A student dissolves 11.6 g of sodium hydroxide (NaOH) in 250.g of water in a well-insulated open cup. He then observes the temperature of the water rise from 23.0 °C to 35.5 °C over the course of 4.4 minutes. Use this data, and any information you need from the ALEKS Data resource, to answer the questions below about this reaction: NaOH(s) Na (aq) + OH (aq) You can make any reasonable assumptions about the physical properties of the solution. Be sure answers you calculate using measured data are rounded to the correct number of significant digits. Note for advanced students: It's possible the student did not do the experiment carefully, and the values you calculate may not be the same as the knows and published values for this reaction. O exothermic Is this reaction exothermic, endothermic, or neither? endothermic X 5 ? neither If you said the reaction was exothermic or endothermic, calculate the amount of neat that was released or absorbed by the reaction in this case. Calculate the reaction enthalpy AW per mole of NaOH.

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.  

explanation:

the answer is a and have a great day

since electrons are negative the answer is neagtaive
