Answer:

<h3>\huge{ \underline{ \underline { \bold{ \sf{ \orange{See \: below}}}}}}</h3>

Explanation:

▪️\underline{ \bold{ \sf{ \blue{Chemical \: reaction}}}}

⇒The composition , decomposition or displacement of molecules of matter during chemical change is called chemical reaction.

▪️\underline{ \bold{ \sf{ \purple{ \: Further \: more \: explanation}}}}

Various conditions bring about these changes. The chemical reactions are represented by chemicalequation. The compounds or elements that take part in chemical reaction are called reactant. They are written at the left side of an arrow that represent a change while the compound or elements that formed after the chemical change are called product. They are written at the right side of the arrow.

▪️\underline{ \bold{ \sf{ \purple{For \: example}}}}

Using wolfram alpha or some other reference, determine which of these elements would be liquid at 525 k (assume samples are prot
romanna [79]
The choices for this problem are bismuth, Bi; platinum, Pt; selenium, Se; calcium, Ca and copper, Cu. I think the correct answer would be selenium. The melting point of bismuth is at a temperature of 544.4 Kelvin. At a temperature of 525 K, it would exist as solid. Platinum melts at 2041.1 K. At 525 K, platinum would be in solid form. Selenium has a melting point at 494 K so that at a temperature of 525 K, it would exist in its liquid state. Calcium has a melting point of 1112 K so it would exist as solid at 525 K. Copper has a melting point at 1358 K, so it would still exist as solid at a temperature of 525 K. Therefore, the answer would only be selenium.
