Answer:- The formula tells us that one formula unit of this compound is composed of one calcium atom, two nitrogen atoms, and six oxygen atoms.
Explanations:- Subscripts tell us about the number of atoms of the element for which they are used. For example, here the subscript of Ca is one, it means there is one calcium atom in the given one formula unit.
When we have subscripts inside and outside the parenthesis then they are multiplied and the outside subscript is considered for all the atoms present inside the parenthesis.
Here, for the given chemical formula, the subscript of N is 1 and the subscript present outside is 2. So, 1 x 2 = 2 and for oxygen, 3 x 2 = 6
So, we have one calcium atom, two nitrogen atoms and six oxygen atoms for one formula unit of given compound.
Answer:
A- Speed = distance/time
Explanation:
Would make sense and that's what I remember
They become an ionic bond, and are weakly bonded compared to covalently bonded atoms
3. There are more oxygen atoms on the reactant side than the product side
The hypothesis can’t be a opinion or something that has nothing to do with your work
For example;if you want to see if your toilet paper is sturdy and you say “i think it will cause the commercial says it does” (wrong) answer would have to be “i infer that the toilet paper will be sturdy because it looks more resistant than other paper I’ve seen”
