Agiven substance is a white, granular solid at 25 °c that does not conduct electricity. it melts at 750 °c wand the melt conducts electricity. it dissolves easily in water and produces a conductive solution. identify the type of crystal and justify your answer.

Ionic crystal

Explanation:

An ionic crystal has a high melting point. In an ionic crystal, the ions are tightly held in electrostatic attraction by their oppositely charged neighbors forming a rigid three dimensional lattice. However, when this solid melts, the rigid crystal structure collapses and the individual ions become free and mobile. Hence the melt conducts electricity.

it should be all of them because it asks if you included all of those in your answer

explanation:

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
