What positive attitude does robert bunsen have? ?

Robert Bunse's positive attitude was to research how he could improve a tool that had already been created by Faraday.

Explanation:

Robert Wilhelm Eberhard Bunsen was dedicated to research in the fields of chemistry, physics and geology. Researching, in 1834, the cacodylic series, Bunsen discovered that iron oxide is a powerful antidote against arsenic and its compounds. Based on this discovery, Bunsen established the premises for the investigation of organometallic compounds and presented detailed observations about the blast furnace gases and the recommended techniques for measuring and controlling industrial production.

But the improvements provided by Bunsen do not stop there. He also reformulated and considerably improved the gas burner created by Faraday. Busen created such an improvement in this equipment that even today it bears his name, the Bunsen Burner.

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.
