I would say that Candace's answer is d. wide-ranging. she didn't get the exact / precise (they mean the same thing) answer.
<span>Answer Choices:
A) Ca
B) O
C) Cl
D) s</span>
<span>the formula is Li2X, so the charge on the X anion must be 2-
the ion is X2- elements in group 6A form monatomic ions with a 2- charge. In your list that is O or Po
If the element can accomodate 12 electrons then it can have an expanded octet. Only elements in period 3 and higher can have expanded octets.
So you are looking for a group 6A element in period 3 or higher.
cA would not intereact with LI BECAUSE ITS A METAL The only element that fits the bill is D) S</span>
It's a cube so the volume = edge^3
Volume = 2.5^3 cm^3 = 15.625 cm^3
density = mass / volume = 42.20 / 15.625 = 2.70 You have 3 places of accuracy.
density of object = 2.70 grams / cm^3 <<<<=== answer.
Answer:
MnO- Manganese Oxide
Explanation:
Empirical formula: This is the formula that shows the ratio of elements
present in a
compound.
How to determine Empirical formula
1. First arrange the symbols of the elements present in the compound
alphabetically to determine the real empirical formula. Although, there
are exceptions to this rule, E.g H2So4
2. Divide the percentage composition by the mass number.
3. Then divide through by the smallest number.
4. The resulting answer is the ratio attached to the elements present in
a compound.
Mn O
% composition 72.1 27.9
Divide by mass number 54.94 16
1.31 1.74
Divide by the smallest number 1.31 1.31
1 1.3
The resulting ratio is 1:1
Hence the Empirical formula is MnO, Manganese oxide
It is scandium or titanium iron chroniclemium vanadium manganese
