The following balanced equation shows the formation of sulfur dioxide. S + O2 mc023-1.jpg SO2 How many moles of sulfur are needed to produce 15.0 mol of sulfur dioxide?

Answers

Answer 1

Answer:

For the given chemical reaction, 15 moles of sulfur are required to produce 15 moles of sulfur dioxide.

What is the balanced chemical equation?

A chemical equation can be defined as a representation of a chemical reaction in the form of symbols of the substances. A chemical equation consists of contributing reactants in the reaction, formed products, and their physical states.

The chemical equation in which the number of atoms of each element is equal on both sides of the equation is called a balanced chemical equation.

The law of conservation of mass follows by a balancing of a chemical equation therefore, the total mass of the elements on the reactant side must be equal to the total mass of elements on the product side.

Given, the chemical equation is: S + O₂ → SO₂

From the above equation, we can say that one mole of sulfur produces one mole of sulfur dioxide.

Given the moles of the sulfur dioxide = 15 moles

The moles of sulfur required to make 15 moles of sulfur = 15 moles

Therefore, 15 moles of sulfur are required for the given conditions.

Answer 2

Answer: S + O₂ = SO₂

1 mole S ------------ 1 mole SO₂
? mole S ----------- 15.0 mole SO₂

S = 15.0 * 1 / 1

= 15 moles of S

hope this helps!

The enthalpy change for dissolving this salt on a energy per mass is 136.32 J/g

How to determine the mass of the water

Density of water = 1 g/mL
Volume of water = 75 mL
Mass of water =?

Mass = Density × Volume

Mass of water = 1 × 75

Mass of water = 75 g

How to determine the heat absorbed by the solution

Mass of water = 75 g
Mass of salt = 2.50 g
Mass of solution (M) = 75 + 2.5 = 77.5 g
Temperature change (ΔT) = 0.93 °C
Specific heat capacity of the solution = 4.184 J/gºC
Heat of solution (Q) =?

Q = MCΔT

Q = 77.5 × 4.184 × 0.93

Q = 301.5618 J

How to determine the heat consumed by the calorimeter

Heat capacity of the calorimeter (C) = 42.2 J/ºC
Temperature change (ΔT) = 0.93 °C

Heat by calorimeter (H) =?

H = CΔT

H = 42.2 × 0.93

H = 39.246 J

How to determine the total heat released

Heat of solution (Q) = 301.5618 J
Heat by calorimeter (H) = 39.246 J

Total heat =?

Total heat = 301.5618 + 39.246

Total heat = 340.8078 J

How to determine the enthalpy change

Total heat = 340.8078 J
Mass of salt = 2.5 g

Enthalpy change (ΔH) =?

ΔH = Total heat / mass

ΔH = 340.8078 / 2.5

ΔH = 136.32 J/g

Answer : The enthalpy change for dissolving this salt on a energy per mass basis is 132.4 J/g

Explanation :

Heat released by the reaction = Heat absorbed by the calorimeter + Heat absorbed by the water

$q=[q_1+q_2]$

$q=[c_1* \Delta T+m_2* c_2* \Delta T]$

where,

q = heat released by the reaction

$q_1$ = heat absorbed by the calorimeter

$q_2$ = heat absorbed by the water

$c_1$ = specific heat of calorimeter = $42.2J/^oC$

$c_2$ = specific heat of water = $4.184J/g^oC$

$m_2$ = mass of water = $Density* Volume=1/mL* 75.0mL=75.0g$

$\Delta T$ = change in temperature = $0.93^oC$

Now put all the given values in the above formula, we get:

$q=[(42.2J/^oC* 0.93^oC)+(75.0g* 4.184J/g^oC* 0.93^oC)]$

$q=331.08J$

Now we have to calculate the enthalpy change for dissolving this salt on a energy per mass basis.

$\Delta H=(q)/(m)$

where,

$\Delta H$ = enthalpy change = ?

q = heat released = 331.08 J

m = mass of salt = 2.50 g

$\Delta H=(331.08J)/(2.50g)=132.4J/g$

Therefore, the enthalpy change for dissolving this salt on a energy per mass basis is 132.4 J/g

Answers

Answer:

1. B Decantation. 2. D 3. B

Explanation:

This method is often used when dealing with mixtures of liquids or immiscible liquids with different densities

2. This is because the denser substance sinks to the bottom due to its higher density, while the less dense substance remains on the surface. It allows for the separation of the two substances based on their density.

3. The mixture is left undisturbed after the less dense substance has been poured off. This allows the denser substance to settle at the bottom while the lighter substance remains on top

4. It's a handy method for separating substances based on their density For example, if you have a mixture of oil and water, you can use decantation to separate the two. By letting the mixture sit undisturbed, the oil, being less dense, will float to the top, allowing you to carefully pour it off and separate it from the water.

Which diatomic molecule is formed when thetwo atoms share six electrons?
(1) H2
(2) N2
(3) O2
(4) F2

Answers

Answer: (2) $N_2$

Explanation:

1) $H_2$ is a diatomic molecule which is formed by sharing of two electrons between two hydrogen atoms.

2) $N_2$ is a diatomic molecule which is formed by sharing of six electrons between two nitrogen atoms.

3) $O_2$ is a diatomic molecule which is formed by sharing of four electrons between two oxygen atoms.

4) $F_2$ is a diatomic molecule which is formed by sharing of two electrons between two fluorine atoms.

I believe the correct answer from the choices listed above is option 2. The diatomic molecule that is formed when the
two atoms share six electrons would be N2. It has five valence electrons, so it needs three more valence electrons to complete its octet.
