Answer:
Starch is a viable indicator in the titration process because it turns deep dark blue when iodine is present in a solution. When starch is heated in water, decomposition occurs and beta-amylose is produced
<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
The element used in advertising signs is neon.
Elements are the building blocks of large molecules, and are made up by a certain configuration of protons, neutrons, and electrons, otherwise known as an atom. The answer is .C
Answer:
E. The number of moles of solute in both solutions is the same.
Explanation:
The dilution of a solution consist in increase the volume of solution decreasing, thus, the concentration of the solution. The moles of solute doesn't change in a dilution process.
Thus, when a solution is diluted, the relationship of the number of moles of solute in the more concentrated initial volume of solution to the number of moles of solute in the less concentrated final volume of solution is that:
E. The number of moles of solute in both solutions is the same. TRUE.
I hope it helps!
