Answer:

The polarity of a magnet usually means the direction of a vector which points from the south pole of the magnet toward the north pole. ... In this case the polarity is expressed in a way that indicates a circular direction, such as clockwise, or as a perpendicular vector representing the curl of the internal field.

In a permanent magnet, a magnetic field is produced by the composite motions of electrons in geometrically aligned atoms.

A magnetic field is characterized by poles called north and south. Magnetic polarity refers to the orientation of these poles in space.

Is the water of hydration covalently bound to the compound?

WINSTONCH [101]

The water of hydration is not covalently bound to the compound.

Many compounds, especially ionic compounds contain molecules of water of hydration which appears as part of the chemical formula of the compound.

This water of hydration is only attached to the crystal of the compound loosely. There is no chemical interaction between the water molecules and the crystal of the compound.

To prove this, the water of hydration is easily driven off by heating. It wouldn't have been possible to drive it off by heating if was covalently bonded to the compound.

Therefore, the water of hydration is not covalently bound to the compound.

A student prepares a solution by dissolving 60.00 g of glucose (molar mass 180.2 g mol-1) in enough distilled water to make 250.

anyanavicka [17]

Answer:

1.332 Molar is the molarity of the glucose solution.

Explanation:

Molarity of the solution is the moles of compound in 1 Liter solutions.

$Molarity=\frac{\text{Mass of compound}}{\text{Molar mas of compound}\times Volume (L)}$

Mass of glucose = 60.00 g

Molar mass of glucose = 180.2 g/mol

Volume of the solution = V = 250.0 mL = 0.250 L

(1 mL = 0.001 L)

$Molarity=\frac{60.00 g}{180.2 g/mol\times 0.250 L}=1.332 mol/L$

1.332 Molar is the molarity of the glucose solution.
