QuestionAI's chemistry problem solver is a middle school chemistry tutoring tool that summarises key chemical reactions and equations in real-time, featuring a robust learning system to empower even those with a weak foundation in chemistry.
You needn't fret over the elemental properties of the periodic table anymore. Here, you can effortlessly access chemical reactions and reaction principles corresponding to each element. Deductive reasoning from microscopic phenomena to discern the original structure of molecules and atoms is a research technique we staunchly champion.
- (c) (i) Ammonium nitrate is another salt of ammonia that can be used as a fertiliser. It can be made from the reaction of ammonia with nitric acid. The balanced equation for the reaction is NH_(3)+HNO_(3)arrow NH_(4)NO_(3) A manufacturer reacts 500g of ammonia with 1000g of nitric acid. Determine the limiting reagent in the reaction. (relative formula masses NH_(3)=17.0,HNO_(3)=63.0) Show your working limiting reagent= __ (ii) A student wants to carry out the same reaction in the laboratory on a smaller scale. The student uses 50cm^3 of a 0.3moldm^-3 solution of ammonia. Calculate the mass of ammonia in the solution in grams. (relative formula mass NH_(3)=17.0) Show your working
- (f) Si_(2)H_(6) reacts with oxygen. The equation for the reaction is: 2Si_(2)H_(6)(g)+7O_(2)(g)arrow 4SiO_(2)(s)+6H_(2)O(g) 30cm^3 of Si_(2)H_(6) is reacted with 150cm^3 (an excess) of oxygen. Calculate the total volume of gases present after the reaction. All volumes of gases are measured at the same temperature and pressure. __
