How many grams of sodium metal are needed to react completely with 25.8 liters of chlorine gas at 293 kelvin and 1.30 atmospheres? ideal gas law after stoichiometry i don't need the answer don't give it just explain how to solve it.

Hello!

To answer this question you need to first write the chemical equation for this reaction:

2Na(s) + Cl₂ → 2NaCl

Now, you know that to react 1 mol of Chlorine gas you'll need 2 moles of sodium, this can be written as follows:

(1)

So, the last step in solving this problem is to know how many moles of Chlorine you have. For that, you'll use the Ideal Gas Law which states that:



(2)

Where P is pressure, V is volume, n is the amount of the gas in moles, R is the Constant of the Ideal Gases and T is the temperature. 

The final step is replacing the expression (2) in (1) and you're good to go!

I won't give the answer to this problem, just leave the equation for you to replace the values. 

Answer : option c) heat is released during the process.explanation :

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.

The answer is nitrogen-containing bases
