Answer:
0.89 g of ethane
Explanation:
The balanced reaction equation is
C2H6(g) + 7/2 O2(g) -----------> 2CO2(g) + 3H2O(g)
From this balanced reaction
30g of ethane yields 54g of water
Therefore mass of ethane necessary to obtain 1.61g of water we have:
30 × 1.61/54 = 0.89 g of ethane
The correct answer is option 1. When pellets of solid NaOH are added to water and stirred, the temperature of water increases because chemical energy is converted into heat energy. Dissolution of sodium hydroxide in water is an exothermic process where heat is dissipated.
