Hey there!
I believe the answer is Combination (or Synthesis) Reaction.
Answer:
the correct answer is CO2 (the last one)
Answer:
- 278.85 J
Explanation:
Given that:
Pressure = 1.1 atm
The initial volume V₁ = 0.0 L
The final volume V₂ = 2.5 L
The work that takes place in a reaction at constant pressure can be expressed by using the equation:
W = P(V₂ - V₁ )
Since the volume of the gas is expanded from 0 to 2.5 L when 1.1 atm pressure is applied. Then, the work can be given by the expression:
W = - P(V₂ - V₁ )
W = -1.1 atm ( 2.5 - 0.0) L
W = -1.1 atm (2.5 L)
W = -2.75 atm L
Recall that:
1 atm L = 101.4 J
Therefore;
-2.75 atm L = ( -2.75 × 101.4 )J
= -278.85 J
Thus, the work required at the chemical reaction when the pressure applied is 1.1 atm = - 278.85 J
Energy and mass equivalence
Explanation:
The law of conservation of energy does not apply to nuclear reactions, the law of conservation of mass-energy makes more sense in this regard.
In nuclear reactions mass is transformed into energy. Therefore, it does not conform with the law of conservation of energy.
- According to the law of conservation of energy "energy is neither created no destroyed but they are transformed from one form to another. "
- In nuclear reactions, mass is usually lost. Mass is not conserved.
- But, the mass is converted into energy and we say there is mass and energy equivalence for nuclear reactions.
