The mass of sulfurous acid produced when 245g of sulfur dioxide is reacted with water is 313.8 g
StoichiometryFrom the question, we are to determine the mass of sulfurous acid produced
First, we will write the balaced chemical equation for the reaction
H₂O + SO₂ → H₂SO₃
This means 1 mole of H₂O reacts with 1 mole of sulfur dioxide (SO₂) to produce 1 mole of sulfurous acid (H₂SO₃)
Now, we will determine the number of moles of sulfur dioxide present
Mass of sulfur dioxide present = 245 g
Molar mass of sulfur dioxide = 64.066 g/mol
Using the formula,
[tex]Number \ of \ moles = \frac{Mass}{Molar\ mass}[/tex]
Then,
Number of moles of SO₂ present = [tex]\frac{245}{64.066}[/tex]
Number of moles of SO₂ present = 3.824 moles
This is the number of moles of SO₂ present
From balanced chemical equation
1 mole of H₂O reacts with 1 mole of sulfur dioxide (SO₂) to produce 1 mole of sulfurous acid (H₂SO₃)
Then,
Water (H₂O) will react with the 3.824 moles of sulfur dioxide (SO₂) to produce 3.824 moles of sulfurous acid (H₂SO₃)
∴ The number of moles of sulfurous acid produced is 3.824 moles
Now, for the mass of sulfurous acid produced
Molar mass of sulfurous acid = 82.07 g/mole
Using the formula,
Mass = Number of moles × Molar mass
Mass of sulfurous acid produced = 3.824 × 82.07
Mass of sulfurous acid produced = 313.8 g
Hence, the mass of sulfurous acid produced is 313.8 g

A chemical supply company sells sulfuric acid (H3CS06) in a concentration of 4.00 M. What volume of this solution would you need to make 12.0 mL of a 0.50 M H2SO4 s…
Molarity is the ratio of a mole of the solute of the substance to the liter of solution. The volume of solution required to make 12.0 ml of 0.50 M solution is 1.5 mL.
What is molar dilution?Molar dilution is the calculation of the molarity or the volume of the unknown value from the known value. It is given as,
[tex]\rm M_{1}V_{1}= \rm M_{2}V_{2}[/tex]
Given,
Initial molarity = 4.00 M
Initial volume =?
Final molarity = 0.50 M
Final volume = 12.0 mL
Substituting values in the equation:
[tex]\begin{aligned} \rm V_{1} &= \rm \dfrac{\rm M_{2}V_{2}}{M_{1}}\\\\&= \dfrac{0.50 \times 12.0 }{4.00}\\\\&= 1.5 \;\rm ml\end{aligned}[/tex]
Therefore, 1.5 ml of 4.00 M sulfuric acid must be used to make 12 ml of 0.50 M solution.

In an experiment using a calorimeter, the following data was obtained:
Mass of calorimeter + water .............150g
Mass of calorimeter ……………………...100g
Final temperature of water …………… 55oC
Initial temperature of water …………. 25oC
What is the total number of Joules absorbed by the water?
Based on the data provided from the experiment using the calorimeter, the heat absorbed by water is 188.1 Joules
What is a calorimeter?A calorimeter is an equipment used in the laboratory to enthalpy change of a reaction.
A calorimeter is insulated to ensure no heat losses or gain from the surroundings.
To determine the Joules of heat absorbed by water, the formula below is used:
Heat absorbed = mass × specific heat capacity × temperature differenceSpecific heat capacity of water = 4.18 J/g.°C
Heat absorbed by water = 15 × 4.18 × (55 - 25)
Heat absorbed by water = 188.1 Joules
Therefore, the heat absorbed by water is 188.1 Joules.

Carson’s class visited a hydroelectric plant on a field trip during their study of energy. The process interested him, and he had the chance to observe it in action. Explain how moving water generates electrical power, and describe where it goes.
Answer:
look in your science book
Explanation:
Hydroelectricity or hydroelectric power is the electricity generated from hydropower. It is the Hydropower which supplies one sixth of the worlds electricity. Here water in motion is used to generate the electricity.
How water generates electricity?Hydroelectricity is produced by utilizing the gravitational force of moving water. Hydropower plant requires a dam. The dam is a massive wall that blocks the flow of the river, therefore a lot of water collects behind the dam. Near bottom of the dam, there is an intake from which water is left into the dam.
The device which is used to obtain energy from the moving water is called the turbine. The turbine is connected by a shaft to the generator. When the water rotates the turbine, electrical energy is generated.
Hydropower plants also have a pumped storage where the water is kept as a reserve for periods of peak power demand.
