Metallic sodium reacts violently with water to form hydrogen gas and sodium hydroxide according to the balanced equation:
2 Na(s) + 2H2O(1) – 2 NaOH(aq) + H2(g)
What is the volume of hydrogen gas produced when 2.500 grams of sodium react
with excess water at 2.10 atm pressure and 23.5°C temperature? (Three sig figs)
Give your answer with three 3 significant figures
Hint: You must first solve for the moles of H2

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates

so what is the problem with your lab report and whats the subject of the lab report? i will you

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
