Aluminium is a good conductor of heat
physical properties is what you can see about the element or object all other options are chemical properties
Answer:
The unknown amount of potassium chloride is 13.6 grams.
Explanation:
The reaction of 14 grams of KNO₃ with KCl produces a total mass of 27.6 grams of the products.
The law of conservation of mass tells us that the total mass of the reactants must be the same that the total mass of the products. So, we can find the mass of KCl as follows:

Where <em>r</em> is for reactants and <em>p </em>is for products



Therefore, the unknown amount of potassium chloride is 13.6 grams.
I hope it helps you!
<u>Answer:</u> The final volume will be 14.85 L.
<u>Explanation:</u>
To calculate the final volume when temperature increases, we use Charles' Law.
This law states that volume is directly proportional to the temperature of the gas if number of moles and pressure remains constant.

where,
= Initial volume and temperature
= Final volume and temperature
We are given:

Putting values in above equation, we get:


Hence, the final volume of the gas is 14.85L
I think it would be B maybe
