<span>F = ma
</span>Ff = μ*Fn
<span>Fn = Fw
</span>Fw = mg
<span>So we have: </span>
<span>Ff = μmg </span>
<span>And </span>
<span>Ff = ma </span>
<span>So... </span>
<span>μmg = ma </span><span> </span>
<span>μg = a </span>
<span>And we can solve for the acceleration: </span>
<span>(0.15)(9.81 m/s²) = a </span>
<span>a = 1.47 m/s² </span>

Answer:
28 moles of X.
Explanation:
Let's consider the complete combustion of ethanol.
C₂H₆O(l) + 3 O₂(g) ⇒ 2 CO₂(g) + 3 H₂O(l)
When 1 mole of ethanol burns it releases 1370 kJ, that is, the enthalpy of combustion is -1370 kJ/mol. If the energy released by one mole of etanol were used to syntesize the compound X, it would take 45.9 kJ to form 1 mole of X, that is, the enthalpy of formation is -49.5 kJ/mol. Then,
