you close your eyes, does it almost feel like you’ve been here before? But if you close your eyes, does it almost feel like (volume increase) you've been here before? Oh, how am I gonna be an optimist about this? Oh, how am I gonna be an optimist about this? But if you close your eyes, ay oh, ay ay oh, ay oh, ay ay oh, ay ay oh, ay oh.” Then the song continues. See the riff? That is a taste of Bad Blood by Bastille. The album Bad Blood also reflects on Bastille in an interesting way. Bastille…
NH4 present) III. pH Test A) Add a little bit of unknown to a small amount of neutral water B) Fill several vials with test solution and use indicators to determine pH Common pHs for Anions and Cations: pH 1.5: HSO4- present; CO32-, HCO3-, OH- not present pH 2.5: SO42- present pH 3-3.5:…
increase in the number of hydroxyl (OH) groups in MCO after transesterification reaction [17]. Further, the results depicted in table 2 validates the above observation. Both the materials exhibited peak at 1734 cm-1 indicating the presence of the ester carbonyl group. Meanwhile, the band visualized at 1100 cm-1 in CO can be assigned to the secondary OH group. However, MCO revealed an absorption band at 1051 cm-1 which might be due to the introduction of primary OH groups (Scheme 2) after…
In the immunoassays (RIA, ELISA, and CPB) enzymatic, radioactive or electrochemilumnicent markers are used. This markers coupled with an antibody for the quantification of 25(OH) D, then an antibody identify the 25(OH) D. These techniques might be more or less fully automated, which make high-throughput…
of varying [OH-] on the rate of the reaction. To do this, you should complete the following table: Experiment [tBuCl]0 (M) [OH-]0 (M) Time (s) Reaction rate (M/s) Rate constant (s-1) 1 0.03 0.003 65 4.89 · 10-5 1.62 · 10-3 2 0.03 0.006 213 3.15 · 10-5 1.05 · 10-3 3 0.03 0.009 362 2.96 · 10-5 9.85 · 10-4 What is the dependence of [OH-] on the rate law? The effect of the increased or decreased [OH-] on the rate law is very minimal. As the concentration of OH- is…
yeah [Bridge] (It's fucking hot, hot) Winter in the city Somethin' 'bout this weather made these kids go crazy (It's hot) Even for February Somethin' 'bout this sun has made these kids get scary Oh, writin' in blood on my walls and shit Like, ah, oh my God Jumpin' off from the walls into the docks and shit Oh, ho ho ho, I'd be lyin' if I said I wasn't sick of it Baby (baby) come on (come on) come on (come on) [Chorus 3] I'm flyin' to the moon again, dreamin' about marzipan Taking all my…
NiCd is the chemical abbreviation for the composition of Nickel-Cadmium batteries, which are a type of secondary (rechargeable) batteries. Nickel-Cadmium batteries contain the chemicals Nickel (Ni) and Cadmium (Cd), in various forms and compositions. The nickel-cadmium battery, invented by Waldmar Jungner in 1899, offered several advantages over the then only rechargeable battery, lead acid, but the materials were expensive and the early use was restricted. Developments lagged until 1932 when…
We have a pitching substitution. Fernando Rodney replaces Trevor Cahill for the Cubs. Matt Carpenter is up to the plate. It’s called a strike! The Cubs fans here at Wrigley go crazy! He takes ball one. It’s a beautiful night for baseball. Oh, he takes ball two. Oh, a swing and a miss for strike two!! The fans here at Wrigley field are up on their feet cheering and going crazy, pushing Rodney to throw a third strike!! The fifth pitch goes foul. The Cubs fans are still going crazy. And he goes…
quantities were different. The very strong and sharp peak at 3704 cm-1 is identified as the O-H stretching which confirm the formation of Mg(OH)2. The Mg(OH)2 has a hexagonal crystal structure and easily undergoes basal cleavage, caused by formation of crack on the corrosion product layer [5,7-8]. It can be also observed that the absorbance of the spectra from the Mg(OH)2 was significantly lower in Mg-Zn-RE-0.5Ca alloy which led to lesser cracks compared to the other alloys. The broad adsorption…
