Concept explainers

States of Matter

The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).

Chemical Reactions and Equations

When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.

There's 1 drink (and you are asked to determine the glucose concentration in the drink in the units of g/100mL. (Why these units? Well, once you have the concentrations in g/100mL you will be able to compare your values with the nutritional values given on the drink bottles’ labels). The sample of the drink was diluted 1/100 (i.e. by a factor of 100). This was an essential step in the method because, without it, the machine used to analyse the glucose concentration (spectrophotometer) would have given an error as the concentration would have been too high for accurate detection. What this means for you is that the dilution factor will need to be taken into consideration in your calculations (remember the aim is to calculate the concentration in the original drink and not in the diluted drink). You measured the concentration of their diluted drink using the spectrophotometer and their results were provided to them in the units mM (millimolar). Glucose Concentration in mM of drink =…

A mixture of ethanol (ethyl alcohol) and water contains 40.0% water by mass.(a) Assuming volume additivity of the components, estimate the specific gravity of themixture at 20°C. What volume (in liters) of this mixture is required to provide 150 mol ofethanol?(b) Repeat Part (a) with the additional information that the specific gravity of the mixture at20°C is 0.89045 (making it unnecessary to assume volume additivity). What percentage errorresults from the volume-additivity assumption?
Hot mix asphalt (HMA) is commonly used in the construction of roadways in the United States at a rateestimated to be 500,000,000 tons/year. A typical upper layer (there may be as many as 5 layers ofdifferent thicknesses and compositions) of a high-volume highway is composed of crushed stone (alsoknown as crushed aggregate) and asphalt binder and is approximately 1.25 inches thick. The stone,which has a specific gravity of about 2.7, is mixed with asphalt binder (SG = 1.03) to form the HMAwith a composition of approximately 95 wt% aggregate and 5% asphalt. What is the volume ft3 of asphalt binder and weight (tons) of HMA required for the top layer of a 15-mile segment of interstatehighway with 5 lanes, each of which has a width of 12 ft?
A core sample is saturated with an oil (?o = 35oAPI), gas and water. The initial weight of the sample is 224.14 g. After the gas is displaced by water (?w = 1 g/cm3 ), the weight is increased to 225.90 g. The sample is the placed in a Soxhlet distillation apparatus, and 4.4 cm3 water is extracted. After drying the core sample, the weight is now 209.75 g. The sample bulk volume, 95 cm3 is measured in a mercury pycnometer. Find the porosity, water saturation, oil saturation, gas saturation and lithology of the core sample.
A given soil sample is subjected for proximate analysis - specifically moisture content and analysis of inorganic matter (or ash) content. A cleaned and tared crucible is weighed in an analytical balance and found to be 4.5015 grams . The soil sample is weighed-in and the crucible, together with the plant sample, measured a total of 6.2525 grams. The set-up is then placed in an oven and dried to 105 degrees Celsius for at least two hours. The setup is cooled to room temperature in a dessicator and then measured to a constant weight of 5.9775 grams. Afterwards, the setup is placed inside the muffle furnace and ignited to 720 degrees Celsius for at least an hour. The set-up is cooled to room temperature again inside the dessicator and then measured to the constant weight of 4.9375 grams. (A) What is the percent moisture in the plant sample?
