None of the above, deoxyribonucleic acid is the full name of the abbreviation DNA
The states of matter change to produce the same or the new substance. When yeast is added to hydrogen peroxide bubble of carbon dioxide is formed which indicates chemical change.
<h3>What is a chemical change?</h3>
A chemical change is the formation of a new substance by the chemical alterations in the reactants. The yeast releases products of cellular respiration that react with hydrogen peroxide.
The reaction is exothermic as it releases heat and increases the temperature when measured by the thermometer. The Fizzing and bubbling occur when carbon dioxide reacts with H₂O₂ to produce a new substance.
Therefore, addition of yeast to hydrogen peroxide is a chemical change.

The answer is D, Magnesium.
For an anion or cation(negatively or positively charged ion) to replace a similarly-charged ion, it needs to be more active. This means that only a cation that is above Zinc on the reactivity scale can replace Zinc.
Since Aluminum was displaced in the reaction, that means the unknown metal is more reactive.
This means that our options are:
Lithium, Potassium, Calcium, Sodium, and Magnesium.
But because the metal did not displace the Sodium, it must be less reactive than it.
This gives us a new list of metals that are less-reactive than Sodium:
Magnesium, Aluminum, Zinc, Iron, Nickel, etc.
The only metal on both lists is Magnesium, and that means that your answer is D, Magnesium.
