2Na + 2H2O--->H2+ 2NaOH
Hydrogen gas is diatomic, therefore it requires a subscript of 2.
Zn(s) + 2HCl(aq) -------> ZnCl2(aq) + H2(g)
Calcium + water gives hydydrogen gas plus Calcium ions in solution and hydroxide ions in solution.
Water and sodium metal are reactants to produce sodium hydroxide and hydrogen gas. H2O + Na ==> NaOH + H2 !! VERY dangerous !! Sodium Metal and Water
Reactants: sodium (metal, Na) and water (H2O) Products: Hydrogen (gas, H2) and sodium hydroxide (NaOH)
2H2O22H2O + O2(g)
2 LiOH + CO2 = H2O + Li2CO3
No, actually they produce hydrosonium ions in an aqueous medium.
hydroxide atoms
When sodium and water react, they will produce aqueous sodium hydroxide and hydrogen gas. Here's the balanced equation for that reaction: 2Na + 2H2O --> 2NaOH + H2 This reaction is violently exothermic and should be done under very safe and controlled conditions. The hydrogen gas will likely ignite, which itself is a different reaction: 2H2 + O2 --> 2H2O
It produces soap.
This equation [not technically "formula"] is 2 Li + 2 H2O -> 2 LiOH + H2.
It produces zinc hydroxide and hydrogen.
If you mean just potassium hydroxide or its aqueous solution, then no, because their are no chlorine atoms present. The only elements present are potassium, hydrogen and oxygen. Molten KOH produces potassium at the cathode and oxygen at the anode, and the solution gives hydrogen at the cathode and oxygen at the anode.
A salt
Calcium and Hydroxide (1 Oxygen atom+1 Hydrogen atom)
Because ammonia gas (NH3) reacts with water (H2O) to produce the aqueous solution ammonium hydroxide. This reaction produces hydroxide ions in the solution, thus making it an Arrhenius base.
According to Arrhenius, acids produce a proton in aqueous solution, and bases produce a hydroxide ion in aqueous solution. Hydrochloric acid is an Arrhenius acid because it gives up its proton as it dissolves in water. Sodium hydroxide is an Arrhenius base because it gives up its hydroxide as it dissolves in water.
