WebApr 12, 2024 · Synthesis of Annular Fe 3 O 4 19. Annular Fe 3 O 4 was prepared by hydrothermal method. Briefly, 0.02 M of FeCl 3 ·6H 2 O, \(1.8 \times 10^{ - 4}\) M of NaH 2 PO 4 ·2H 2 O and \(5.5 \times 10^{ - 4}\) M of Na 2 SO 4 were dissolved in 1000 mL of deionized water and stirred evenly on a magnetic stirrers. The stirred homogeneous … WebGiven f (x) = x2 + 2x − 1, evaluate f (§). Well, evaluating a function means plugging whatever they gave me in for the argument in the formula. This means that I have to plug this character " § " in for every instance of x. Here goes: f (§) = (§) 2 + 2 (§) − 1. = § 2 + 2§ − 1. This is definitely weird-looking, but it follows all ...

WebSection 4.8 Analyzing Graphs of Polynomial Functions 215 Identifying Even and Odd Functions Determine whether each function is even, odd, or neither. a. f(x) = x3 − 7x b. g(x) = x4 + x2 − 1 c. h(x) = x3 + 2 SOLUTION a. Replace x with −x in the equation for f, and then simplify. f(−x) = (−x)3 − 7(−x) = −x3 + 7x = −(x3 − 7x) = −f(x) Because f(−x) = −f(x), the … Webtwo C−H ⇒ 413 x 2 = +826 kJ two H−H ⇒ 432 x 2 = +864 kJ The sum is +2529 kJ. Note there are two C−H bonds in one molecule of C 2 H 2 and there is one H−H bond in each of two H 2 molecules. Two different types of reasons for multiplying by two. 2) You get energy out when a bond (any bond) forms. Bond making is exothermic.
