A slug travels the length of a log in 2 hours. If the slug's average speed is 1.5 cm / minute how long is the log

The length of the log is 180 cm

Explanation:

From the question given above, the following data were obtained:

Time = 2 hours

Speed = 1.5 cm/min

Distance =?

Next, we shall convert 2 hours to minutes. This can be obtained as follow:

1 h = 60 mins

Therefore,

2 h = 2 × 60

2 h = 120 mins

Finally, we shall determine the Lenght of the log. This can be obtained as follow:

Time = 120 mins

Speed = 1.5 cm/min

Distance =?

Speed = distance / time

15 = distance / 120

Cross multiply

Distance = 1.5 × 120

Distance = 180 cm

Therefore, the length of the log is 180 cm

answer: the enthalpy of the overall chemical reaction is +87.88 kj or +88 kj.

according to hess's law, the overall enthalpy of a reaction is the difference between the sum of enthalpy values of all the products and the sum of enthalpy values of all the reactants.

δh(reaction) = ∑nδh(products) - ∑nδh(reactants)

δh(reaction) = [δh +δh] - [δh]

δh(reaction) = [1(-287.02) + 1(0) ] - [1(-374.9)] kj = +87.88 kj

here, δh (pcl3) = -287.02 kj, δh(cl2) = 0, δh(pcl5) = -374.9 kj

therefore, enthalpy of the overall reaction is +87.88 kj or +88 kj.
