did you ever get the answer lol
because 72:96 is an equivalent of 12:16 and that if you multiply 12 times 6 you get 72 and if you multiply 16 by 6 you get 96
For #1 the answer is dependent relationship . 2. answer is independent relationship . the last question the answer is dependent.
1) baking soda (NaHCO₃ - sodium bicarbonate) is white, solid, crystalline salt or <span>appears as a fine powder.
2) vinegar is mixture of acetic acid (CH</span>₃COOH) and water (H₂O). Vinerar is colourless liquid with <span>sour taste and pungent smell.
3) Chemical reaction: </span>NaHCO₃ + CH₃COOH → CH₃COONa + CO₂ + H₂O.
Jane should see bubbles of carbon(IV) dioxide.
4) sodim acetate (CH₃COONa) is solid and carbon dioxide (CO₂) is gas.
5) Jane can put burning match over reaction, the fire on the match is going to put out because of carbon dioxide.
