CHEMISTRY CLASS 9 CLASS WORK Chemical formulae and equations Derivation of formulae (key points) Chemical Formula Definition: An expression which states the number and type of atoms present in a molecule of a substance. Stoichiometry is the calculation of relative quantities of reactants and products in chemical reactions. In physical chemistry, the rate of reactions in . This is a requirement the equation must satisfy to be consistent with the law of conservation of matter. Symbol . The answer will appear below; Always use the upper case for the first character in the element name and the lower case for the second character. eg. Chemical equations can be written using either words or chemical symbols.With chemical equations, we often indicate the state symbols after each molecule or element in the symbol equations to indicate whether they are in solid, liquid, aqueous or gaseous form.For example, a displacement reaction between copper sulfate and magnesium, can be shown as follows: The relationship equation between pressure and temperature in Gay Lussac Law can be expressed in the graph as follows: 4. eg: we use (g) for gas, (l) for liquid, (s) for solid and (aq) for aqueous. Chemical Formulas A formula is a representation of the composition of a compound. This chemistry video tutorial explains how to write net ionic equations. Avogadro Constant . Ca. STEP2: Write known to the left and unknown to the right. reactants → products. The concentration of the starting solution was 4M, and the concentration of the ending solution was 2M. 1.5: CHEMICAL FORMULAE AND EQUATIONS. The formula is as follows: V 2 / V 1 = M 1 / M 2. STEP4: Convert moles into mass. Question 5 Translate the following statements into chemical equations and then balance them. Stoichiometry is founded on the law of conservation of mass where the total mass of the reactants equals the total mass of the products leading to the insight that the relations among .
