Engineers create 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. What is
the best step for the engineers to make next?
A. Design a new airplane with this new material.
B. Build a new plane with this material.
C. Decide what profit margins they would like to see for this new
technology.
D. Test the new airplane in a wind tunnel test.

put the answers   and i could answer.

that's what i got you can count the number of atoms

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
