for the reaction shown, draw the product of one mole of reagent adding across the triple bond, and then draw the product of a second mole of reagent.

A+b→2c when the reaction begins, the researcher records that the rate of reaction is such that 1 mole of a is consumed per minute. after making changes to the reaction, the researcher notes that 2 moles of a are consumed per minute. what change could the researcher have made to effect this change?

Compare and contrast physical changes with chemical changes.

May someone me with these science questions
