Answer:Why does weathering cause erosion
Explanation:Organic weathering happens when plants break up rocks with their growing roots or plant acids help dissolve rock. Once the rock has been weakened and broken up by weathering it is ready for erosion. Erosion happens when rocks and sediments are picked up and moved to another place by ice, water, wind or gravity.
Answer: 0.113 moles of NaCl are created as a result of decomposing 12 grams of 
.
Explanation:
To calculate the moles :
The balanced chemical equation for decomposition of is:
According to stoichiometry :
2 moles of give = 2 moles of 
Thus 0.113 moles of give =
of
Thus 0.113 moles of NaCl are created as a result of decomposing 12 grams of .
a ceramic or metal container in which metals or other substances may be melted or subjected to very high temperatures.
"the crucible tipped and the mold filled with liquid metal"
a situation of severe trial, or in which different elements interact, leading to the creation of something new.
"their relationship was forged in the crucible of war"
Test tubes, spot and/or well plate will be used to combine substances in bottles and form a reaction is referred to a true statement.
<h3>What is a Chemical reaction?</h3>
This is the reaction which involves substances known as reactants combining new substances which are referred to as products. This is usually done in the laboratory and equipment and tools such as test tubes, thermometer etc are used.
Test tubes, spot and/or well plate are often used to combine substances in bottles and form a reaction which must be handled with care to ensure it doesn't spill.
This is therefore the reason why the option true was chosen as the most appropriate choice.
