Answer:
Yes. Burning usually observes this kind of law.
Explanation:
- The law of conversion of mass states that mass can never be formed nor can it be eradicated.
- This means that in case of burning, the amount of matter before and after will remain to be the same.
- It doesn't change at all.
- In conclusion, there's no form of change that can be able to affect matter.
- <u>Physical Properties :</u>
- It is a crystalline colorless solid structure it is soluble in solution such as ether, alcohol, and chloroform but insoluble in water.
- It is dangerous when it is dry and is very volatile and decomposes when it reaches 103 c.
2. <u>Chemical Properties :</u>
- It causes swelling of the skin and undergoes free radical products that are highly reactive.
- It is irritant when it contacts the skin it breaks down to yield oxygen and benzoic acid.
<u>Explanation:</u>
- Benzoyl Peroxide is widely used in industry at large scale.
- It is formed when there is a reaction between hydrogen peroxide and benzoyl chloride.
- Benzoyl peroxide is used in bread and cheese as the bleaching agent and also used in cosmetics as hair coloring.
- Because of its antibacterial property and a peroxide group it is applied to the human skin to treat acne.
<span>When naming compounds, the first thing you need to do is decide if the compound is ionic or molecular. *Ionic compounds
will contain both metals and non-metals, or at least one polyatomic
ion. *Acids will always include the (aq) symbol beside the formula, and
the name will include the word acid.</span>
During the experiment, scientists noted that several of the reaction beakers became hot to the touch. All of the following reactions could cause this result except endothermic and positive ∆H experiments.
<u>Explanation:</u>
If the beakers are becoming hot during experimentation, then that means the energy is being released from the reactants during this experiment. As the energy is being released that enthalpy change will also be negative as the enthalpy change is calculated as the difference of enthalpy of reactants from products.
So in these cases, heat is released making the beakers hot. So for the exceptional case, the experiment should be endothermic in nature and positive enthalpy change should be there in the experiment. Such that the heat will not be released leading to no heating of beakers.
