PLL HEL Balance the chemical equation below using the smallest possible whole number
stoichiometric coefficients.

Q1= C(s)+H2(g) -> C2H6(g)
Q2= NH3(g)+O2(g)-> HCN(aq)+H2O(l)

An engineer decides to use a slightly weaker material rather than a stronger material, since she knows that the stronger material can break suddenly. this is an example of what? a choosing a material that will show warning before it fails b using composite materials that combine strength c using a material for multiple applications d using design techniques that increase efficiency and reduce cost
