Answer:

speed=5cm/minute

Explanation:

Given at 2:00PM the hermit is at 10cm mark

Also given that the hermit reaches 60cm mark at 2:10PM

Therefore the time elapsed is  10 minutes = 10\times 60=600 seconds

the distance travelled by the hermit is 60-10=50cm=0.5m

We know that

speed=\frac{distane}{time}

speed=\frac{0.5}{600}

speed = 8.3\times 10^{-4} m/sec=5cm/minute

A chemical reaction is at equilibrium. what will be the effect if more of the product is added? question 10 options: the reactio
VashaNatasha [74]

The answer is <span>the reaction will shift to the left (toward the reactants).

Reaction is at equilibrium can be expressed as,
      Reactants </span>⇄ products<span>

<span>After coming to the equilibrium, if one condition is changed, then according to the </span>Le chatelier's Principal,<span> the system will act to maintain the equilibrium by reducing the effect. As an example, if we reduce the pressure, then system acts to increase the pressure to maintain the equilibrium.</span>

<span>Likewise, if we add products into the reaction which is in equilibrium, the system acts to reduce the effect by promoting the backward reaction to produce reactants.</span></span>
