PLEASE HELP ME WITH BOTH AS They are part of 1 question and i really need help:( . I only have limited questions to ask so pls help asapp. Just a heads up, they are different questions tho but calculated together I will definitely consider giving thumbs up.
Please help
(4b-102) Only using the list of ions below, form two ionic compounds that would be soluble in water, and two ionic compounds that would be insoluble in water. You should make four different compounds, but you may use ions more than once. Be sure to indicate which is which, and make sure your compounds are charge-balanced! Mg2+ Cu2+ k+ A13+ 02- PO43- CI OH For the toolbar, press ALT+F10 (PC) or ALT+FN+F10 (Mac).

Please help me with this problem I tried but I can’t get any answer right
For lab 4, we combined baking soda with vinegar, according to the chemical equation NaHCO 3 + CH 3COOH ==== NaCH 3COO + CO 2 + H 2O Consider 3 experiments: (i) 2g baking soda + 5mL vinegar, (ii) 2g baking soda + 10mL vinegar and (iii) 2g baking soda + 20mL vinegar. The amount of CO 2 produced was highest for (iii) and lowest for (i). For these experiments, which of the following is true? Vinegar ran out first Baking soda ran out first They both ran out at the same time Neither ran out
