Write net brønsted equations that show the acidic or basic nature of the following solutions in water. for polyprotic species (vitamin c, lemon juice, and washing soda), show only one proton transfer. remember that spectator ions are not included. (use the lowest possible coefficients. omit states-of-matter in your answer.)
(a) vinegar (acetic acid, hc2h3o2)
(b) bleach (sodium hypochlorite, naocl)
(c) ammonia (nh3)
(d) vitamin c (ascorbic acid, h2c6h6o6)
(e) lemon juice (citric acid, h3c6h5o7)
(f) washing soda (sodium carbonate, na2co3)

The diagrams show objects’ gravitational pull toward each other. which statement describes the relationship between diagram x and y? gravity attracts only larger objects toward one another. gravity attracts larger objects only if they are close to one another. if the masses of the objects increase, then the force between them also increases. if distance between the objects increases, then the amount of force also increases.
