In an experiment, 2.75 g of NH3 are allowed to react with 3.64 g of O2: NH3 + O2 -> NO +H20
a. Balance the equation.
b. Which reactant is the limiting reagent?
c. How many grams of NO are formed?
d. How much of the excess reactant remains after the reaction?

It is a mixture. simply put, a compound must be pure, that is, of only one chemical structure and composition. a mixture is made of different chemical substances (i.e. elements, molecules, compounds) that are not chemically bonded to each other, but instead physically grouped together, as in the case of gasoline (a homogeneous solution).

The se-ci  bonds is more polar  than s-br bond

Those are different gas lawshere is a brief description of themcharles's law states that volume and temperature are directly proportional to each other as long as pressure is held constant.  boyle's law asserts that pressure and volume are inversely proportional to each other at fixed temperature.gay-lussac's law introduces a direct proportionality between temperature and pressure as long as it is at a constant volume.    source:
