Does oxygen have a triple bond? Oxygen tends not to form triple bonds due to formal charge reasons. If oxygen starts with 6 electrons and forms a triple bond, then it has 2 lone pair electrons. Using the formal charge formula, 6 – (2+6/2) = 1. Since oxygen is so electronegative, it’ll tend not to […]
What are the possible sources of error in titration?
What are the possible sources of error in titration? Several factors can cause errors in titration findings, including misreading volumes, mistaken concentration values or faulty technique. Care must be taken as the solution of the known concentration is introduced into a specific volume of the unknown through laboratory glassware such as a burette or pipette. […]

Multiple sclerosis is an autoimmune disease that directly affects a certain part of the neuron. The disease causes a nerve signals to slow down, leading to problems […]
What is the formation of the planets?
What is the formation of the planets? According to our current knowledge, planets are formed around a new star by condensing in a disc of molecular gas and dust, embedded within a larger molecular cloud. Condensation increases until they become giant planets, which are heated, then cleanse their orbits in the disc and possibly bend […]
How do you solve an equation with two variables?
How do you solve an equation with two variables? In a two-variable problem rewrite the equations so that when the equations are added, one of the variables is eliminated, and then solve for the remaining variable. Step 1: Multiply equation (1) by -5 and add it to equation (2) to form equation (3) with just […]
What is Ammeter explain with diagram?
What is Ammeter explain with diagram? An ammeter (from ampere meter) is a measuring instrument used to measure the current in a circuit. Electric currents are measured in amperes (A), hence the name. Instruments used to measure smaller currents, in the milliampere or microampere range, are designated as milliammeters or microammeters. What is meant by […]
Is oil and vinegar a heterogeneous mixture?
Is oil and vinegar a heterogeneous mixture? When oil and vinegar are mixed, they form a heterogeneous mixture with two layers, or phases. The oil phase floats on the water, or vinegar, phase. A heterogeneous mixture consists of two or more phases. At the beach, you realize that both ocean water and sand are mixtures. […]
What are the disadvantages of mercury?
What are the disadvantages of mercury? The Weaknesses or the disadvantages of Mercury: It cannot measure very low temperature, because its freezing point is high (-40ºC) Mercury is poisonous, so it harmful if its tube is broken. Its price is very high. display is harder to read. cannot be used for thermograph. slow response. fragile. […]
