Question

question 18 (0.5 points) give the formula from the systematic name (a mixed ion salt) sodium potassium sulfate _1_ _2_ _3_ a. na2 b. na c. k3 d. k2 e. so3 f. (so3)2 g. (c2h3o2)2 h. c2h3o2 i. hso3 j. c2 k. c3 l. po3 m. hpo3 n. h2po3 o. oh p. (oh)2 q. k r. so4 s. (so4)2 t. soap

Explanation:

Step1: Identify ion charges

Sodium ($Na^+$) has a +1 charge, potassium ($K^+$) has a +1 charge, and sulfate ($SO_4^{2 -}$) has a - 2 charge.

Step2: Balance charges

To balance the charges in the salt, we need one sodium ion, one potassium ion, and one sulfate ion.

Answer:

B. Na, Q. K, R. SO₄
