<span>I am sure these answers are correct cause I've checked all of them. Here they are :
1) The thing which might h</span>appen to the rest of the water is that 61% of that water leaves the ground through evapotranspiration and <span>38% will flow into the Atlantic Ocean.
</span>
2) The four states which receive drinking water from Florida are : <span> South Carolina, Georgia, Alabama, Mississippi
3) The</span> reason why people in Florida wanted to get rid of the water in certain areas is abundance of wetlands. I think there is one more, if it is acceptable I suggest you using this - frequent flooding.<span>
4) </span><span> The negative result of the changes which people made to get rid of the water is the first sign of </span>drought.
5) The thing that has been done to try and improve those mistakes was creating a tool which looked like a dam to prevent dfficulties with <span>navigating the state.
Hope that helps.</span>

These problems are a bit interesting. :)
First let's write the molecular formula for ammonium carbonate.
NH4CO3 (Note! The 4 and 3 are subscripts, and not coefficients)
17.6 gNH4CO3
Now to convert to mol of one of our substances we take the percent composition of that particular part of the molecule and multiply it by our starting mass. This is what it looks like using dimensional analyse.
17.6 gNH4CO3 * (Molar Mass of NH4 / Molar Mass of NH4CO3)
Grab a periodic table (or look one up) and find the molar masses for these molecules! Well. In this case I'll do it for you. (Note: I round the molar masses off to two decimal places)
NH4 = 14.01 + 4*1.01 = 18.05 g/mol
NH4CO3 = 14.01 + 4*1.01 + 12.01 + 3*16.00 = 78.06 g/mol
17.6 gNH4CO3 * (18.05 molNH4 / 78.06 molNH4CO3)
= 4.07 gNH4
Now just take the molar mass we found to convert that amount into moles!
4.07 gNH4 * (1 molNH4 / 18.05 gNH4) = 0.225 molNH4
Last option that is none of above is right answer.
