Question

A certain element has a melting point over 700 ∘C and a density less than 2.00 g/cm3. Give one possible identity for this element.

Answer 1

The requested element with a melting point over 700 °C and a density below 2.00 g/cm³ cannot be conclusively identified with the provided information, but aluminum is the closest match if some variance in density is acceptable.

Step-by-step explanation:

The question is asking for the identity of an element with specific properties, namely a melting point over 700 °C and a density less than 2.00 g/cm³. From the reference information provided, the most likely candidate for this element is aluminum (Al). Aluminum has a density of 2.70 g/cm³ and a melting point of 933.5 °C, which does not fit the exact criteria. However, due to a lack of other elements matching the specifications given and assuming a potential typo or error in the reference information, aluminum comes closest to the specified properties. If we disregard aluminum due to its higher density, there is no element listed that meets both criteria exactly. Therefore, without complete information or assuming a typographical error, we can’t definitively identify an element that meets both given conditions strictly. However, aluminum is the closest element that mostly matches the description if there is some tolerance for the density value.

Answer 2

If a certain element has a melting point over 700 ∘C and a density less than 2.00 g/cm3, one possible identity for this element is Calcium. Thank you for posting your question. I hope this answer helped you. Let me know if you need more help.
