also measured the mass of the flask with the antacid to get a mass of 123.95 grams. As we move on to the second part of part A my partner and I prepare HCl solution and record its molar concentration at 0.1 ml. We were also able to figure out the volume of the HCl, which turned out to be 25 ml. After we were able to successfully dissolve the antacid my partner and I had to analyze the antacid. After my partner and poured the NaOH solution into the buret we recorded its molar concentration,…

the solution. Finally, the neutralized solution was titrated with 0.1M NaOH till the end point was reached. The volume of 0.1M NaOH used in the final titration was used to calculate DM as follows: DM(%)=(Normality of alkali*Volume of alkali (mL)*31*100)/(mass of sample (mg)) Where normality of alkali was 0.1N, 31represent molar mass of methoxyl group, and volume of alkali is the final volume of NaOH used in the titration. GalA content was calculated according to the formula below:…

overload in fluid volume. If it is less, then either the rate should be increased or colloidal fluids should be started. Biasini et al. (2014) recommends infusing 5% albumin for pediatric burns 40% or greater 48 hours after the injury with a rate of 0.3-0.4 ml/hour multiplied by TBSA percentage of the burn. To prevent confusion in a very stressful situation, the provider should answer the father concisely by informing him that hourly urine output reflects his son’s fluid volume status, and an…

Particle waterjet is similar to the abrasive waterjet; however, particle waterjet uses steel and spherical particles with larger diameter (ranged from 0.5 to 5mm) and smaller particle concentration (ranged from 0.5% to 5% by volume), which is different from the abrasive waterjet [5,6]. Steel particles play an important role in the erosion of rock with a waterjet. Particles erupting from the nozzle at a high speed and frequency impact the rock within extremely short time and…

Crisp brass backgrounds punctuate the second statement of the melody at measure 35. At measure 51, the harmonized trombones and bari sax begin a smooth-flowing bridge. When the trumpets take over the melody at measure 59, the bridge should build in volume and excitement to a peak at measure 65. After the bridge, the saxophones pick up the melody again…

patients are included in this category. To detect early heart failure or heart failure in compensated stages, ventricular filling pressures are evaluated against stroke volume. The ICU nurse may notice elevated cardiac filling pressures. Stroke volume may not be affected in the early stages. As the heart failure progresses, stroke volume is reduced, and tachycardia sets in. However, because of the tachycardia, cardiac output will remain…

thus allowing the individual to train at higher volumes (2,3,5,6). Chrusch et al., reported an average of 31% greater training volume for the Cr group (267,914 kg*reps) compared to the placebo group (227,693 kg*reps) (6). This means that participants in the Cr group are able to train at higher work loads for a longer period of time compared to the placebo group for the given training period (6). The authors attributed this increase in training volume to be responsible for the significant…

Is it possible to predict what it might be? Yes it is possible. As there is 5 mM = 5 mmol/ ml = 5 umol/ml Final volume = 2 ml Therefore = 5 umol/ ml (times both side by 2) = 10 umol/ 2ml From the previous it was found that 5.23 umol are used in 25 minutes. = 10 -5.23 = 4.7 umol/ 2ml (divide both sides by 2) = 2.35 mM After 25 mins the concentration is 2.35…

Aim The aim of this experiment is to discover how different number of pH levels react towards the enzyme catalase, found in beef liver, and will be discovered by the number of oxygen bubbles through the degradation of hydrogen peroxide. Hypothesis The higher the pH level, the more production of oxygen bubbles in the solution. Variables Could affect activity of catalase - Temperature of reactant vessel - Concentration of Hydrogen Peroxide/Catalase - pH level of…
