2. (4 pts) There are N, molecules in the air. There is also liquid N2. Draw a molecular level picture that shows the difference between the two

3. (4 pts) CH3CH2OH (shown below) is soluble in water. Draw a molecular level picture
that represents after CH3CH2OH has been dissolved in water.

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them  

catya your not at all which answer i've seen you do this on another question!
