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.

2 Ammonia, NH_(3) is a simple molecular compound. (a) Hydrogen bonding occurs between molecules of ammonia. Figure 2 shows two molecules of ammonia. H H-N: H-stackrel (N)(H)-H Figure 2 Draw one hydrogen bond between the two molecules shown in Figure 2. You should include the partial charges on the molecules. (b) Ammonia can be reacted with acids to form salts. The salts formed can be used as fertilisers. (i) Ammonia reacts with sulfuric acid to form the salt ammonium sulfate. Identify the correct formula for ammonium sulfate. (2) (1)

Question If you use a carbon dioxide extinguisher in a confined space, there is a risk of what? A. Asphyxiation B. Electric shock C. Hearing damage

Question To stop the chain reaction and extinguish a fire , you need to deprive it of: A. Heat B. Any of these C. Oxygen D. Fuel

A sample of antimony is analysed in a time of flight (TOF)mass spectrometer and is found to contain two isotopes, 121Sb and {}^123Sb After electron impact ionisation all of the ions are accelerated to the same kinetic energy (KE) and then travel through a flight tube that is 1.05 m long. A 121Sb^ast ion takes 5.93times 10^-4s to travel through the flight tube. The kinetic energy of an ion is given by the equation KE=(1)/(2)mv^2 KE=kinetic energy/J m=mass/kg v=speed/ms^-1 Calculate the mass, in kg, of one {}^121Sb^+ ion. Calculate the time taken for a 123Sb^+ ion to travel through the same flight tube. The Avogadro constant, L=6.022times 10^23mol^-1 [5
