This is what I got hope this makes sense:There is 1 mol of Mg 2+ ions in one mole of MgCl2, we can get that from the formula.
Multiply 3.00 moles by 6.022x10^23 to get moles of MgCl2.
There are 6.022x10^23 ions in one mole of substance.
(3.00)(6.022x10^23)
=1.81x10^24 Mg 2+ ions
Hope it helps though
Explanation:
pH is used to measure the concentration of H+ ions ([H+]) and therefore, whether a substance is acidic or basic (alkaline). Solutions with a pH of less than seven are acidic, while those with a pH greater than seven are basic (alkaline).
Answer:
D. Silicon
Explanation:
A anion is a negatively charge ion resulting from the imbalance of protons and neutrons where there are more electrons than protons. Silicon has 4 valence electrons and is more likely to form an ionic bond with another atom(s) that will give it the 4 electrons it needs to become stable.
C because I’m space there’s no gravity meaning things are weightless
They are called ISOTOPES.
