When wood is burned How does the mass of the products compare with the mass of the reactants?

The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. For example, when wood burns, the mass of the soot, ashes, and gases equals the original mass of the charcoal and the oxygen when it first reacted. So the mass of the product equals the mass of the reactant.

What is positive and negative image?

A positive image is a normal image. A negative image is a total inversion, in which light areas appear dark and vice versa. Film negatives usually have less contrast, but a wider dynamic range, than the final printed positive images. The contrast typically increases when they are printed onto photographic paper.

How an image is created on a negative?

Negatives are usually formed on a transparent material, such as plastic or glass. Exposure of sensitized paper through the negative, done either by placing the negative and paper in close contact or by projecting the negative image onto the paper, reverses these tones and produces a positive photographic print.

What is the negative of a picture?

You have now captured an image on your film. When that film is processed, it reverses the tones of the subject. In simple terms, the image is dark where the subject was light, and light where the subject was dark. That resulting image is known as a negative.
