Mixture

Explanation:

Definition:

              An impure substance that contain two or more pure substances that retains their individual chemical characteristics.

Examples:

1.  Smoke and fog(smog)

2.  Dirt and water(mud)

3.  Sand , water and gravel(cement)

4.  Water and salt (sea water)

5.  Petroleum, hydrocarbons and fuel addictives(Gasoline)

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.

answer: a tank of height h is filled with water and sits on the ground. water squirts from a hole at a height y above the ground and has a range r. for two y values, 0 and h, r is zero. determine the value of y for which the range will be a maximum.
