Hemos preparado una disolución de cloruro de cobre (II) en agua disolviendo 12 g de cloruro de cobre (II) en 98 g de agua, de forma que una vez completamente disuelta ocupa un volumen de 100 cm^3. Calcula la concentración en % en peso y en g/l. ¿Qué concentración tendrán 10 cm^3 de esa disolución? Si evaporamos todo el agua que hay en los 10 cm^3 de disolución, ¿cuánto cloruro de cobre (II) se recupera? ¿Qué tendríamos que hacer para que la disolución esté más diluida?

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.

the increase of protons   hope this

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.
