Answer: Option (d) is the correct answer.
Explanation:
A change that does not cause any difference in chemical composition of a substance are known as physical change.
For example, shape, size, mass, volume, density, etc of a substance are all physical changes.
And, a change that causes changes in chemical composition of a substance is known as chemical change.
For example, precipitation, reactivity, toxicity etc are chemical change.
Therefore, change in temperature, chemical precipitation of a solid
, production of a gas are all indications of a chemical change.
Thus, we can conclude that change in volume would not necessarily indicate a chemical reaction.
<h3>Pressure has additive properties meaning that if you add the partial pressures together, you obtain total pressure. P total = P1 + P2 + P3 + ... Pressure of container = pressure of H2 + Pressure of N2 + Pressure of F2 = 3atm + 2atm + 5atm = 10atm Hope that helped. ;)</h3>
The mixtures that can be separated using filtration are :
A. sand and water
C. Sugar and water
D. Salt and water
The size of pebbles is usually too big to be separated using filtration. It will get stuck in the process
