Answer:
A) 2.76 x 103 kJ
Explanation:
CH3OH (I)--------->CO (g) + 2H2 (g)
Number of moles contained in 87.1g of hydrogen gas= mass of hydrogen gas/ molar mass of hydrogen gas
Molar mass of hydrogen gas= 2gmol-1
Number of moles hydrogen gas = 87.1g/2gmol-1= 43.55 moles of hydrogen
1 mole of methanol yields 2 moles of hydrogen
x moles of methanol yields 43.55 moles of hydrogen
x= 43.55 moles of hydrogen × 1 mole of methanol/2 moles of hydrogen
x= 21.775 moles of methanol
Then;
If 1 mole of methanol absorbs 128KJ of energy
21.775 moles of methanol will absorb 21.775 × 128/1 = 2.7×10^3 KJ of heat
Answer is: because alkaline metals (group IA metals) are the strongest reducing agents and most reactive metals.
Reducing agent<span> is an element or compound that loses an </span>electron<span> to another </span>chemical species<span> in a </span>redox <span>chemical reaction and they have been oxidized.
Alkaline metals tend to lose only one electron in redox reaction.</span>

Explanation:
#Atoms = (mass/atomic wt) x 6.02 x 10²³
- mass is grams
- atomic weight is grams/mole
- 6.02 x 10²³ is atoms/mole
