Marcus is taking advanced placement chemistry in high school because he loves science and is fascinated by chemistry experimentation. Wade is taking advanced placement chemistry because his guidance counselor told him he needed to if he intended to apply to a pre-med program at a competitive university. Marcus is motivated by motivation, while Wade is motivated by motivation

Marcus is motivated by intrinsic motivation, while Wade is motivated by extrinsic motivation.

Explanation:

Simply put, intrinsic motivation is the motivation that comes from within. It does not need any external factors to exist. You are motivated by your own feelings, and you do something because you really enjoy it.

On the other hand, extrinsic motivation comes from factors outside the self. If money and fame motivate you, for instance, that means you are extrinsically motivated.

According to the passage, Marcus is taking advanced placement chemistry because he truly enjoys it. Marcus' motivation is intrinsic. However, Wade is taking the same subject because he was told it will be helpful in the future. Wade's motivation is extrinsic.

well its not not rising unemployment and falling inflation.

hope this good !

question - in 1827, john walker, a druggist in a small english town, tipped a splint with sulphur, chlorate of potash, and sulphid of antimony, and rubbed it on sandpaper, and it burst into flame. the druggist had discovered the first friction-chemical match, the kind we use to-day. it is called friction-chemical because it is made by mixing certain chemicals together and rubbing them. although walker's match did not require the bottle of acid, nevertheless it was not a good one. it could be lighted only by hard rubbing, and it sputtered and threw fire in all directions. in a few years, however, phosphorus was substituted on the tip for antimony, and the change worked wonders. the match could now be lighted with very little rubbing, and it was no longer necessary to have sandpaper upon which to rub it. it would ignite when rubbed on any dry surface, and there was no longer any sputtering. this was the phosphorus match, the match with which we are so familiar. according the paragraph what was the benefit of the new phosphorus match? it burst into flame when rubbed on sandpaper. it was made by mixing chemicals. it could be ignited on any dry surface. it threw fire in all directions.

answer - matches required natural chemicals
