i know the final answer, but i need an explanation with steps how we get .11 in the end by using the standard normal distribution (z-table) Example (continued) Notice that $1.50/V50 is about .212. This is the standard deviation for i Then $7.25 is about .257.212=1.179 standard deviations away from the average and $7.5 is about 2.357 std. dev, away. We can find the probability of a value being between 1.179 and 2.357 standard deviation away from the average. It...
Epistemology addresses the question of how we know, that is, how do we know reality. In your opinion is an inductive or deductive approach to knowing reality better?

Could someone please explain to me how we get to this answer? I know (Ecell = Ecathode − Eanode) Co(s) Co2+ (aq) || Sn2+ (aq) | Sn(s) has a standard cell potential of 0.14 V. Co2+ (aq) + 2e → Co(s) has a standard reduction potential of -0.28 V. What is the standard reduction potential of Sn2+ (aq) + 2e → Sn(s)? a. None of the other options are correct b. -0.14 V c.-0.42 v d. 0.14 V e. 0.42...
I need help with the acids and bases unit. how would I get the hydronium ion concentration from volume and pH. how do I get pOH from hydronium ions how do I get pH when I have Concentration if chemicals have the same molarity how would I know which is a stronger acid (they aren't in data book) how would I know which is more conducive to least how would I know which has a higher OH- concentration
I would like to know the answer for #12 and how to get the value for #12.. QUESTION 10 You are instructed to make a buffer solution of pH = 4.5. Assume that the buffer solution is made by mixing a volume of a 0.100 M acetic acid solution and a 0.100 M sodium acetate solution. Determine the volume (in mL) of acetic acid required to prepare 60.0 mL of your assigned buffer pH. 38.1 QUESTION 11 Based on the...
How would we work this out? I know the answer is 4.89 44) In the titration of 10.00mL of a 0.15M acetic acid solution (Ka 1.8 x 10-5) with 0.25M sodium hydroxide, what is the pH after 3.50 mL of the base has been added? a) 4.59 b) 4.69 c) 4.79 d) 4.89 e) 4.99
I know how to solve the rest of this problem but I dont understand how we get this equation to start with 4. Calculate the pH after 0.013 mol of gaseous HCl is added to 260.0 mL of the following buffered solution (Kb, NHB 1.76 x 10) 0.22 M NH3 and 0.45 M NH4Br
How do we know if photosynthesis or cellular respiration is occurring in our experiment? How do we determine the progress in this experiment?(Hint: What would be the dependent variable(s) of our experiment?)
