1. Concentrația procentuală a unei soluții 4M de NaOH cu densitatea 1,25g/ml esteNa-23, O-16, H-1. 2. O soluție de hidroxid de sodiu cu volumul de 300 ml și concentrația 0,1 M se amestecă cu 0,1 L soluție dehidroxid de sodiu, de concentrație 0,2 M și cu 100 ml apă distilată. a. Calculați cantitatea de hidroxid de sodiu, exprimată în moli și grame, din soluția rezultată după amestecare. b. Determinați concentrația molară a soluției de hidroxid de sodiu obținută după amestecare. Na-23, O-16, H-1

a. a clone will be physically identical to the original, but won’t be genetically identical

have a good day!

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:

answer: the primary difference between a hypothesis and a theory is that b hypothesis is falsifiable, but a theory has been proven to be correct. theory is an explanation of something that is happening but hypothesis is a guess of something that can happen

explanation:

i believe that it is a exoplanet
