4. The manufacturers of the aspartame-containing sweetener claim that one packet of their sweetener provides the same
sweetness as two packets of table sugar (sucrose). The mass of two packets of table sugar is roughly 6 times greater than the
mass of one packet of the sweetener. (In other words, 1 g of sweetener has the same sweetness as 6 grams of sucrose.)
Based on this information and your experimental results (mg Aspartame / g Sweetner = 78.65), determine how many times
sweeter aspartame is than sucrose (find the grams of sucrose that has the same sweetness as 1 g of aspartame).

5. a) At what temperature is the temperature in degrees Fahrenheit equal to
twice the temperature in degrees Celsius?
b) The average daytime temperatures on earth and Jupiter are 72 °F and
313 K, respectively. Calculate the difference in temperature, in C.
between these two planets.
6. For a material to float on the surface of the water, the material must
have a density less than that of water (1.0 g/mL) and must not react with
the water or dissolve in it. A spherical ball has a radius of 0.50 cm and
weighs 2.0 g. Will this ball float or sink when placed in water? (Note:
Volume of a sphere r .)
7. a)Using examples, explain the difference between a physical property and
a chemical property. b) Do the following statements describe chemical or
physical properties?
(i) Oxygen gas supports combustion. (ii) Fertilizers help to increase
agricultural production. ii) Water boils below 100°C on top of a
mountain. (iv) Lead is denser than aluminum. (v) Uranium…

Distinguishing a metal from a nonmetal by physical properties
In the table below, there are descriptions of an experiment on samples of three different chemical elements. Decide whether the element is a metal or
nonmetal, if you can. If there is not enough information to decide, choose can't decide in the third column.

Element 2 is a hard silvery-grăy solid. Wires are fastened to each side of
a 2 cm slab of it, and an ordinary household 9 V battery is hooked up so
that it can feed electricity through the slab to an LED. The LED glows
