What is the charge of SO3? Answer. The Oxidation states in SO3(g) are: Sulfur (+6) & Oxygen (-2), because SO3(g) has no charge. However in (SO3)2 – (aq) the Oxidation states are: Sulfur (+4) & Oxygen (-2). Don’t get the two confused, they may both be written without the charge, but if SO3 is (aq) […]

Why the resistance of an ideal ammeter is zero? An ideal ammeter would have zero resistance so that there was no voltage drop across it, and so it would not affect a circuit into which it was placed. A zero resistance will not change the resistance of a circuit is placed in series and hence […]

At what temperature does sugar caramelize? 320°F Does caramelized sugar have less calories? Not only does toasted sugar taste less sweet, it has less sucrose, fewer calories, and a lower glycemic index than plain sugar. Is caramelized sugar still sugar? What is caramel? Caramel is simply sugar that has been cooked until it browns. Granulated […]

Why do full moons make me feel weird? A new study found that humans get less sleep and less deep sleep during a full moon. Swiss researchers found that even in rooms in which the moon and outside environment cannot be sensed, the same holds true. What does a wolf moon mean? The January full […]

What are the four exceptions to Mendelian rules? These include: Multiple alleles. Mendel studied just two alleles of his pea genes, but real populations often have multiple alleles of a given gene. Incomplete dominance. Codominance. Pleiotropy. Lethal alleles. Sex linkage. What are the 3 principles of heredity? The three principles of heredity are dominance, segregation, […]

What is Schrodinger equation for free particle? The wave function Ψ(x, t) = Aei(kx−ωt) represents a valid solution to the Schrödinger equation. The wave function is referred to as the free wave function as it represents a particle experiencing zero net force (constant V ). Can a free particle be Normalised? Yes you can normalize […]

How much is true weight if scale shows 100kg? The correct unit for force is the Newton (=1 kg·m/s2) which is abbreviated N. So a 100 kg mass really weighs about 980 Newtons on Earth. What is the most accurate body weight scale? 1. Most accurate scale. The sleek RENPHO Bluetooth Body Fat Scale syncs […]

What 2 things determine the power force of a kick? The basic tenants of kicking performance involve angular velocity of the hip generated through a stretch-shortening cycle (SSC) and the linear velocity of the foot in combi- nation with the force applied to the ball, which determines kicking power (Figure 1). Why can kickers kick […]

Why does not a running bicycle fall? The answer is that you slip and fall and no gyroscopic force of the wheels or anything else prevents this. The answer is that if you try to turn (lean) even a little bit too much the sand flows under the bike wheel and doesn’t provide enough friction […]

Can you hit a piece of tissue in mid air? Why can’t he hit a piece of tissue paper in midair with the same amount of force? The boxer can only hit the tissue paper with a force as large as the tissue paper can exert on the boxer, and the low-mass tissue can only […]
