Engineers find a new metal that is stronger than steel but much lighter. this
material is also significantly cheaper than what is currently used for most
aircraft, available in large quantities, and easy to manufacture. the engineers
ore excited because this new metal will lower companies cots of buying and
operating airplanes. what is the best step for the engineers to make next?
a. begin marketing a plane constructed from this metal,
o
b. conduct a flight test for an airplane made from this metal,
c. decide whether or not to paint the new aircraft
o
d. begin to design an airplane using this metal,

Ithink carbon dioxide, i am not completely sure.tell me if i am wrong.

Reducing agents  oxidized by the reaction 

First up write the aim
then write the materials reqd.
then the procedure which you follow
then observation
then conclusion
then you can write lab safety rules or precautions(you can avoid if u want).
lemme' give an example
aim: to observe the double displacement reaction
materials reqd: bacl2 and na2so4, test tubes and a dropper
procedure:
1. take bacl2 in a test tube and na2so4 in the other.
2. then pour bacl2 into na2so4 solution.
3. observe
observation:
you will see that a white precipitate is formed called baso4. along with that common salt or nacl is formed.
the equation is
bacl2+na2so4=baso4+2nacl
conclusion:
a double displacement reaction is observed.
hope it
