Answer:
Baking Soda is NaHCO3 ---Sodium hydrogen Carbonate
Excessive use of Fertilizer can cause plants to develop shallow root systems,Decrease soil fertility and reduce Quality of Crops.
Both theories and laws could potentially be falsified by countervailing evidence. Theories and laws are also distinct from hypotheses. Unlike hypotheses, theories and laws may be simply referred to as scientific fact.
Answer:
D.) decomposition
Explanation:
A.) is incorrect. In double-displacement reactions, the cation of one compound is swapped with the cation of another.
These reactions have the general structure: AB + CD -----> AD + BC.
B.) is incorrect. In single-displacement reactions, the an element within a compound is swapped with another element.
These reactions have the general structure: AB + C -----> AC + B.
C.) is incorrect. In synthesis reactions, two or more elements/compounds are combined to create a new and larger compound/molecule.
These reactions have the general structure: A + B -----> AB.
D.) is correct. In decomposition reactions, a compound/molecule is broken down into smaller elements/compounds. In the given reaction, water (H₂O) separates into its respective elements, hydrogen (H₂) and oxygen (O₂).
These reactions have the general structure: AB -----> A + B
The molarity of H2SO4 is the number of moles in 1 L of solution.
The molarity is 2.0 mol/L
This means that there should be 2 moles in a 1 L solution to make up this molarity.
In this case we need to make up a 5 L solutions with that molarity. Then the amount of moles required are - 2 mol/L x 5 L = 10 mol
