Has to be correct
The forces between particles are called intermolecular forces. A strong intermolecular force means that the particles are tightly paced and is associated with the solid phase. Moderate intermolecular force is associated with the liquid state and little to no intermolecular force is associated with the gaseous state. Temperature has a direct effect on the state of matter in which the substance exists has. Generally speaking, a rise in tempreature changes a substance from the solid to liquid phase and from liquid to gaseus phase. The reverse is true, if the temperature lowers then the substance will go from gas to liquid and liquid to solid. It is important to not that temperature affects intermolecular forces. As the temperature increases then the individual particles become excited and gain enough energy to over the intermolecular forces and so the particles seperate from each other.
Answer:
21 mL of KOH
Explanation:
We have to start with the <u>reaction</u> between HCl and KOH:
Now, using the <u>molarity equation</u> we can <u>find the moles</u> of HCl, (we have to keep in mind that we have to use the <u>volume in L</u>, 21 mL=0.021 L)
Now, we can convert from mol of HCl to mol of KOH using the <u>molar ratio</u> of the balanced reaction. (1 mol HCl= 1 mol KOH)
Finally, we have to calculate the <u>volume of KOH</u> using the molarity equation again:
When we <u>convert </u>this value to mL units we will get:
<u>We will need 21 mL of KOH at the equivalence point</u>.
