Why does BCl3 act as a Lewis acid? Solution : BCl3 is an electron deficient compounds since B atom has only six electrons in the valence shell. To complete its octet, it can accept an electron pair and hence acts as a Lewis acid. Why do BCl3 act as Lewis acid What is the change […]

What happens when butanol is oxidised? The alcohol is oxidised by loss of hydrogen. Oxidation and reduction in terms of hydrogen transfer is common in hydrocarbon chemistry. Butanol is oxidised by sodium dichromate (Na2Cr2O7) acidified in dilute sulphuric acid to form the aldehyde butanal. Butanal is oxidised to butanoic acid by adding an oxygen atom. […]

What is the mass of an ink pen? approximately 16 grams Does a triple beam balance measure mass? The triple beam balance is an instrument used to measure mass very precisely. Typically, the reading scale of the middle beam reads in 100 gram increments, the far beam in 10 gram increments, and the front beam […]

Is dissolving sugar in water a chemical change? Complete step-by-step answer: Physical changes and changes affecting the form of a chemical substance but not a chemical composition. Dissolving sugar in water is a physical change because sugar molecules are dispersed within the water but the individual sugar molecules are unchanged. Why is dissolving sugar into […]

Can limestone have fossils? Limestone is a sedimentary rock made almost entirely of fossils.
