Moles of HBr need to react = 5 moles
As the molar ratio is 1 is to 2 among them
Moles=molarity x volume
5=2.25 x volume
volume=2.22 litres of HBr required for this reaction
ANSWER IS 2.22 LITRES
b. acid is the correct answer @jayxboof all social media
acid : acids are those which accepts an electron-pairs.
base : bases are those which donates ab electron-pairs.
alkali : it is a base that dissolves in water. it is basically a base and the ph greater than 7.
hydroxide ion : it is a poly-atomic ion which is negatively charged.
it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.
an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
