<span>Consider the following reaction:
2CH3OH(g)→2CH4(g)+O2(g)ΔH=+252.8kJ
Calculate the amount of heat transferred when 27.0g of CH3OH(g) is decomposed by this reaction at constant pressure.
27.0 g </span>CH3OH(g) (1 mol/ 32.05g) = 0.84 mol CH3OH(g)
ΔH =+252.8kJ = Q = 0.84 mol (252.8kJ) = 213 kJ
Answer:
2. terms in science are derived from greek or latin worda
Explanation:
because it's helpful to create new words, for different diseases or discoveries from a "dead language" which won't be ever changing
Oxygen(O)
Explanation:
Oxygen is the most reactive of all the listed elements. One can determine their reactivities based on the electronegativity values.
- Every element combines with one another to attain stability like the noble gases.
- Electronegativity is the relative ease with which the atoms of elements attracts valence electrons in a chemical bond.
- On the pauling's electronegativities table of elements, carbon is 2.5, oxygen 3.5 and Cl is 3.0
- Oxygen will have the highest reactivity and the most tendency to combine with other atoms.
