Don’t you just hate it when ATMs charge you to take out your own money? It really grinds my gears, man. Really raises up that arterial tension, man. A $2 fee at a different bank than yours is a pain. Having to pay $4 at a concert to put your mitts on one of your […]
It’s pretty hard to become immortal. Apparently JonTron did it by eating a magical gyro, but it turns out that it must have been a unique gyro. Other gyros don’t work, apparently – the knowing look of pity I got from the guy at the Greek food truck when I asked for the “Immortality Special” […]
If you live in a dorm, I can probably guess exactly what you see when you look up: a big, boring industrial overhead light. That’s just what most dorms come with. They’re cheap, they light the room sufficiently, and that’s about it. The certainly won’t win any points for looks. When I moved into my first […]
What type of bond exists between the two carbon atoms? A carbon–carbon bond is a covalent bond between two carbon atoms. The most common form is the single bond: a bond composed of two electrons, one from each of the two atoms. The carbon–carbon single bond is a sigma bond and is formed between one […]
How many milliseconds MS are there in 3.5 seconds? 3500 miliseconds Which of these time measurements is the smallest? What is a zeptosecond? A zeptosecond is a trillionth of a billionth of a second. That’s a decimal point followed by 20 zeroes and a 1, and it looks like this: 0.001. The only unit of […]
Is myoglobin positive or negative? Normally, the iron group in myoglobin has an oxidation state of 2+. However, when oxygen binds to the iron, it gets oxidized to an oxidation state of 3+. This allows the oxygen that is binded to have a negative charge, which stabilizes it. Why can’t myoglobin serve as an oxygen […]
How can you tell with chemical formulas whether it is an element compound or a mixture? If it is pure, the substance is either an element or a compound. If a substance can be separated into its elements, it is a compound. If a substance is not chemically pure, it is either a heterogeneous mixture […]
What is the process at a water treatment plant? Coagulation and flocculation are often the first steps in water treatment. Chemicals with a positive charge are added to the water. During sedimentation, floc settles to the bottom of the water supply, due to its weight. This settling process is called sedimentation. How do waste water […]
Which salts will be more soluble in an acidic solution? For CuBr adding H+ forms HBr and that is a weak acid; therefore, CuBr is more soluble in acid than in water. For Ag2SO4 adding H+ forms HSO4- and that is k2 for H2SO4, there is no k1 since H2SO4 is a strong acid for […]
What are temperature scales explain how Celsius and Fahrenheit scales are defined? Temperature is a measure of the average kinetic energy of the particles in matter. The Fahrenheit scale defines the freezing point of water as 32°F and the boiling point as 212°F. The Celsius scale sets the freezing point and boiling point of water […]
