Cooking energy to our cars liquid fuels
The enthalpy of the creation of Methanol is negative. This means heat is released when the reaction proceeds. You would want to use a low temperature.
<u>Answer</u>: + 4 m/s
<u>Working Ou</u>t:
V = Δ x ÷ Δ t ;where V = velocity, Δ x = displacement, Δ t = change in time
V = Δ x ÷ Δ t
V = (12 m east) ÷ 3.0 s
V = 4 m/s to the east OR V = + 4 m/s
∴ The velocity of the wave is + 4 m/s
<span>pH=pKa + log [salt] / [acid] = 9.31 + log 0.15 / 0.20 = 9.31 - 0.125 pH = 9.19
Hope this helped :)</span>
