Explanation:
100 liter because it is measured
Answer:
Energy change = 59. 5 kJ
Explanation:
First, we collect the data:
Let:
Q (supplied) be the energy supplied to the water
Q (lost) be energy lost to surroundings
Q (piston) be the energy possessed by the piston as it moves up
v = volume flow (m³/s)]
V = velocity of the gas (m/s)
mass = 50 kg
Second, calculate the work done by the piston:
to find velocity, we use this formula:
v = A × V
Therefore, V = 0.5 (m³/s)/0.005 m²
= 10 m/s
it means the water is evaporating at a rate of 10 m/s
the evaporating water transfers energy to the piston, kinetic energy Ek
Ek = 1/2 mV²
= 0.5 (50) ( 10) ²
= 2 500 J
= 2.5 kJ
The net energy, ΔQ is given by:
ΔQ (net) = Q (supplied) - Q (piston) - Q (lost)
= 70 - 2.5 -8
=<u> 59.5 kJ Ans</u>
This is the answer
P > S > Si > Al
Phosphorus is in group 15 and sulfur is in group 16 so the ionization energies is a little bit lower the phosphorus.
Answer :
is reduced species.
is oxidized species.
is oxidizing agent.
is reducing agent.
Explanation :
Redox reaction or Oxidation-reduction reaction : It is defined as the reaction in which the oxidation and reduction reaction takes place simultaneously.
Oxidation reaction : It is defined as the reaction in which a substance looses its electrons. In this, oxidation state of an element increases. Or we can say that in oxidation, the loss of electrons takes place.
Reduction reaction : It is defined as the reaction in which a substance gains electrons. In this, oxidation state of an element decreases. Or we can say that in reduction, the gain of electrons takes place.
Reducing agent : It is defined as the agent which helps the other substance to reduce and itself gets oxidized. Thus, it will undergo oxidation reaction.
Oxidizing agent : It is defined as the agent which helps the other substance to oxidize and itself gets reduced. Thus, it will undergo reduction reaction.
The balanced redox reaction is :
The half oxidation-reduction reactions are:
Oxidation reaction : 
Reduction reaction : 
From this we conclude that the 
is the reducing agent that loses an electron to another chemical species in a redox chemical reaction and itself gets oxidized and 
is the oxidizing agent that gain an electron to another chemical species in a redox chemical reaction and itself gets reduced.
Thus, is reduced species.
is oxidized species.
is oxidizing agent.
is reducing agent.
