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. […]

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 […]

Can Atom survive without electron?
Can Atom survive without electron? Electrically neutral atoms can exist with no electrons. So an atom can’t have no electrons as it, by definition has protons and to be neutral must have electrons. You can have an ion, such as a hydrogen ion (you might call it a proton). What would happen if an atom […]
What is the minimum velocity needed to transport a cobble?
What is the minimum velocity needed to transport a cobble? At 10 cm per second [?] is eroded whilst would be deposited. Cobbles are upwards of 170cm per second. Deposition starts to occur at cm per second for particles of approximately 0.01mm in size. Boulders require the smallest velocity for deposition, at only cm per […]
