Agas is confined to a cylinder under constant atmospheric pressure, as illustrated in
figure 5.4. when 0.49 kj of heat is added to the gas, it expands and does 214 j of work
on the surroundings. what are the values of ∆h and ∆e for this process?
delta h is the main issue i'm having trouble understanding.
water is used to store them because it would keep the radiation from getting out in the open and causing harm to the workers
zfoods? ok, pressure is used to keep the heat inside and to keep the food perfect.
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.
beta decay is the answer
