Answer:
The correct option is (d).
Explanation:
It is given that,
1$ = 1500 pesos
We need to convert 360 pesos into dimes
We can convert 360 pesos to dollars as follows:
360 pesos is equal to $0.24
Also, 1 dollar = 10 dimes
We can covert 0.24 dollar to dimes as follows :
0.24 dollar = 10 × 0.24 dimes
0.24 dollar = 2.4 dimes
or
360 pesos = 2.4 dimes
B, the height above or below sea level

a) yes Pb is more reactive that Ag, Pb before Ag
b) no, Cu after H
c) yes, Cl2 is more active than I2
4) yes, Mg is more active
13.7 (as I think)
Al ³⁺ more active than Zn²⁺, Mn can react with Zn²⁺, but not with Al ³⁺ , because Mn after Al but before Zn
<span>30.0 ml of 0.15 m K2CrO4 solution will have more potassium ions.
Let's see the relative number of potassium ions for each solution. Since all the measurements are the same, the real difference is the K2CrO4 will only have 2 potassium ions per molecule while the K3PO4 solution will have 3 potassium ions per molecule.
K2CrO4 solution
30.0 * 0.15 * 2 = 9
K3PO4 solution
25.0 * 0.080 * 3 = 6
Since 9 is greater than 6, the K2CrO4 solution will have more potassium ions.</span>
