NA(OH)2 is actually sodium hydroxide. The sodium (NA) cation carries a +2 charge, and the hydroxide (OH) anion carries a -1 charge. To balance the equation you must have 2 hydroxide ions to make the anionic charge total -2 to match the cationic +2 charge. It is used to make soaps, cleaners, and hydrogen gas in an aqueous solution when exposed to electrical current. It is a highly corrosive base and should be handled with caution.
You just take your table salt which is nacl . 2nacl+h2o-- naoh2+cl2
No because you have an extra H. Sodium hydroxide is NaOH.
The conjugate acid of NaOH is NaOH2+ (sodium hydroxide in its protonated form). When NaOH accepts a proton, it forms the conjugate acid NaOH2+ and a hydroxide ion (OH-).
The reaction between HCl (hydrochloric acid) and Al (aluminum) in water produces hydrogen gas and aluminum chloride. The balanced equation is: 2Al(s) + 6HCl(aq) -> 2AlCl3(aq) + 3H2(g)
It's may have been plated for use in jewelry, or more likely was used in a high-school chemistry experiment. I forget the details but there's a compound (NaOH2 ?) that reacts with copper to turn it a goldish color. Either way it's not worth anything as a rarity but it makes an interesting conversation piece.
Not always. The naming of acids and bases does not directly indicate their strength. Strong acids or bases tend to dissociate completely in water, while weak acids or bases only partially dissociate. Factors such as chemical structure and equilibrium constants determine the strength of an acid or base rather than its name.
To find the number of moles in 80.00g of NaOH, you need to divide the mass in grams by the molar mass of NaOH. The molar mass of NaOH is 40 g/mol (sodium: 23g/mol, oxygen: 16g/mol, hydrogen: 1g/mol). Therefore, 80.00g / 40 g/mol = 2 moles of NaOH.
The balanced equation for the reaction between calcium nitrate (Ca(NO3)2) and sodium hydroxide (NaOH) is: Ca(NO3)2 + 2 NaOH → Ca(OH)2 + 2 NaNO3. This reaction forms calcium hydroxide (Ca(OH)2) and sodium nitrate (NaNO3).
