"the same";
One mole of any given thing is 6 * 10²³ of it;
One mole of H₂O is 6 * 10²³ molecules;
One mole of O₂ is also 6 * 10²³ molecules;
Therefore for both substances, there are the same number of molecules.
Answer:
The maximum number of electrons present in a particular shell is calculated by the formula 2n^2. , where “n” represents the shell number. For instance, K shell is the first shell and it can hold up to 2(1)^2 = 2 electrons. Similarly, L shell is the second shell and it can hold up to 2(2)^2 = 8 electrons.

Answer:
A chemical change occurred, a gas and precipitate was produced
Explanation:
From the question , we are informed of science lab, where Cash mixes two clear liquids together in a beaker. Bubbles are produced, and a white solid forms and settles to the bottom.
In this case the change that took place is chemical change ( is one where new product are formed after two substance react) the bubbles that is produced signify the presence of gas in the product, white solid formed is reffered to as a precipitate( which is reffered to as solid that is been formed from a particular solution).
