Answer: The bonds that hold molecules together break apart and form new bonds.
Explanation:
A solution with a pH of 13.8 means that the solution is a strong base.
<h3>What is pH?</h3>
pH refers to power of hydrogen. The pH is a scale used to measure the degree of acidity or alkalinity of a solution.
pH scale ranges from 0 - 14
Where;
- 0 -6.9 indicates acidic
- 7.1 - 14 indicates basic
However, the closer the pH value is to 1, the more the acidity and vice versa while the closer it is to 14, the more the alkalinity and vice versa.
Therefore, a solution with a pH of 13.8 means that the solution is a strong base.

Answer: The "equation" here is vinegar + baking soda = carbon dioxide. The reactants are vinegar and baking soda. The products are carbon dioxide.
Explanation: The reactants are the "ingredients," or the two or more substances you mix in order to form the product, the ending result. In this situation, you mixed vinegar and baking soda, so those are the reactants. You ended up making CO2, the product.
Answer: A closed system, because energy can enter or leave the container, but the water molecules cannot
Explanation:
Open system: In this system energy and matter both have access to their surroundings beyond the boundaries of system. .
Closed system :In this type system only energy has an access to its surroundings beyond the boundaries of system but not matter.
Isolated system:In this type system exchange of both energy and matter are restricted to move outside the boundaries of system.
According to question, the system given is a closed system because energy is transferred from the burner to glass flask and from the glass flask to the water (matter). But water molecules are only getting condensed on the inside surface of the flask that is exchange of matter beyond the boundaries of the system is restricted. Hence, closed system ,A closed system, because energy can enter or leave the container, but the water molecules cannot.
