Answer:
Explanation:
7) A block of wood
has a length of 10.2
cm, a width of 6 cm
and a height of 4.1
cm. The wood has
a total mass of 179
grams. What is the
volume of the
wood and what is
the density of the
wood?
volume = L XW XH=10.2 X 6 X4.1 =250.92cm^3
DENSITY = M/V = 179gm/250.92 cm^3
=0.713 gm/cm^3
Answer:
The answer is C. The high solvation energy for LI+
Explanation:
LiF has lower solubility because of the high solvation energy of Li+ ion. This is due to the smaller size and very big charge compared to Cs+ ion which has a bigger size and solvent molecules easily surround it.
Solvation energy is simply the amount energy that is required to make a solute dissolve in a solvent.
Answer: Because sulfur is directly below oxygen in the periodic table, these elements have similar electron configurations. As a result, sulfur forms many compounds that are analogs of oxygen compounds, as shown in the table below. ... O=O. double bonds are much stronger than S=S double bonds.
Answer:
Krypton has 4 orbital shells
<u>Extra Information:</u>
<em>Krypton has 36 electrons which are arranged in these 4 orbit shells, </em>
<em>The order in which electrons are arranged in these shells is 2,8,18,8</em>
