A 50g sample of an unknown metal is heated to90C it is placed in a perfectly insulated container along with 100g of water at a initial temp of 20C the temperature of both metal & water become equal at 25C the specific heat of water is 4.18J/g C what is the specific heat capacity of the metal

Nitrogen dioxide reacts with water to form nitric acid and nitrogen monoxide according to the equation: 3no2(g)+h2o(l)→2hno3(l)+no(g) part a suppose that 4.2 mol no2 and 0.50 mol h2o combine and react completely. which reactant is in excess? express your answer as a chemical formula. nothing

Which of the following elements would you expect to have the lowest ionization energy value? fluorine, lithium, neon, nitrogen
