Answer:
Increasing the temperature
Explanation:
According to Le Chatelier's principle, "if any of the conditions of a system in equilibrium is changed, the system will adjust itself in order to annul the effect of the change".
Since the forward reaction is exothermic, this suggests that heat is given off in the reaction.
Increasing the temperature will favors the reverse process which is endothermic.
In going from the reactants to the the products, the reaction is deemed exothermic which suggests that it produces heat.
The backward reaction is endothermic i.e it absorbs heat. If the temperature is increased, this process will be favored and more reactants produced. Less of the diiodine pentoxide will form. There is a leftward shift of the equilibrium
There is currently no way to reliably predict when an earthquake will happen, its strength or length. Earthquakes can vary in their magnitude, the size of the earthquake at its source, and length, lasting from seconds to minutes.
Research has shown, that shaking of an earthquake displays a characteristic pattern. After the first tremors start, building up in intensity, a peak is reached, followed by a fading shaking. Large and small earthquakes start the same way, but there is no way to say when the peak, the maximal magnitude of the quake, is reached.
Answer:
<h3>The answer is 0.03 moles</h3>
Explanation:
To find the number of moles given the number of entities we use the formula
![n = \frac{N}{L} \\](https://tex.z-dn.net/?f=n%20%3D%20%20%5Cfrac%7BN%7D%7BL%7D%20%5C%5C)
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question
N = 2 × 10²² molecules of water
We have
![n = \frac{2 \times {10}^{22} }{6.02 \times {10}^{23} } \\ = 0.033222591...](https://tex.z-dn.net/?f=n%20%3D%20%20%5Cfrac%7B2%20%5Ctimes%20%20%7B10%7D%5E%7B22%7D%20%7D%7B6.02%20%5Ctimes%20%20%7B10%7D%5E%7B23%7D%20%7D%20%20%5C%5C%20%20%3D%200.033222591...)
We have the final answer as
<h3>0.03 moles</h3>
