Answer:
Physical weathering is caused by the effects of changing temperature on rocks, causing the rock to break apart. The process is sometimes assisted by water. Freeze-thaw occurs when water continually seeps into cracks, freezes and expands, eventually breaking the rock apart
Explanation:
The sulfur and nitrogen compounds in smog combine with water to form Acid Rain. Acid rain is harmful to the environment and infrastructure because of its aidic components.
Answer:
Adiabatic. This is a process where no heat is being added or removed from the system. Or can be simply stated as: no heat transfer (or heat flow) happening in a system.
Explanation:
Replacement reaction because one element takes place of another element in a compound.
Answer:
Student's percent yield = 94.6%
Explanation:
Given:
Estimated yield of BaSO₄(s) = 1.352 grams
Actual yield = 1.279 grams
Find:
Student's percent yield = ?
Computation:
Student's percent yield = [Actual yield / Estimated yield of BaSO₄(s)]100
Student's percent yield = ( 1.279 grams / 1.352 grams)100
Student's percent yield = (0.946)100
Student's percent yield = 94.6%
