1.64 L of sulfur dioxide (SO₂)

Explanation:

We have the following chemical reaction:

S (s) + O₂ (g) → SO₂ (g)

First we calculate the number of moles of sulfur (S):

number of moles = mass / molar weight

number of moles of sulfur = 2.35 / 32 = 0.0734 moles

Looking at the chemical reaction we see that 1 moles of sulfur (S) produces 1 moles of sulfur dioxide (SO₂), so 0.0734 moles of sulfur will produce 0.0734 moles of sulfur dioxide (SO₂).

To calculate the volume of sulfur dioxide (SO₂), assuming that the sulfur dioxide is behaving as an ideal gas and the we determine the gas volume under standard temperature and pressure conditions, we use the following formula:

number of moles = volume / 22.4 (L/mole)

volume = number of moles × 22.4

volume of SO₂ = 0.0734 × 22.4 = 1.64 L

A 10-gram sample of zinc loses 560 J of heat and has a final temperature of 100
grandymaker [24]
<h3>Answer:</h3>

Initial temperature is 243.59°C

<h3>Explanation:</h3>

The quantity of heat is calculated by multiplying the mass of a substance by its specific heat capacity and change in temperature.

That is; Q = m×c×ΔT

In this case;

Quantity of heat = 560 J

Mass of the Sample of Zinc = 10 g

Final temperature = 100°C

We are required to determine the initial temperature;

This can be done by replacing the known variables in the formula of finding quantity of heat,

Specific heat capacity, c, of Zinc = 0.39 J/g.°C

Therefore,

560 J = 10 g × 0.39 J/g°C × ΔT

ΔT = 560 J ÷ (3.9 J/°C)

   = 143.59°C

But, since the sample of Zinc lost heat then the temperature change will have a negative value.

ΔT = -143.59°C

Then,

ΔT  = T(final) - T(initial)

Therefore,

T(initial) = T(final) - ΔT

              = 100°C - (-143.59°C)

              = 243.59°C

Hence, the initial temperature of zinc sample is 243.59°C

A force of 30 N is applied to a screwdriver to pry the lid off of a can of paint. The screwdriver applies 75 N of force to the l
Ipatiy [6.2K]
The formula of mechanical advantage in this situation is:
MA = Input Force ÷ Output Force

The input force is the 30N applied to a screwdriver while the output force is the 75N force to the lid.

So,

MA = 30N/75N
MA = 0.40

Hence the mechanical advantage of the screwdriver is 0.40.

Which is the average kinetic energy of the individual particles of a substance?
zhannawk [14.2K]

Answer: Temperature

Explanation: Temperature is a measure of average kinetic energy of particles in an object. The hotter the substance, higher is the average kinetic energy of its constituent particles. When we heat a substance, the particles that constitute the substance gain some energy and begin to move faster.
