Ionic compounds are compounds that are formed together by a cation and an anion. A cation is an ion with a positive charge. For example, Na+ and Ca2+. An ion has a negative charge, like Cl- and OH-. There is a greater chance of forming an ionic compound when they have a great difference in electronegativity, the ability to attract electrons toward itself. In the periodic table, elements that are opposite to each other, more likely found in opposite sides, would be more apt to form an ionic compound. Example would be NaCl and CaCl2 or Ca(OH)2.
It is in an incorrect spot i think
Answer:
1.14 M
Explanation:
grams/molar mass = ans. / volume
317/110.98=2.86/2.50=1.14 M

Answer:
Atoms of the same element, containing the same number of protons, but different numbers of neutrons, are known as isotopes. Isotopes of any given element all contain the same number of protons, so they have the same atomic number (for example, the atomic number of helium is always 2(
Carbon dioxide is a main greenhouse gas, found in car exhaust pipes. Methane and nitrous oxide is another type of greenhouse gas. Oxygen is the only clean gas out there because we need it to survive. Therefore, the only gas that is not a greenhouse gas is (c) oxygen.
