The correct answer is C, Al\u2082X\u2083.<\/section>\n
The formula Na\u2082X indicates that the anion X has a charge of -2 (X\u00b2\u207b) because sodium (Na) has a charge of +1, and there are two sodium ions balancing the charge of one X anion (2 * +1 + charge of X = 0, so charge of X = -2). Aluminium (Al) forms ions with a charge of +3 (Al\u00b3\u207a).<\/section>\n
To form a neutral compound between Al\u00b3\u207a and X\u00b2\u207b, the total positive charge must equal the total negative charge. The least common multiple of the absolute charges (3 and 2) is 6. We need two Al\u00b3\u207a ions to get a total positive charge of +6 (2 * +3) and three X\u00b2\u207b ions to get a total negative charge of -6 (3 * -2). Therefore, the formula for the aluminium salt of anion X is Al\u2082X\u2083.<\/section>\n","protected":false},"excerpt":{"rendered":"
