What happened when cortes and his soldiers first arrived in the aztec capital of tenochtitlan

The Spaniards left for Tenochtitlan, on their way they received gifts and warnings from Montezuma so that they did not arrive in Mexico, they were told that they would not be welcome because the people were angry, but Hernán Cortés ignored them and continued towards the conquest of Mexico. Later they received the most important caciques, then was Moctezuma, finally met with kind greetings and the Aztec god invited them to enter Tenochtitlan and stay in the palace of his father, they were housed with precautions in case it was a trap Cortes tried to convince Moctezuma to follow a true religion and accept his king Carlos I but Moctezuma kindly rejected everything.  

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
