PLEASE HELP ME Complete the following reactions, balance them and calculate how many grams of the first product you
would get if you started with 5.0 g of the first reactant, assuming you have enough of the other
chemicals. SHOW WORK, including correct formulas, how you calculate molar mass and conversions
1. C2H5OH + O2  CO2 +
2. Magnesium hydroxide + hydrochloric acid --- magnesium chloride +
3. Ammonium carbonate - ammonia + + H2O
4. Copper(I)perchlorate + Zn -- Cu +
5. Nitrogen + hydrogen -- ammonia

1. 1 mole of anything contains 6.022x10^23 pieces  

d  

2. a  

3. c, number  

5. 1.24x10^24atoms / 6.022x10^23atoms/mole = 2moles h2 atoms  

6. fe2br3 mass = 2moles x mass fe + 3 moles x mass br  

molar mass = grams / number of moles = g/mole  

to find moles = g / molar mass  

to find mass = g = molar mass / moles

? you expect us to answer this? ? this is your schoolwork, i don't think we can with this, i think it would considering being

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.
