Acylinder and piston assembly (defined as the system) is warmed by an external flame. the contents of the cylinder expand, doing work on the surroundings by pushing the piston outward against the external pressure. if the system absorbs 533 j of heat and does 488 j of work during the expansion, what is the value of δe? express the energy change as an integer and include the appropriate units.

The energy change for the given system: ΔE  = 45 J

Explanation:

According to the First Law of thermodynamics, the energy can't be created or destroyed and can only be converted into other forms.

ΔE = Q - W                                 equation 1

Given: ΔE is the change in the internal energy

Q is the heat absorbed by the system

W is the work done by the system

Given: Q = = 533 J, W = 488 J, ΔE = ?

Using equation 1, to calculate the change is the internal energy (ΔE),

ΔE = Q - W = 533 J - 488 J = 45 J

Therefore, the energy change for the given system: ΔE  = 45 J

- "the acute form of diverticulitis can manifest itself with one or more severe attacks of infection and inflammation.

the inflammation of diverticulitis can eventually result in a bowel obstruction, which may cause constipation, thin stools, diarrhea, abdominal swelling or bloating, and abdominal pain."

1.consider the following balanced equation and answer parts a through. show calculations for each part.  

3 ag(s) + 4 hno3(aq) → 3 agno3(aq) + no(g) + 2 h2o(l)  

a. calculate the number of moles of agno3 produced by the reaction of 3 moles of ag with excess hno3. if the number to the left of the compound represents the number of moles of the compound which are present, then 3 moles of ag react with 4 moles hno3 to produce 3 moles agno3 (aq).

so the answer to a would be 3 moles.

b. calculate the number of moles of agno3 produced by the reaction of 108 grams of ag with excess hno3.  

i'm not sure how to plug in the grams of silver into an equation using moles to find how many moles are produced.

c. calculate the number of grams of agno3 produced by the reaction of 108 grams of ag with excess hno3  

d. calculate the number of moles of no produced as a byproduct of the reaction of 108 grams of ag with excess hno3.  

e. calculate the number of grams of no produced as a byproduct starting with 108 grams of ag and excess hno3.
