Analysis of a Carbonate-Bicarbonate Mixture Manalo‚ Ma. Cristina Joyce B. Department of Chemical Engineering‚ Faculty of Engineering University of Santo Tomas Espana‚ Manila A. Abstract Crude sodium bicarbonate or commonly known as soda ash may contain amounts of impurities like chlorides and hydroxides. The total acid neutralizing capacity of a soda ash sample‚ its alkalinity value‚ was stated in terms of mass of sodium carbonate. In doing so‚ any sodium hydrogen carbonate present in the

Figure 12.4: e – log sv’ plot 5. Recompression Index. Determine it from the plot of voids ratio (e) vs log σ plot as (Figure 12.4 or 12.5) 12.11 6. Coefficient of compressibility. It is calculated as follows av = 0.435 Cc/Avg. pressure for the increment 12.12 where Cc = compression index av = Coefficient of compressibility

Research how a basic roller coaster works. What determines how high your loops or hills can be? What determines how many features you can have in one roller coaster? Something that determines how high you’re loops and hills go is how much kinetic energy the coaster has before going into those loops and hills. If a coaster does not have enough kinetic energy to go up and around a loop or up a hill‚ then it will get stuck. Also‚ if the coaster carts don’t have enough space between them‚ they could

will become positively charged. Electric charges can be characterized by repulsion between two positive charges or two negative charges‚ and can also be attraction between a positive charge and a negative charge. In this experiment‚ we were able to determine the presence of electrostatic charges with the use of an electroscope. It is performed by using three different kinds of rod (plastic‚ glass‚ and PVC)‚ each rubbed with silk cloth‚ flannel cloth‚ and fur cloth. The observations we have done brought

What determines the perceived brightness of objects? Luminance is a physical and objective measure of the intensity of light. The sensation elicited by different luminances is called brightness. However brightness is a subjective measure as it is the perceived amount of light emanating from an object. It may seem logical to expect that luminance and brightness are directly proportional and that two objects that reflect the same amount of physical light into the eye will look the same brightness

The reaction order‚ based on the rate law‚ was first order with respect to crystal violet and second order with respect to OH-. The rate law was as follows: Rate law = k [CV]1[OH-]1 where k equaled 2.61. In order to determine the reaction order with respect to crystal violet‚ the graph that described the relationship between ln[CV] and time (seconds) was Figure 2. Not only did Figure 2 generate a more linear relationship‚ but it had the highest R2 value of 0.992 than ([CV] versus time) and ([1/CV]

OUR ATTITUDE DETERMINES YOUR FUTURE DO NOT PROCASTINATE! TIME is money and TIME does not wait for anybody. If you sit and wait‚ nobody can help you and nothing happens. You will still be what you are‚ 3 or more years from now. You will be in the same situation‚ doing what you are doing now or worst‚ not doing anything at all; No career advancement; No self development; Lack of work experience; No improvement in income; No appropriate qualification; and possibly even out of job!

ATTITUDE DETERMINES ONE’S ALTITUDE IN LIFE Attitudes Defined Attitudes are the established ways of responding to people and situations that we have learned‚ based on the beliefs‚ values and assumptions we hold. Attitudes become manifest through your behavior. Attitude Drives Behavior Attitudes drive behavior. Your body language is a result of your mental attitude. By choosing your attitude you get in that mood and send out a message that everyone understands‚ consciously or unconsciously. "Almost
