When mixing HCl(aq) and NaOH(aq) of the same concentration (1.0 m) to produce 100 mL of product solution what volume ratio produces the largest temperature change

See explaination

Explanation:

We have to understand the reason of temperature change , when NaOH reacts with HCl neutralization reaction occurs producing energy. When this released energy is absorbed temperature is increased.

So when 1 mole off NaOH reacts with 1 mole of HCl reacts 57.3 KJ of energy is released .

During a reaction for , when equivalent number of moles reacts higher energy will be produced.

If 80 ml HCl and 20 ml NaOH reacts , then only 20 ml NaOH reacts with 20 ml of HCl and rest 60 ml is not reacting.

But when 60 ml HCl and 40 ml NaOH reacts 40 ml of each are reacting, so energy produced will be higher.

so B > A

For II the observed phenomena is already discussed as higher number of moles of HCl and NaOH reacts so , due to which higher energy is released and thus temperature is higher.

50 ml of each HCl and NaOH produces largest temperature change , as higher number of moles of HCl and NaOH reacts so , due to which higher energy is released and thus temperature is higher.

the answer is d : ) have a good da

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.
