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 bolded paragraph, what was the benefit of the new phosphorus match? (5 points)

Answer 1

The benefit of the new phosphorus match was that it could be lighted with very little rubbing and was no longer necessary to have sandpaper upon which to rub it.

Step-by-step explanation:

It would ignite when rubbed on any dry surface, and there was no longer any sputtering. In summary, it was a more convenient and reliable match for ignition.
