Based on the scenario, that is not needed to calculate the mass of the calcium oxide is : D. the volume of the unknown mass
In order to find out the mass of a product, you just need the mass of the reactants and the mass of the product
hope this helps
The answer is 3. The releasing of energy means exothermic reaction. So the ΔH should be negative. And the greatest quantity of energy released means that the greatest number. So according to the table I, the answer is 3.
True I believe since every person has a different temperature and sound waves.
Ok I’m figuring this one out
Answer: chemical property.
Explanation:
The chemical properties are the capacity or incapacity of a substance to transform into one or more different substance either by reacting with one or more different substances or by decomposition.
Such properties can only be observed when such change (reaction) takes place and the substance, therefore, is transformed into one or more different substances.
On the other hand, the physicial properties can be observed or measured without changing the composition of the sample.
