D) Attraction between oppositely-charged ions.
In ionic bonds, one atom is negatively charged, and one atom is positively charged. The positively charged atom gives its electrons, and the negatively charged atom receives the electrons--thus, the opposite charge attracts them to one another and holds them together. That simple.
From Earth's<span> density we can estimate what elements must compose the </span>Earth; an iron core<span> just happens to estimate </span>Earth's<span> mass the best. Now from energy waves, geologists use seismometers to measure movements in </span>Earth's<span> interior (e.g. Earthquakes), These energy-waves form compressional and shear waves</span>
IT ACID OR BASE THATS WHAT WOULD PUT SEE YA
Answer:
Barium carbonate powder is stirred add pulp in the entry, the vitriol that the adds solubility then reaction that makes the transition is filtered and is obtained the barium sulfate filter cake and liquid after the transition.
Explanation:
Mass of an electron =9.1×10−28g
∴ mass of one mole
=9.1×10−28×6.02×1023
=54.78×10−4g
