An ionic compound is composed of anions and cations. A cation is a positively charged ion, and an anion is the opposite. A metal is composed of two or more cations. Since you need at least one cation and one anion for an ionic compound, the metal is not ionic.
Answer:
False.
Explanation:
Scientific theories and hypothesis are all tentative. Science tries to prove something is either true of false and come up with answers (as much as we can) for many problems. Sometimes they are made based on limited data or information. Over the years, we come up with need findings discoveries which are able to give us more information and give us better answers. There have been a couple of scientific laws which had to be completely revised or discarded after new observations. An example of this would be the Laws of Thermodynamics. A couple of the laws have been changed over the decades after scientists made new disoveries and observations.
Darwin's Theory of Natural Selection has been divided into five parts to explain clearly how evolution happens in nature. 1. Organisms produce more offspring than actually survive. Organisms can die from many causes: disease, starvation, and being eaten, among other things so C Your welcome
Answer:
Volumes can have the same volume but different masses if they have different densities. For example, a 10 x 10 x 10 block of lead has the same volume as a 10 x 10 x 10 block of pine wood, but the lead block weighs 22.6 times more than the pine block. Indeed, the density of lead is high enough that the lead block will sink in water, whereas the pine block's density is low enough that the pine block will float in water.
Volume is a measurement, the units are cubic metres or cubic centimetres. Litres = 1000 cm3
Mass is a measurement, the units are grams, kilograms.
^^^^^^^^^^^^^^^^^^
to that answer.
Mass is not weight. it is the amount of matter an object takes up. Therefore, saying that a lead block weights 22.6 times more than the pine block does not answer how an object can have different masses but the same volume. :D
