Since you're only asking for the last 3 items, here are the answers:
3. Maine is located in the northern hemisphere. If there is a high pressure, the wind is blowing clockwise. If there is a low pressure, the wind direction will be in the opposite direction.
4. Colorado is in the northern hemisphere. If there is a low pressure, the wind is going counterclockwise. If there is a high pressure, the opposite is true.
5. There is no map so I can't give you the exact answers.
1.65g MgO = 1g Mg
1.65 - 1 = 0.65 g of O in MgO
solve it using proportion:
1g Mg / 0.65g O = x (g) Mg / 16g O
or 1 / 0.65 = x / 16
24.6 g is the answer.
if 1 gram of oxygen requires 1.65 grams of Mg
then 16 grams of oxygen will require 16 ( 1.65) or 26.4 grams.
.07! you divide 7 by 100%
Answer: By performing the flame test
Explanation:
The flame test can be performed by the teacher to visually identify the substance in the solution. The metals give a characteristic color on burning. The heat of the flame causes the excitation of the electrons present in the metal ions this leads to release of energy along with the emission of visible wavelength of light. This visible light can be observed by human eye. For example, the copper produces the blue color in flame, barium gives green flame, and sodium gives yellow flame.
