8.4 Application of Kinematics of Linear Motion Format for Additional Mathematics Exam based on the Malaysia Certificate of Education is as follows: Paper 1 (Duration: 2 Hours): Questions are categorised into Sections A and B and are tested based on the student's knowledge to grasp the concepts and formulae learned during their 2 years of learning.
Glucose (C 6 H 12 O 6), ribose (C 5 H 10 O 5), Acetic acid (C 2 H 4 O 2), and formaldehyde (CH 2 O) all have different molecular formulas but the same empirical formula: CH 2 O.This is the actual molecular formula for formaldehyde, but acetic acid has double the number of atoms, ribose has five times the number of atoms, and glucose has six times the number of atoms.
Hargreaves: 4 NaCl + 2 SO 2 + O 2 + 2 H 2 O → 4 HCl + 2 Na 2 SO 4. The second major production of sodium sulfate are the processes where surplus sodium hydroxide is neutralised by sulfuric acid to obtain sulfate (SO 2− 4) by using copper sulfate (CuSO 4) (as historically applied on a large scale in the production of rayon by using copper(II ...
C 4 CoF 3 O 4 Si: trifluorosilylcobalt tetracarbonyl: 15693-79-5 C 4 Dy: dysprosium tetracarbide: 12543-88-3 C 4 F 4 O 3: tetrafluorosuccinic anhydride: 699-30-9 C 4 F 6 O: hexafluorocyclobutanone: 699-35-4 C 4 F 8: octafluorocyclobutane: 115-25-3 C 4 F 10 O 2 S: nonafluorobutanesulfonyl fluoride: 375-72-4 C 4 FeI 2 O 4: iron tetracarbonyl ...
Lead tetrachloride, also known as lead(IV) chloride, has the molecular formula PbCl 4. It is a yellow, oily liquid which is stable below 0 °C, and decomposes at 50 °C. [2] It has a tetrahedral configuration, with lead as the central atom. The Pb–Cl covalent bonds have been measured to be 247 pm and the bond energy is 243 kJ⋅mol −1. [4]
Ammonium iron(II) sulfate, or Mohr's salt, is the inorganic compound with the formula (NH 4) 2 SO 4 ·Fe(SO 4)·6H 2 O. Containing two different cations, Fe 2+ and NH + 4, it is classified as a double salt of ferrous sulfate and ammonium sulfate. It is a common laboratory reagent because it is readily crystallized, and crystals resist oxidation ...
Titanium(IV) acetate or titanium tetraacetate is a coordination complex and white chloroform soluble solid with the formula Ti(C 2 H 3 O 2) 4. [1] Crystallographic evidence has not been presented. It can be prepared by reacting tetramethyltitanium with acetic acid .
A chemical formula used for a series of compounds that differ from each other by a constant unit is called a general formula. It generates a homologous series of chemical formulae. For example, alcohols may be represented by the formula C n H 2n + 1 OH (n ≥ 1), giving the homologs methanol, ethanol, propanol for 1 ≤ n ≤ 3.
