Physical and Chemical Changes Say you are presented with two beakers‚ beaker A and beaker B‚ each containing a white‚ powdery compound. * a. From your initial observations‚ you suspect that the two beakers contain the same compound. Describe‚ in general terms‚ some experiments in a laboratory that you could do to help prove or disprove that the beakers contain the same compound. You may try some of the followings: * Dissolving in water * Dissolving in different chemical solution

Example: 4308 (4 sig. figs.) 3. Trailing zeros to the right of a decimal point are significant. Example: 4.00 (3 sig. figs.) 4. Leading zeros are not significant. Example: 0.000045 (2 sig. figs.) 5. Measured values that have trailing zeros only to the left of the decimal point are ambiguous and should be expressed in scientific notation. We must take note that the chemistry textbook (Silberberg 6e) states that placing a decimal point to the right of some trailing zeros (example: 300.) will

Contents We have seen an example of use of finite automata in describing the operation of a simplified version of vending machine. Many other systems operating in practice can also be modeled by finite automata such as control circuits of computers‚ computer network communication protocols‚ lexical analysers for compilers etc. Many of those systems fall into the class of systems called reactive system. A reactive system is a system that changes its actions‚ outputs and conditions/status in response

of a digit beyond the decimal point is a significant figure. The number 14.720 consists of five significant figures. (Note the zero would not be necessary to set the decimal point‚ thus it is significant). A zero is not significant if it merely fixes the decimal point. The number 0.031 contains two significant figures‚ the zero sets the decimal point and is not significant. In the number 1200 the zeros may or may not be significant.
