I have some questions?

are these acidic, almost neutral, or basic?

vinegar, lemon juice, tomato juice, milk, and household ammonia

write a balanced equation for the reaction between CO2 gas and limewater, Ca(OH)2. what is the name of the milky precipitate that forms?

Calcium Carbonate is what forms I think.

With emphasis on the word think.

Calcium carbonate is correct:

(1) CH4 (g) + 2 O2 (g) CO2 (g) + 2 H2O (g)

(2) CO2 (g) + H2O (l) H2CO3 (aq) 2 H+ (aq) + CO3-2 (aq)

(3) Ca2+ (aq) + CO32- (aq) CaCO3 (s)

vinegar, acidic

lemon juice, acidic

tomato juice, acidic

milk, basic

household ammonia basic

Acids: Vinegar, Lemon Juice,

Alkaline (basic): Ammonia,

Tomato juice ph is 4.1 I would say acidic

Milk is neutral ph 6.6

Calcium Carbonate is CaCO3 which is a common formula for antacids.
