this is lithium ion with a +1 charge
The balanced equation for the neutralisation reaction is as follows
2HNO₃ + Ba(OH)₂ ---> Ba(NO₃)₂ + 2H₂O
stoichiometry of HNO₃ to Ba(OH)₂ is 2:1
number of Ba(OH)₂ mol present - 0.108 mol
1 mol of Ba(OH)₂ neutralises 2 mol of Ba(OH)₂
therefore 0.108 mol of Ba(OH)₂ neutralises - 2 x 0.108 mol = 0.216 mol of HNO₃
Answer:
mp -5; bp 30
Explanation:
That will be a liquid at room temperature, and it will evaporate quite quickly. Room temperature is generally considered 20 degrees Celsius. Choice B melts from a solid to a liquid at -5 degrees, so it's a liquid at room temperature as long as the boiling point is higher than 20 degrees.
Answer:
Neutralization reaction is a reaction between an acid and a base. In general, when the reaction is performed in aqueous media, produce water and salt.
Explanation:
Arrhenius defined a base as a substance who forms OH- ions. Bronsted, define it as an proton acceptor.
On the other hand Arrhenius defined an acid as a substance who form H+ ions. Breonsted define it as proton donor.
Acid + base ----> salt + water
A salt is an ionic compund formed by a cation and anion. All salts are strong electrolytes. An example of a neutralization reaction is:
HCl (ac) + NaOH (ac) -------> NaCl (ac) + H2O(l)
Nevertheless, because the acid and the base are strong electrolytes, in water they are completely dissolved actually look like this:
H+ (ac) + Cl(ac) + Na+(ac) + OH-(ac) ------> Na+(ac) + Cl-(ac) + H2O(l)
