Answer:
d. each of the above (A, B, and C) occurs.
Explanation:
When an ionic species dissolves in water , the ionic compound dissociates into cation and anion , and the cation interacts with the negative end of the water molecules , and the anion interacts with the positive end of the water molecule .
During the process of dissolution , the interaction between , solvent - solute overcome the interaction between solute - solute molecules .
Hence , From the question , all the statement given are correct .
Answer:
B. Similar fossils were found in different continents.
Answer:
Explanation:
stoichiometry is used in cooking because it helps you determine the amount or proportion of compounds you will need in a chemical reaction. Stoichiometry is present in daily life, even in the cooking recipes we make at home. The reactions depend on the compounds involved and how much of each compound is needed to determine the product that will result.
The statement that best represents the law of conservation of matter with regard to chemical reactions would be the one that says the <u>reactants and products have the same number and type of atoms, but the atoms may be recombined.</u>
First, it is important to know that chemical reactions involve the breaking of bonds between atoms in reactants and the recombination of the atoms in products.
The law of conservation of matter also states that matter (atom) can neither be created nor destroyed in a reaction, but can be converted from one form to another.
Thus, going by the above points, the number of atoms of each element in reactants must also be the same in products. However, recombination of the atoms would most likely have occurred before reactions can take place.

The given reaction is C₅H₉O + O₂ → CO₂ + H₂O
On balancing the equation we get:
20 C₅H₉O + 90 O₂ → 100 CO₂ + 9 H₂O
This is a single replacement type of reaction. A single replacement reaction, also called a single-displacement reaction, refers to a kind of chemical reaction where an element reacts with a compound and occupies the place of another element in that compound.
