In combined science A, science is delivered in the three traditional parts of biology, chemistry and physics. Like AQA's trilogy, each science part is broken into topics in combined science A's specification document , but unlike AQA combined science, practicals are suggested rather than specified, although practicals are still compulsory (the ...
The O grade was equivalent to a GCE Ordinary Level pass which indicated a performance equivalent to the lowest pass grade at Ordinary Level.. Over time, the validity of this system was questioned because, rather than reflecting a standard, norm referencing simply maintained a specific proportion of candidates at each grade, which in small cohorts was subject to statistical fluctuations in ...

Devarda's alloy (Copper/Aluminium/Zinc) is a reducing agent.When reacted with nitrate in sodium hydroxide solution, ammonia is liberated. The ammonia formed may be detected by its characteristic odor, and by damp red litmus paper's turning blue, signalling that it is an alkali — very few gases other than ammonia evolved from wet chemistry are alkaline.
