What is the name for the compound with the formula BaSO4? |
Barium sulfate |
|
Which one of the pairs correctly matches the ion’s name with its formula? Nitrate, NO2— Carbonate, CO32- Chlorate, ClO4— Sulfate, SO32- |
Carbonate, CO32- |
|
What formula represents the compound formed from ammonium and phosphate ions? |
(NH4)3PO4 |
|
Ammonium |
NH4+ |
|
Which ion will form a compound with bicarbonate in a 1:1 cation to anion ratio? |
Na+ |
|
What are the values of x and y in the formula Mgx(PO3)y? |
x = 3, y = 2 |
|
Which ion will form a compound with a 1:1 cation to anion ratio with chlorate? O2- Br— Mg2+ |
Li+ Li + will form a compound with chlorate with a 1:1 ratio to form the compound LiClO3. Chlorate has the formula ClO3—. To have a compound with a 1:1 ratio with chlorate, you need a cation with a 1+ charge. |
|
Which ion can correctly complete the formula Al2(__________)3? Phosphate Nitrate Ammonium Dichromate |
Dichromate Dichromate, Cr2O72-, will complete the formula and form Al2(Cr2O7)3. Aluminum has a 3+ charge and the anion needs a 2- charge to balance the charges in the compound. Two aluminum ions (2 × 3+) have a total charge of 6+ to balance with the 6- charge of the three dichromate ions (3 × 2-). |
