No
Magnesium Chloride is MgCl2
The method I use to name ionic compounds is 'swap and drop'
Mg oxidation number is +2 and Cl oxidation number is -1
Mg^2+ Cl^-1
'swap'
Mg^1 Cl^2
'drop'
MgCl2
<span>3.10 moles SiO2 (1 mole Si/1 mole SiO2)(6.022 X 1023/1 mole Si) = 1.87 X 1024
</span><span>= 1.20 X 1023 atoms of oxygen.</span>
Answer:
1.874 M.
Explanation:
<em>Molarity is defined as the no. of moles of a solute per 1.0 L of the solution.</em>
<em />
M = (no. of moles of solute)/(V of the solution (L)).
<em>∴ M = (mass/molar mass)of NiCl₂/(V of the solution (L)).</em>
<em></em>
∴ M = (mass/molar mass)of NiCl₂/(V of the solution (L)) = (85.0 g / 129.59 g/mol)/(0.35 L) = 1.874 M.
The correct answer for the question that is being presented above is this one: "A a naturally occurring, inorganic solid that has a crystal shape and a definite chemical composition." The correct definition of minerals is that it is a naturally occurring, inorganic solid that has a crystal shape and a definite chemical <span>composition</span>
