The correct answer would be the second option. The outcome of a fusion reaction which involves isotopes of hydrogen would be the nuclei of the hydrogen isotopes join together to form a heavier element, and energy is released. A fusion reaction is a nuclear reaction which involves at least two nuclei or atoms combining forming products that are heavier than the reactants. Along with the formation of a new atomic nuclei, energy is released. Fusion of two isotopes of hydrogen, specifically deuterium and tritium, results to the formation of a neutron and a helium-3 atom atom. This reaction happens in the core of the Sun.
The rubbing creates a negative charge that is carried by electrons. The electrons can build up t produce static electricity.
Answer:
The work is -6,497.54 J
Explanation:
Work is the amount of energy transferred from one system to another by a force when a displacement occurs.
The work exchanged for a gas depends on the transformation it performs to go from the initial state to the final state.
The pressure - volume work done by a system that compresses or expands at constant pressure is given by the expression:
W= -P*ΔV
where
- W is the work exchanged by the system with the environment. Its unit of measure in the International System is the joule (J), which is equivalent to Pa*m³
- P: Pressure. Its unit of measurement in the International System is the pascal (Pa).
- ∆V: Volume variation (∆V = Vfinal - Vinitial). Its unit of measurement in the International System is cubic meter (m³)
In this case:
- Wsystem=?
- P= 5.63 atm=570,459.8 Pa (being 1 atm=101325 Pa)
- ΔV=Vfinal - Vinitial= 15.61 L - 4.22 L= 11.39 L= 0.01139 m³ (being 1 L=0.001 m³)
Replacing:
W= -570,459.8 Pa*0.01139 m³
Solving:
W=-6,497.54 J
<u><em>The work is -6,497.54 J</em></u>
Original Recipe
1 (18 1/4 ounce) Box devils food cake mix
1/2 cup vegetable oil
2 large eggs
Confectioners' Sugar (for rolling)
Directions:
Preheat oven to 350 degrees. Stir (by hand) cake mix, oil, and eggs- until dough forms. Dust with sugar and shape into 1 inch balls. Roll balls in sugar and place on ungreased cookie sheet. Bake 8-10 minutes. Remove from pan after one minute and put on cooling rack.
Cooking for 17 people
My original yield was 30 cookies.
17 cookies (1box cake mix/30 cookies)= .56 of a box= 1/2 box
17 cookies (1/2 cup oil/30 cookies)= .283 cups of oil= 1/4 cups
17 cookies (2 eggs/30 cookies)= 1.13 eggs= 1 egg
Percent Yeild
I was able to bake 24 cookies, with my original yeild being 30.
(24 cookies/30 cookies) x 100= 80% yeild
