2. Why was it important to examine both the color and the streak of your minerals? Think about streak and explain why it’s calle

Delicious77 [7]

It is important to examine both the colour and the streak of a mineral because the streak may be completely different from the colour of the hand specimen.
The streak of a mineral is the color it possesses after it has been grounded to a fine powder. The streak test has to be done on minerals because it is a more reliable way of identifying a mineral with its color.<span />

Calcium chloride is added to the roadways after a snowstorm. Which colligative property is being showcased here?

vlabodo [156]

Answer:

Option (D) freezing point depression

Explanation:

Calcium chloride is added to the roadways after a snowstorm because it reduces the freezing point of the ice. Further more, it has been observed that the calcium chloride also produces enough heat which enhances the melting of the ice as it produces an exothermic reaction.

A bacteria culture begins with 15 bacteria which double in amount at the end of every hour. Solve for the number of bacteria tha

pshichka [43]

The number of bacteria is given by:
N(t) = N(o) x 2ⁿ
Where N(t) is the number after n hours have passed and N(o) is the original number which is 15.
The number grown in the 12th hour is the difference in the number after the 11th and the 12th hour. Thus:
15 x 2¹² - 15 x 2¹¹
= 30,720 bacteria
