Lead can be prepared from galena [lead(ii) sulfide] by first roasting the galena in oxygen gas to form lead(ii) oxide and sulfur dioxide. Heating the metal oxide with more galena forms the molten metal and more sulfur dioxide. Required:
a. Write a balanced equation for each step.
b. Write an overall balanced equation for the process.
c. How many metric tons of sulfur dioxide form for every metric ton of lead obtained?

I don't really have an answer it's very confusing sorry

Explanation:

... ;w;

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or
