The earths crust is above sea level and the oceanic is not.
Answer:
B. They bond identical atoms together
Explanation:
Metallic Bond: This is the bond that exists among the atoms of the metal. This is a type of electrostatic attraction between conduction electrons of metallic atom and their positively charged metal ions.
<em>(figure attached)</em>
Example:
Copper is a metallic element and its atoms consist of metallic bond among their selves.
Options A, B, D are not correct as all states for a kind of ionic bond formation.
Ionic bond:
It form by the complete transfer of electron from one atom to other
It is formed among two atoms of different electronegativities.
Also metals are electro-positive and non -metals are electro-negative so they form ionic bond.
Example is NaCl where sodium is a metal and Chloride is non-metal and they from ionic bond.
Copper 2
Just like you how you would say Cu(I) as copper one, you would say Cu(II) as copper two. Nothing fancy.
Answer:
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to realize this is a question about titration, which base solved by knowing that the HCl reacts with the NaOH in a 1:1 mole ratio, and therefore, we can write the following:
Thus, we solve for the molarity of the base, NaOH, as shown below:

The magnesium dissolves to form magnesium chloride and hydrogen gas is released.
Mg + 2HCl -----> MgCl2 + H2(g).
