According to the following reaction, what volume in milliliters of 0.244M KCl(aq) solution is required to react exactly with 50.

Elodia [21]

Answer:

There is 86.1 mL of KCl needed

Explanation:

Step 1: Data given

Molarity of KCl = 0.244 M

Volume of a 0.210 M Pb(NO3)2 = 50.0 mL = 0.05 L

Step 2: The balanced equation

2KCl(aq) + Pb(NO3)2(aq) -> PbCl2(s) + 2KNO3(aq)

Step 3: Calculate moles Pb(NO3)2

moles Pb(NO3)2 =molarity * volume

moles Pb(NO3)2 = 0.210 M * 0.05 L

moles Pb(NO3)2 = 0.0105 moles

Step 4: Calculate moles of KCl

For 1 mole of Pb(NO3)2 we need 2 moles of KCl

moles KCl required = 0.0105 * 2 =0.0210 moles

Step 5: Calculate volume of KCl

Volume = moles KCl / molarity KCl

V = 0.0210 moles / 0.244 M=0.0861 L = 86.1 mL

There is 86.1 mL of KCl needed

water absorbs and releases large amounts of heat before its temperature changes because water has a high

barxatty [35]

Waters high heat capacity is a property focused by hydrogen bonding among water molecules.When heat is absorbed,hydrogen bonds are broken and water molecules can move freely.When the temperature of water decreases, the hydrogen bonds are formed and release a considerable amount of energy

Process in which water vapor turns to liquid

Rudiy27

In the amtmosphere this water vapor cools and turns back to liquid for forming clouds
this process is called condensation. When it cant hold on much longer it will turn into rain or snow.

The value of h for the reaction below is -73 kj how many kj of heat are released

jarptica [38.1K]

If the value of H is positive, it means you have to add that much heat to complete the reaction. If H is negative, it means that much heat is released during the chemical process. Because it is -73 kJ, 73 kJ of heat are released in the reaction.
