The electromagnetic waves described as both beneficial and detrimental to human health are _____ waves.

Answers

Answer 1
Answer:

The answer is X- rays. The benefit of X rays is their use in medical imaging. This is because of their property to penetrate some matter, such as tissues, differentially. This property is significant in disease diagnosis. However, X rays are detrimental to the human health, especially in above-recommended doses. The high energy of X rays can damage DNA in cells and cause mutations that lead to cancer.

Answer 2
Answer: I'm not positive but I'm pretty sure its Light waves.

A liquid fuel mixture contains 30.35% hexane (c6h14), 15.85% heptane (c7h16), and the rest octane (c8h18). what maximum mass of carbon dioxide is produced

Answers

To answer this item, the carbon dioxide produced can be determined by determining first the mass of carbon available for the reaction. Let our basis be 100g of fuel mixture.

carbon in hexane = (100 g)(0.3035)(6*12/6*12 + 14) = 25.41
carbon in heptane = (100 g)(0.1585)(7*12/7*12+16) = 13.31
carbon in octane = (100 g)(0.538)(8*12/8*12+18) = 45.3

The mass of carbon is 84.02. Each 12 g of carbon is present in 44 g of carbon dioxide. 

     (84.02 g carbon) x (44 g of carbon dioxide/ 12 g of carbon) 
   = 308.07 carbon dioxide/100 g of mixture

Answer: 308.07 g carbon dioxide / 100 g of mixture
