How do you evaluate this log?? I know the formula is logb?(a) = x such that bx? = a..
we know that, according to logarithm properties blogbp = p
in the same way 2log2(n+1/n+2)= n+1/n+2 is the answer

How do you find the limiting reactant? I know the formula, but I cant remember how to round the moles to a whole number. 9 064g Imol = 1.88x10th mol 340.19 reactant 1 (E-stilbenel o.osog 1 mol = 2.77 x 16 mol 1180.2g B reactant 2 (pyridinium tribromide) O. 10lg mil Imol - 3.16 *10 1319.99 Limiting Reactant A reactant & B reactant -> C Product
n)2" log log(n)O(n)? I don't How does =n. VIn) T n understand how VITn) 2" log 7 -)? I know we can take out the T, because 1) Vn) T* n it's in our natural logarithm. It's a constant factor. but how does (n) show up in the denominator after it used to be in the numerator? I need to know how the expression (1) right on the left is equal to the expression (1) on the n)2" log log(n)O(n)?...
Can I know how to do part(c)? I know how to do (a)(b). By (a) and (b), I get this 4 results. 1. ▾.F = 2xz5-2xz+3xz2 2. ▾xF = (2xy) i + (5x2z4-z3) j -(2yz) k 3. ▾.(▾xF) = 0 4. ▾x(▾f) = 0 Next, i need to calculate part (c). I want the solution of part(c), so don't give me the result of part(a) and (b) again, thanks! 1. (25 marks) (a) Evaluate . F and V. (V x...
How do I solve 6.57 = 2 + log [0.125]/[H3PO4]? I know the answer is supposed to be [H3PO4] = 3.38X10^-6 M, but how do I get there? PLEASE SHOW ALL STEPS
I got x=0.011 and I know that -log(0.011)= the pH that is the answer but how do i know that i use 0.011 and why do i not divide 1.01x10^-14 by that like I do in different problems, or why do i not substitute the x back into the 0.5-x? 26) Farmers who raise cotton once used arsenic acid, H3 AsO4, as a defoliant at harvest time. Arsenic acid is a polyprotic acid with Kal = 2.5 x 10-4, Ka2...
I know how to do the question, but at the very end, how do you know if it's a buffer or not? What is the formula or rule to tell if something is a buffer or not? UBC Chem 123 Acid-Base Examples 20: Calculate the pH if 10.0 mL of 0.020 M benzoic acid is added to 40.0 mL of 0.004 M sodium benzoate. The pka of benzoic acid is 4.20. H₂O ² HA + benzoic acil - H₂ot +...
I just want to know how do you get the 10%, im using the formula (1 + i/n)^n - 1 but I'm not gettting this number. I used 5 years for n and 8% for i. Bonita Company sells 8% bonds having a maturity value of $2,290,000 for $2,116,380. The bonds are dated January 1, 2020, and mature January 1 2025. Interest is payable annually on January 1.

Please explain big O. I don't get it Prove the following, using either the definition of Big-O or a limit argument. (a) log_2 (n) elementof O(n/log_2(n)) (b) 2^n elementof O(n!) (c) log_2(n^2) + log_2 (100n^10) elementof O(log_2 (n)) (d) n^1/2 elementof O(n^2/3) (e) log(3n) elementof O(log(2n)) (f) 2^n elementof O(3^n/n^2)
I am having a difficult time remembering how to do this. I know the formula is C1V1=C2=V2 You need to prepare 21 mL of a 2.6 M solution of EDTA. No EDTA powder is available, but you do have 1 L of 13.8 M EDTA solution. Step by step, how would you prepare this solution? Things you may or may not need to know: • EDTA is heat stable. • EDTA is available to you only in liquid form (see...
Please show the work, I know you have to do the annuity formula first s=RX (x use factor table), then NPV formula, and then those 2 parts together and subtract cost of investment I think The annual profit from an investment is $25,000 each year for 5 years and the cost of investment is $75,000 with a salvage value of $40,000. The cost of capital at this risk level is 12%. Based on the given information, the net present value...
