Litmus paper is made from water-soluble dyes which are extracted from lichens. this paper is used as an acid-base indicator. which of these common household substances would turn blue litmus paper red? a) ammonia eliminate b) vinegar c) baking soda d) distilled water

Blue litmus paper turns red in the presence of an acidic solution/compound. An acid is any substance with a pH level less than 7.

Ammonia is a moderately basic solution. It has a pH greater than 7. Therefore, it will not turn blue litmus paper red.

Baking soda is also a basic substance with a pH greater than 7. It also will not turn blue litmus paper red.

Distilled water is a neutral solution. It has a pH of 7, and it will not react with the litmus paper to change its color.

That leaves us with vinegar. Vinegar is an acid with a pH of less than 7. It will turn blue litmus paper red.

calculate how many grams of ammonia can be produced from 4.21 grams of

n2 + 3h2 = 2nh3

my answer:

25.0g n2 x (1 mol/ 28.0gn2) x (2 mol nh3/ 1 mol n2) x (17.0g nh3/ 1 molnh3) = 30.36g n2

25.0g h2 x (1 mol h2/ 2.00g h2) x (2 mol nh3/ 3 mol h2) x (17.0g nh3/ 1 mol nh3) = 141.67g h2

lr = n2

answer: a chemical reaction

explanation:

im not wrong
