Consider the titration curve below

if an erlenmeyer flask that is used in this titration contains 40.0 ml of 0.10 m hcl, how many moles of hydrogen ions are present at the point that is labeled a on the graph?
option a) 0.0025
option b) 0.0040
option c) 40.0
option d) 4000

i think A because .10 divided by 40 would be .0025

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.

b) mutualism

hope this : )
