This reaction supports the Law of Conservation of Mass (hint: is the equation balanced?):
enyata [817]

Answer:

False

Explanation:

<em>Left:</em>

K = 2 atoms

O = 1 atoms

H = 1 atoms

<em>Right: </em>

K = 2 atoms

O = 1 atoms

H = 2 atoms

O = 1 atoms

As you can see both sides do not have the same amount of atoms, therefore it is not balanced.

2 of 20 Which intermolecular force or bond is primarily responsible for the solubility of CH3OH in water? lonic bonding Hydrogen
Vlad [161]

Answer:

Hydrogen bonding

Explanation:

As a rule of thumb, "likes dissolve like", meaning polar solutes dissolve in polar solvents and nonpolar solutes in nonpolar solvents. In this case, water is polar (<em>dipolar moment</em> = 1.85 Debye) dissolves methanol which is also polar (<em>dipolar moment</em> = 1.69 Debye). Besides being dipoles, both molecules have atoms of Hydrogen with a covalent bond to more electronegative atoms of Oxygen. When this happens, stronger dipole-dipole interactions appear known as Hydrogen bonding. There is an electrostatic attraction between H (positive charge density) and O (negative charge density).

The molarity of a solution of 5.0 g of kcl in 100. ml of solution is ________.
sdas [7]
Molarity is defined as the number of moles of solute in 1 L of solution 
mass fo KCl in the solution is - 5.0 g
number of moles of KCl - 5.0 g/ 74.5 g/mol  = 0.067 mol
number of moles of KCl in 100 mL - 0.067 mol
therefore number of KCl moles in 1 L - 0.067 / 100 mL x 1000 mL = 0.67 M
molarity of KCl is 0.67 M
