Will give brainliest1. which element(s) are not balanced in this equation? fe2o3 + 3 co → fe + 3 co2 2. nitrogen gas (n2) and hydrogen gas (h2) combine to form ammonia (nh3). which equation correctly represents this reaction? a. n2+ 3h2 → 2nh3 b. 2nh → n + 3h2

1. would be the element "Fe"

2. Would be A since of course the end is balanced and makes it N2H6 and a regular ammonia atom would have one nitrogen and 3 hydrogen making it NH3 and if you make N2H6 into its empirical form you will get NH3.

1) The unbalanced elements in this equation is Fe and O. On the left side of the equation there are 2 Fe's and on the right there is only 1 and on the left there are 3 O's but on the right there are 6 because O2 three times is 2x3 and that equals 6.

2) A would be the correct answer because in order to keep the equation balenced there has to be 2 ammonia (NH3) molecules and 3 hydrogen (H2) bonded molecules.

i need mutiple choices

the food using pesticides in the future will harm you by giving you diseases like cancer or something since they have things that we should not eat in it like chemicals or pesticides. that is why organic food is more expensive because they take the time to make it right and healthy for you to eat.
