How much heat is needed to warm 250 g of water from 22 C to 98 C? The specific heat of water is 4.18 J/g . Be sure to include units but do not use scientific notation.
Use standard reduction potentials (shown below) to calculate the potential of a nickel-cadmium cell that uses a basic electrolyte that has a 0.6 M hydroxide concentration.
The majority of industrial method for the preparation of elemental phosphorus is heating a mixture of phosphate rock, carbon, and sand in electric furnace. The chemical reactions can be represented by 2Ca3(PO4)2 + 6SiO2 ? 6CaSiO3 + P4O10 and P4O10..
