Answer:
The correct option is: a. Photosphere
Explanation:
Sun is the brightest star in the sky of our planet Earth and the principle component of the Solar System. It is a <u>gaseous object</u> that is made up of hot plasma and contributes 99.86% to the total mass of our Solar System.
<u>The Sun does not have a clearly defined surface.</u> The <u>visible surface of the Sun is known as the Photosphere</u>, which is the deepest visible portion of the Sun.
Answer:
C. 2.4 M
Explanation:
Because you started with 12M solution of KCl, that means that there was a concentration of 12 mols of KCl per Liter of solution. (12mol/1L =12 M). Since there was only 0.5L of solution, there was only 6 mols of KCl because there is only 12 mols per 1 Liter, so half of that volume would have half the amount of solute to keep that true. (6mol/.5L = 12 M). With the new water added, the formula becomes (6mols KCl/ 2.5L of water =2.4 M)
Answer:
A chemical change occurred, so even if Cash heats it, the white solid will remain.
Explanation:
- A physical change occurred, so if Cash heats it, the white solid will dissolve to form the original mixture of clear liquids.
- A physical change occurred, so even if Cash heats it, the white solid will remain.
- A chemical change occurred, so if Cash heats it, the white solid will dissolve to form the original mixture of clear liquids.
- A chemical change occurred, so even if Cash heats it, the white solid will remain.
<em>The correct answer would be that a chemical change occurred, so even if Cash heats it, the white solid will remain.</em>
Chemical changes occur when atoms in a substance or mixture of substances are rearranged, leading to the formation of new substances.
<u>In this case, the mixture of the two clear liquids led to the formation of gas in form of bubbles and a white solid forms that settle at the bottom. The formation of these 2 substances from the mixture of the two clear liquid is an indication of chemical reaction/changes. Hence, even if cash heats the resulting mixture, the white solids will likely remain.</u>
