If you place 2 moles of NaCL in a beaker and then add enough water to have a final volume of 0.5 liters, what is the molarity of

Answer:

The molarity of the solution is 4M

Explanation:

Molarity is defined as the amount of moles of solute present in one liter of solution. So the molarity of any solution can be found by dividing the moles of solute between the volume in liters of the solution.

For this case we have:

M=\frac{2\:moles\:NaCl}{0.5\:L\:solution} =4M

Write the complete ionic equation and the Net ionic equation for: K2C2O4(aq)+Pb(OH)2(aq) -> 2KOH(aq)+PbC2O4(s)
Kipish [7]
Molecular chemical equation: 
K₂C₂O₄(aq)+Pb(OH)₂(aq) → 2KOH(aq) + PbC₂O₄<span>(s).
Ionic equation:
2K</span>⁺(aq) + C₂O₄²⁻(aq) + Pb²⁺(aq) + 2OH⁻(aq) → 2K⁺(aq) +2OH⁻(aq)+PbC₂O₄(s)
Net ionic eqation:
C₂O₄²⁻(aq) + Pb²⁺(aq) → PbC₂O₄(s).
s is solid, do not dissolve in water, potassiom hydroxide is trong base and dissolves in water.

A food provides enough energy to raise the temperature of 2000 grams of water by 10°c. how many kilocalories does it contain?
Musya8 [376]

A food provides enough energy to raise the temperature of 2000 grams of water by 10°c contains 20 KCa.

1 Calorie is the amount of heat needed to elevate one gram of water to one degree Celsius temperature at one atmosphere of pressure.

The term "kilocalorie" is used to describe the amount of energy needed to increase 1 L of water's temperature by one degree Celsius at sea level.

Given

Mass of water (m) = 2000 g
Temp raise (ΔT) = 10°C

Heat capacity of water (C) =  1 calorie/g-C

Formula used

Heat (ΔH) = m × C × ΔT

                = 2000 × 10 = 20000 C

In Kilo calories

20000 C = 20000/1000 = 20 KCa

Hence, a food provides enough energy to raise the temperature of 2000 grams of water by 10°c contains 20 KCa.
