Answer:
You need to add 3 100 pound bags of Parkerâs Premium Starter and 5 100 pound bags of Vigoro Ultra Turf fertilizer
Explanation:
You can obtain 3 equations. One for each compound:
For N:
177 pounds = 29x + 18y <em>(1) </em>
<em>-</em><em>Where x are bags of Vigoro Ultra Turf fertilizer</em><em> </em><em>and y are bags of </em>Parkerâs Premium Starte-
For P₂O₅:
134 pounds = 3x + 25y <em>(2)</em>
For K₂O:
42 pounds = 4x + 6y <em>(3)</em>
Replacing (1) in (2):
134 = (531/29 - 54y/29) + 25y
3355/29 = 671y/29
<em>y = 5 bags</em>
Thus,
<em>x = 3 bags</em>
You can replace in each equation to prove that this is the right result.
I hope it helps!

Molecular is every element present in the compound eg C2H6, empirical is the smallest whole number ratio of elements in a compound so that would be CH3 as you divide by the highest common factor. Some compounds only have 1 formula if they are simple or have no common factors. Eg methane, CH4 is its molecular and empirical because its the simplest whole number ratio and includes every element in the molecule
Answer:
Boron (B) Atomic Mass: 10.811
Explanation:
The number of protons and electrons are the same, always. You can find the atomic mass by looking at the periodic table for that atom: 10.811
Answer:
9 moles of ions
Explanation:
Our compound is: CaCl₂(s)
We dissociate it:
CaCl₂(aq) → Ca²⁺ (aq) + 2Cl⁻(aq)
Per 1 mol of chloride, we have 1 mol of calcium cation and 2moles of chlorides, so in total we have 3 moles of ions.
Therefore in 3 moles of chloride, we would have 9 moles of ions (3 . 3)
