Answer:
Explanation:
Hello,
At first, it turns out convenient to compute the total moles of sodium that will be dissolved into the solution by considering the added amounts of sodium bromide and sodium sulfate:
Once we've got the moles we compute the final volume via:
Thus, the molarity of the sodium atoms turn out into:
Now, we perform the same procedure but now for the bromide ions:
Finally, its molarity results:
Best regards.
<em>Answer:</em>
<em>An Atom can turn into both solid and liquid form depending on the temperature of its surroundings </em>
<em>Explanation:</em>
<em>Scientists have discovered a new state of physical matter in which atoms can exist as both solid and liquid simultaneously.
Researchers have found, however, that some elements can, when subjected to extreme conditions, take on the properties of both solid and liquid states.</em>
The experiment is related to the demonstration using Pepper. When pepper is spread over water, it clumps together This is because pepper is hydrophobic. When repeated with sugar and salt, they instantly dissolved. This means they are attracted to water. When also sprinkled on the surface of the water, it floats. This is caused by surface tension.
To break the surface tension of water, one can use aeration or the use of chemicals such as soap molecules which contain a long chain of hydrogen as well as carbon atoms.
<h3>What is surface tension?</h3>
Surface tension is the propensity of liquid surfaces at rest to shrink to the smallest feasible surface area. Surface tension permits items with a higher density than water, such as razor blades and insects (such as water striders), to float on the water's surface without being immersed.
A force tensiometer can be used to measure surface tension. The forces exerted on a probe situated at the liquid-gas or liquid-liquid interface are measured by these devices.
