empirical formula.

Answers

Answer:

H2SO4

Explanation:

Firstly,

2.056% hydrogen = 2.056g of H

32.69% Sulphur = 32.69g of S

65.26% oxygen = 65.26g of O

Next, we convert each mass into moles by dividing by their respective molar mass:

H = 1, S = 32, O = 16

H = 2.056/1 = 2.056mol

S = 32.69/32 = 1.021mol

O = 65.26/16 = 4.078mol

Next, we divide each mole value by the smallest mole value (1.021)

H = 2.056/1.021 = 2.01

S = 1.021/1.021 = 1

O = 4.078/1.021 = 3.99

Approximately the ratio of H to S to O is 2:1:4, hence, the empirical formula for H, S and O is H2SO4.

The empirical formula of a chemical compound is the simplest whole-number ratio of atoms present in a compound

The correct answer of the following is [tex]H_2SO_4[/tex]

The data is given as follows:-

2.056% hydrogen = 2.056g of H 32.69% Sulphur = 32.69g of S65.26% oxygen = 65.26g of O

We have to find the moles in the reaction.

The mas of the element is as follows:-

H = 1S = 32O = 16

After solving the equation we get

[tex]H = \frac{2.056}{1} = 2.056mol\\\\S = \frac{32.69}{32} = 1.021mol\\\\O = \frac{65.26}{16} = 4.078mol[/tex]

Next, we divide each mole value by the smallest mole value (1.021)

[tex]H = \frac{2.056}{1.021} = 2.01\\\\S = \frac{1.021}{1.021} = 1\\\\O = \frac{4.078}{1.021} = 3.99[/tex]

The ratio of H to S to O is 2:1:4,

Hence, the empirical formula for H, S, and O is [tex]H_2SO_4.[/tex]

The beakers in the picture above are labeled according to the ionic solutions they contain. What metal or metals could replace copper in the copper(II) nitrate solution?

Answers

Explanation:

When a metal replaces another metal in solution, we say such a reaction has undergone a single displacement reaction.

In such a reaction, metal higher up in the activity series replaces another one due to their position.

To known the metal or metals that will replace the given copper, we need to reference the activity series of metals.

Every metal higher than copper in the series will displace copper from the solution.

So, there metals are: potassium, sodium, lithium, barium, strontium etc.

Nistu is cooking rice in a pot. When she leaves the pot on the stove for a while, the temperature of the rice increases. What happens to the molecules of the rice when the temperature of the rice increases?

Answers

Answer:

Their average kinetic energy increases

Explanation:

The average kinetic energy of the rice molecules increases as the pot is left on the cooking stove.

Heat is transferred to the pot by conduction from the heat source. The heat is then transferred to the rice in the cooking pot by convection.

As the water in the pot heats up. The rice gains thermal energy. This causes the molecules of the rice particles to start vibrating. As the molecules vibrate about their fixed position, their thermal energy continues to increase.Therefore, the amount of heat absorbed by the rice increases with time and this actually cooks the food.

Answer:

The energy of the molecules in the rice increases.

Explanation:

Typically protons cannot be removed from the atom. Removing protons from an atom will completely change the atom as it will become another element entirely.

In an atom, protons are held by strong nuclear forces.

Within an atom, protons are the positively charged particles. Together with the neutrons, they are found in the nucleus of an atom. The number of protons within an atom is the atomic number of the atoms and it determines the nature and type of atom it is. Protons cannot be removed from an atom due to the strong binding force holding them together in place.
