Guys what the difference between a base and an alkali..another Q why r group 1 metals called alkali metals..

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

Umm gokui what is the answer 4 no.3 b) no.4 c) ii) NAD the last question

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?

equipment lists for practical tests r found in the syllabus in this case 0625 sy 17-19.idea of the paper... if its a new syllabus there r specimen papers for download. U can find the 2 on papacambridge.com
