Ok , firstly , alkalis are bases which dissolve in water , while bases do not . G-1 metals are called alkali metals bcz these metals react with acids only , so behave similarly to alkalis

no 3 b i think the mole question i think 1440 cm3 4c(ii) platinum reason: transition element last question i think because they are different,not sure really about the last one

Yeah I remembered the platinum one after I sent the message no.3 b) is for reaction of mgco³ and h²no³ I think water and co² r produced but in not sure same with the last one

its mgco3 with hno3 not h2no3 i think

Has anyone seen the equipment list for Bio Paper 31?
Or have a rough idea what the paper may have?
