Answer:
When a reduction reaction and an Oxidation reaction takes place due to passing of current through water the molecules of water split into the compounds. Where it is made up of hydrogen in its state of gas and also Oxygen in its state of gas this method is most vastly is known as electrolysis.
In this process a certain direct current is passed from inside water. This direct current value can be near about 1.23 voltages the reaction that happens inside is given below.
2 Water---> Oxygen + 4 hydrogen ions + 4 Electrons
2 Hydrogen ions + 2 electrons ----> hydrogen gas
Answer:
Mass of paraffin that would be needed to collect the amount of energy as 4.73 x 10³ kg of water is 6.85 * 10³ kg
Explanation:
Specific heat capacity of paraffin, Cp = 2.90 J/g.°C = 2900 J/kg.°C
Specific heat capacity of water = 4.20 J/g.°C = 4200 J/kg.°C
Amount of heat energy that can be stored by 4.73 * 10³ kg of water heated through a degree rise in temperature can be calculated as below:
Using H = mCpθ where m is mass of substance, Cp is specific heat capacity and θ is temperature change
H = 4.73 * 10³ kg * 4200 J/kg.°C * 1°C
H = 19866000 J
Mass of paraffin that would be needed to collect the amount of energy as 4.73 x 10 3 kg of water for a degree rise in temperature is calculated as follows:
H = mCpθ
19866000J = m * 2900 J/kg.°C * 1°C
m = 19866000J / 2900 J/kg
m = 6850.34 kg = 6.85 * 10³ kg
Therefore, mass of paraffin that would be needed to collect the amount of energy as 4.73 x 10³ kg of water is 6.85 * 10³ kg
Idk but you can try to look it up. On google or somewhere else but yea idk about that one
Answer:
Formation of Gas
Explanation:
The solid Carbon Dioxide warms it sublimates to gas. With limited room for the gas to expand, the pressure in the bottle increases.
