g When water and perchloric acid (HClO4) are mixed, heat is released. The resulting solution is not an ideal solution, in terms of Raoult’s Law. How should the boiling point and the vapor pressure of a solution of HClO4 in H2O differ from what is expected for an ideal solution? A) boiling point higher than expected, vapor pressure lower than expected B) boiling point higher than expected, vapor pressure higher than expected C) boiling point lower than expected, vapor pressure lower than expected D) boiling point lower than expected, vapor pressure higher than expected E) boiling point and vapor pressure are both the same as expected for an ideal solution

A) boiling point higher than expected vapor pressure lower than expected.

Explanation:

When water is introduced with heat it vaporize at a temperature of 100 degree centigrade. When hydrochloric acid is added to the water its boiling point of water increases slightly. The difference in the boiling point is due to the presence of heavier molecules in acid.

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
