Propose a method for determining the specific heat for a metal like sodium which reacts violently with water.
nalin [4]
You can put a known amount sodium into some sort of time release mechanism such as a pill made from soluble material.  Then you can place the sodium into a calorimeter with a known mass of water and record the temperature change the water undergoes during the reaction.  Then you can use the equation q(water)=m(water)c(water)ΔT to find the amount of heat absorbed by the water.  since the amount of heat absorbed by the water is the amount of heat released from the sodium, q(sodium)=-q(water).  Than you can use the equation q(sodium)=m(sodium)c(sodium)ΔT and solve for c(sodium)

I hope this helps and feel free to ask about anything that was unclear in the comments.

Which equation is used to help form the combined gas law? mc009-1. Jpg mc009-2. Jpg mc009-3. Jpg mc009-4. Jpg.
Luba_88 [7]

The combined gas law equation has been \dfrac{P_1V_1}{T_1}=\dfrac{P_2V_2}{T_2}.

The combined gas law has been assigned to the ideal gas. It has been stating that ideal gas are having negligible inter-molecular attraction and collision resulting in the absence of pressure and volume from the particles.

In an ideal gas the equation has been given as:

PV=nRT

Where, <em>P </em>has been the pressure of the gas

<em>V </em>has been the volume of the gas

<em>n </em>has been the moles of the gas

<em>R </em>has been a constant

<em>T </em>has been the temperature of the gas

The combined gas law has been given as the change in the pressure, and volume for a gas. It has been given as:

\dfrac{P_1V_1}{T_1}=\dfrac{P_2V_2}{T_2}

For more information about combined gas law, refer to the link:
