I can't actually answer this one if the empirical formula is not given. Luckily, I've found a similar problem from another website. The problem is shown in the picture attached. It shows that the empirical formula is CH₂O. Let's calculate the molar mass of the empirical formula.
Molar mass of E.F = 12 + 2(1) + 16 = 30 g/mol
Then, let's divide this to the molar mass of the molecular formula.
Molar mass of M.F/Molar mass of E.F = 180/30 = 6
Therefore, let's multiply 6 to each subscript in the empirical formula to determine the actual molecular formula.
<em>Actual molecular formula = C₆H₁₂O₆</em>
Answer:
Option (D)
Explanation:
Weathering is usually defined as the disintegration of rocks at the surface of the earth. This break down of rocks is mainly caused by the geological processes that occur on the earth's surface. This process results in the formation of sediments that are transported and deposited in a new environment.
This weathering process primarily takes place in three different ways such as-
- Physical weathering- Here, the rocks are broken down by the physical agents such as wind, water, ice.
- Chemical weathering- Here the rocks are broken down when interacts with the chemical containing water.
- Biological weathering- here, the rocks are broken down due to the activities done by organisms such as plants and animals.
In the given condition, Quincy can see a real example of rock weathering in the high mountainous region, as in the mountainous region the rocks are frequently weathered and eroded by the agents such as wind, water, and ice.
Thus, the correct answer is option (D).

Incomplete question. The remaining part reads;
Choose the correct words or phrases to complete the sentences.
Global winds occur due to
<u>1. Choose...</u>
a. solar currents
b. convection currents
c. sea breezes
d. uneven heating
over a large area and this forms
2. Choose...
a. solar currents
b. convection currents
c. sea breezes
d. uneven heating
caused by cool and warm air.
Answer:
<u>1. d. uneven heating</u>
<u>2. b. convection currents</u>
Explanation:
1. What Beto should know is that as the earth moves and rotates around the sun, some parts of the Earth receive more sunlight and others less, which then leads to uneven heating over a large area of the earth.
2. This uneven heat then forms a convection current containing varying patterns of air spreading to various parts of the globe.
