Question

3 the effects of mixtures of chemicals causing hazardous materials is called select one: a. reactivity. b. cercla. c. synergism. d. chronic toxicity.

Explanation:

Reactivity refers to how likely a substance is to react chemically. "Cercla" is not a relevant term here. Synergism occurs when the combined effect of chemicals is greater than the sum of their individual effects, which is what the question describes. Chronic toxicity is about long - term harmful effects of a single or multiple substances, not specifically about the combined effect of mixtures causing hazardous results in the way described.

Answer:

C. synergism
