Answer is: D. iron rusting.

Balanced chemical reaction of forming rust: 4Fe + 3O₂ → 2Fe₂O₃.

The mass of the rusted nail, for example, equals the mass of iron and the oxygen from the air it reacted with to form the rust.

Alcohol burning and an explosion are exothermic (energy is released) and very fast reactions.

Iron rusting is the answer because it take a longer time for iron to rust than it take for the other things.

TRUE OR FALSE?<br><br> An exothermic reaction could be written as: <br> heat + A + B -----&gt; AB
sukhopar [10]
The correct answer for this statement would be FALSE. It is considered false since exothermic reactions release energy, therefore, this energy can be considered more of a product, instead of the reactant. Hope this is the answer that you are looking for.

Which is a positive effect of the technology advance of going from a compass to a gps
egoroff_w [7]

Answer:

Compass - Gps                              

Explanation:

I belive the pro's                                      and cons are

                                         GPS             you are trusting a little man made device

the direction you                               to give you directions

are going on                                        and that it won't break or die

a device not a paper map

                                                Compass

You can see north east south and              it is usually carefully crafted for                                                                                                                                                                          o                                                                     outdoors but it has no roads and

west on the compass and                          if given no directions, extremely

you can see the roads follow directions                  confusing until you learn it

like go south then east.

If 25.0 g NO are produced, how many grams of nitrogen gas are used?
ivanzaharov [21]

Based on the assumption that the reaction involves N and O to produce NO, if 25.0 g of NO are produced, the amount of N gas used would be 11.66 grams

<h3>Stoichiometric calculation</h3>

From the equation of the reaction:

       N + O ---------> NO

Mole ratio of N to NO is 1:1

Mole of 25.0 g of NO = 25/30.01 = 0.833 moles

Equivalent mole of N = 0.833 moles

Mass of 0.833 moles N = 0.833 x 14 = 11.66 grams
