Metals lose electrons
Non metals gain electrons
They do this to gain a full outer shell in order to become stabilised
Answer:
3 moles of Argon
Explanation:
The molar mass for argon is 39.948 g/mol
Sound travels fastest through solids.
Answer:
I think the answer might be because Atomic mass is the weighted average of the naturally occuring isotopes. Also with the fact that it's not an integer, it would almost never be a whole number
Explanation:
Substance's physical characteristics while separating a mixture of materials. The solubility of salt and sand is its most evident characteristic. Insoluble in water is sand. In water, salt is soluble. Therefore, you would take these actions to separate them.
Stir the mixture well after adding the water. (While the sand will not dissolve and will instead stay as a solid, the salt will dissolve and form a salt solution). Filter the combination. (Salt will flow through with the water since it has dissolved; sand has not yet done so and will not be able to pass through the filter paper). The salt solution should be heated until all the liquid has evaporated. Crystals of solid salt will last. One or more pure components of differing compositions make up a combination. Heterogeneous and homogeneous mixtures are the two types of mixtures. While homogeneous mixtures seem consistent throughout, heterogeneous mixtures have clearly discernible components. A solution, which can be a solid, liquid, or gas, is the most typical kind of homogenous mixture.
