The answer is C. <span>The density of the fluid is greater than the density of the object.</span>
Keep in mind that atomic number is the number of protons in the atom of the element. Therefore, in the case where there are 78 protons, we can conclude that the atomic number of this element is ALSO 78.
Let me know if you need anything else.

The answer is D. Rubber. Because A, B, and C are metal materials that will insulate heat without any gaps. Hope this helped!
It would be the molecule that can contain <span>How many formula units are in 0.25 mile of Na2o</span>the ester functinal
Options:
A reverse phase TLC plate because the nonpolar stationary phase will interact with polar compounds more strongly.
A normal phase TLC plate because the polar stationary phase will interact with polar compounds more strongly.
A reverse phase TLC plate because the polar stationary phase will interact with polar compounds more strongly.
A normal phase TLC plate because the nonpolar stationary phase will interact with nonpolar compounds more strongly.
Answer:A normal phase TLC plate because the polar stationary phase will interact with polar compounds more strongly.
Explanation:TLC(THIN LAYER CHROMATOGRAPHY) is a solid (stationary phase) and a liquid(mobile phase) technique of separation and purity determination that uses the principle of that different compounds have different adsorption rate and different solubility rate to the two phases between which they are partitioned.
ON A DEVELOPED THIN LAYER CHROMATOGRAPHIC PLATE A PURE COMPOUND WILL APPEAR ONLY ON ONE SPOT.
With TLC one can analyse multiple samples at the same time.
