Answer:
2Fe + O₂ -------------------> 2FeO
8 mol Fe produce
8 mol Fe * 2 mol FeO / 2 mol Fe = 8 mol FeO
Mass of FeO = 8 mol FeO * 71.85 g/mol = 574.8 grams FeO
Explanation:
Having 8 mol of Iron means 8 moles of iron oxide can be produced. Each mole of iron oxide has a molecular weight of 71.85 grams. Therefore, 8 moles of iron oxide should weight 574.8 grams.
B. Don't take up most of the space in an atom,
95.21 grams.
Add the atomic mass of each element present. (If there is more than one atom of an element, multiply the element's atomic mass by the number of that element's atoms.)
The molar mass is 64.07g/mo
Answer:
The comparison is between Fuel canister (diethylene glycol) or Tea candle (paraffin)
The answer is tea candle( paraffin)
Explanation:
A fuel’s efficiency is based on its reaction with air(oxygen). It is said to be efficient when it burns well when exposed to air(oxygen).
Tea candle( paraffin) burns more efficiently in the presence of oxygen when compared to fuel canister( diethylene glycol) due to the hydrogen bonds in the molecules of fuel canister( diethylene glycol) making it more stable and having a lesser affinity to air (oxygen) than those of tea candle (paraffin).
