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.
Among the different types of scientific knowledge Hypotheses are likely to be modified or discarded most frequently , long ago in the 1600's scientists discarded the phlogiston theory because the new evidence didnt support it.
Answer:
density = 7.83g/mL
It will sink in water.
Explanation:
D = mass/volume
94/12 = 7.83 g/mL
density of water is 1g/mL
Object is more dense than water, meaning it will sink.
Answer:
The answer is "
".

The answer for the first question would be water. It is the substance that is a compound since it is made up of different elements. For the second item, i think the best answer is phosphorus and nitrogen. They are the limiting nutrients. For the last item, the correct answer is reservoirs.
