All samples of sodium chloride have a ratio of one sodium ion for one chloride ion. What must be true of the total (net charge) for any sample of sodium chloride?
When you add up the charges for all the positive and negative ions you get a net (total) charge of +9.
When you add up the charges for all the positive and negative ions you get a net (total) charge of -9.
When you add up the charges for all the positive and negative ions you get a net (total) charge of zero.
All samples of calcium chloride have a ratio of one calcium ion for two chloride ions. What must be true of the total (net charge) for any sample of calcium chloride?
When you add up the charges for all the positive and negative ions you get a net (total) charge of +10.
When you add up the charges for all the positive and negative ions you get a net (total) charge of -10.
When you add up the charges for all the positive and negative ions you get a net (total) charge of zero.
All samples of aluminum oxide have a ratio of two aluminum ions for three oxide ions. What must be true of the total (net charge) for any sample of aluminum oxide?
When you add up the charges for all the positive and negative ions you get a net (total) charge of +12.
When you add up the charges for all the positive and negative ions you get a net (total) charge of -12.
