The reaction 2Na(s) + 2H2O(l) → 2NaOH(s) + H2(g) is a single displacement reaction, where sodium (Na) displaces hydrogen from water (H2O). This is also an exothermic reaction, as it releases energy in the form of heat when sodium reacts with water. The reaction produces sodium hydroxide (NaOH) and hydrogen gas (H2).
What else can I help you with?
which of the following equations is balanced?
2na+s-2nas
2Nas Cl2g 2NaCls what is described in this equation?
This equation represents the reaction between sodium (Na) and chlorine (Cl2) gas to form sodium chloride (NaCl), which is commonly known as table salt. The reaction is a combination reaction where two reactants combine to form a single product.
Is 2Na S 2NaS a balanced equation?
No, the equation is not balanced. It should be written as 2Na + S → 2NaS to show that two sodium atoms combine with one sulfur atom to form two sodium sulfide molecules.
Is 2Na plus S and 2NaS considered a balanced equation?
Consider firstly if there are equal numbers of atoms of each element on either side of the reaction. No, there aren't: there are too many sodium, chloride ions and hydrogen atoms on the reactant side, so the equation is not balanced.
Which one of the following chemical equations is balanced a 2naci h2so4 hcl naso4 b nh3 h2o 2nh4oh c koh h2so4 khso4 h2o d 2na s 2nas?

Why is sodium stored in kerosene and not water?
Because it will react violently in water producing hydrogen gas in a highly exothermic reaction which often causes ignition of the hydrogen gas liberated: 2Nas + 2H2Ol --> H2,g + 2(NaOH)aq The kerosene used for storage must be importantly water free, or anhydrous, otherwise this reaction will also occur but more slowly. This is often exploited to remove trace water from organic solvents for chemical synthesis.
