A gas occupies 672 mL at 785 mmHg. What volume would it occupy at 453 mmHg at constant temp??
What scientific principle or law is used in the process of balancing chemical equations. Define the terms limiting reactant and excess reactant.
Reaction of NO with chlorine to yield NOCl is pseudo-first order if NO is present in a large excess. Determine the rate constant of this reaction i
By what factor (The factor is the ratio of the rates) does the rate of this isomerization reaction increase as the temperature increases from 256 degree celsius to 297 degree celsius ?
the rate constant for the second order -reaction is NOBr(g)------>NO(g)+1/2Br2(g) is 48 L/mol*min at a certian temperture. How long will it take for 90.0% of a .0200M solution of NOBr to decompose
Metals such as magnesium and zinc react with dilute sulfuric acid to give hydrogen, according to the equation: M (s) + H2SO4 (aq) -------> MSO4 (aq) + H2 (g) When 5.00 g of a mixture of powdered magnesium and zinc were dissolved in diluted sulfuri..
