<span> Well, here are the characteristics of ionic compounds: 1) Because of the electrostatic force of attraction (one of the strongest force), these types of compounds are usually rigid. 2) High melting points (like REALLY high compared to other colavent compounds). Ex. table salt (NaCl melts at 1714 degrees fahrenheit, while CH4 melts at -295 degrees fahrenheit). See the drastic difference? 3) Majority of ionic compounds dissolve easily in water. Notice how I say majority, as some ionic compounds are insoluble in water, and this just have to do with their intermolecular attraction between themselves relative to that between the ions and water. If for any reason you need to know these solubility characteristics, just google solubility table or something along that line. 4) When dissolved in a solution, any ionic compound can conduct electricity because the ions are floating freely and can therefore transfer electrons around. In their solid form, however, they cant because all the ions are stuck in place and cant move around. 5) Ionic compounds form a really specific shape, and all the ions are orderly placed and evenly distributed in the crystal lattice. The geometric shape of the compound is a chemical property, which means that it varies across species.</span>
the correct answer is A
A diatom is a(n) <u>Singled-celled organism</u> because it has <u>only one cell.</u>

Mass number of calcium isotopes
mass numberi the number of proton + neutron
number of proton for calcium is 20 regardless of isotopes
hence the only difference between calcium isotopes are rhe number of neutron
I think it’s C
a, sugar can’t conduct electricity
b, you don’t want to conduct electricity with something wet
salt can be a conductor of electricity
Only the amount of gas is held constant.
