Difference between melting point and melting range
Rudik [331]
The temperature at which a given solid will melt is called melting point.

The melting range is the span of temperature from the point at which the crystals first begin to liquefy to the point at which the entire sample is liquid.

Why are molecule atoms as far away from each other as possible
iVinArrow [24]

According to VSEPR theory, molecular geometry can be predicted by starting with the electron pair geometry about the central atom and adding atoms to some or all of the electron pairs.

For some jobs, “good enough” is good enough. That’s sometimes true in chemistry. More often, though, careful planning, calculati
insens350 [35]
When carrying out experiment in the laboratory to investigate physical changes, absolute measurement is usually not needed. For instance, one can just take a little sample of sodium chloride and dissolve it in water to demonstrate physical change. But for other experiments, such as the measurement of the catalase enzyme activity in a liver tissue. Careful measurements have to be made when preparing the chemicals that will be used in the experiment.

For an aqueous solution of sucrose (C12H22O11), determine: (a) the molarity of 3.30 L of a solution that contains 225.0 g of suc
dusya [7]

Answer:

a) Molarity = 0.199M

b) 21.6L of solution

c) 0.199 moles of sucrose in 1L

Explanation:

a) Molarity is the ratio of moles of solute (sucrose) in volume of solution (3.30L):

<em>Moles sucrose -Molar mass: 342,3g/mol-:</em>

225.0g * (1mol / 342,2965g) = 0.6573 moles

Molarity = 0.6573 moles / 3.30L

<h3>Molarity = 0.199M</h3><h3 />

b) 0.199M means 0.199 moles in 1L. 4.30 moles are in:

4.30 mol * (1L / 0.199mol) = 21.6L of solution

c) By definition, there are 0.199 moles of sucrose in 1L. This is the meaning of 0.199M
