SUMMARY: Write a 3-4 sentence summary about the Periodic Table.
denis23 [38]

Answer:

The periodic table, also known as the periodic table of elements, is a tabular display of the chemical elements, which are arranged by atomic number, electron setup, and repeating chemical properties. The structure of the table shows occasional (popular things/general ways things are going). The seven rows of the table, called periods, generally have metals on the left and nonmetals on the right. The columns, called groups, contain elements with almost the same chemical behaviours. Six groups have accepted names as well as assigned numbers: for example, group 17 elements are the halogens; and group 18 are the noble gases. Also displayed are four simple rectangular areas or blocks connected with the filling of different atomic orbitals.

Why does increasing the temperature make a solid dissolve faster?
Deffense [45]

Answer:

The chemical bonds of the solid are broken faster.

Explanation:

As the temperature of a solution is increased, the average kinetic energy of the molecules that make up the solution also increases. The increased vibration (kinetic energy) of the solute molecules causes them to be less able to hold together, and thus they dissolve more readily.

Hey can someone help me and show work please
Ivahew [28]

Answer: 2.54g

Explanation:

Molar Mass of H2O2 = (2x1) + (2x16) = 34g/mol

1mole (34g) of H2O2 contains 6.02x10^23 molecules

Therefore Xg of H2O2 will contain 4.5x10^22 molecules i.e

Xg of H2O2 = (34x4.5x10^22)/6.02x10^23 = 2.54g
