Analytical chemistry -- A task that would fall into this area of chemistry is measuring the level of lead in drinking water.
Answer : -4.65 °C
Explanation : On solving the sum w.r.t to water as the aqueous solvent in solution;
(101.28°C - 100°C) / (0.512 c/m) = 2.5 m,
Now, 2.5 m X (1.86 °C/m) = 4.65 °C which will be the change in temperature of the solution in °C;
To find the freezing point we have to get it subtracted by 0°C
0°C - 4.65°C = -4.65°C
Cl because it gains electron and become negatively charged
Answer:
b
Explanation:
orbital overlap electron densities.
Historically, the first chemical definition of an acid and a base was put forward by Svante Arrhenius, a Swedish chemist, in 1884. An Arrhenius acid is a compound that increases the H+ion concentration in aqueous solution. The H+ ion is just a bare proton, and it is rather clear that bare protons are not floating around in an aqueous solution. Instead, chemistry has defined the hydronium ion(H3O+) as the actual chemical species that represents an H+ion. H+ ions and H3O+ ions are often considered interchangeable when writing chemical equations (although a properly balanced chemical equation should also include the additional H2O). Classic Arrhenius acids can be considered ionic compounds in which H+ is the cation. Table 12.1 "Some Arrhenius Acids"lists some Arrhenius acids and their names.
