Explain the indirect role of light reactions Vs Direct role of Calvin cycle reactions in sugar production
In a bromine-producing plant, explain how many liters of gaseous element albromine at 300 degree Celsius and 0.855atm are formed by the reaction of 275g of sodium bromide and 175.6 g of sodium bromate in aqueous acid solution. Presume no Br2 disso..
A student analyzed a 0.2078g sample containing aspirin using 0.1014M NaOH. The student obtained a % purity of 76.1%. Calculate the volume of NaOH that is required in order to reach the end point of the reaction. Molar mass for aspirin = 180.16g/m..
Explain while carbon is bonded to 4 hydrogen atoms to form CH4, the 2s and the three 2p orbitals undergo hybridization to form four sp3 orbitals. By hybridization of the carbon atom, a total of four lone electron orbital sites are established. The..
