**Text Transcription for Educational Website**### Reactions and Calculations with Hydrates**1. Aluminum Chloride Hexahydrate**\[ \text{Aluminum Chloride Hexahydrate: } \text{AlCl}_3 \cdot 6\text{H}_2\text{O} \]- **AlCl₃ Molecular Weight:** 133.34 g/mol- **AlCl₃·6H₂O Molecular Weight Calculation:** \[ 133.34 + 6(18.02) = 241.46 \, \text{g/mol} \]- **Percentage of Water (Th\%):** \[ \text{Th\%} = \left( \frac{6(18.02)}{241.46} \right) \times 100\% = 44.78\% \]**2. Reaction of Iron(II) Sulfate**- **Reaction:** \[ \text{FeSO}_4(s) \rightarrow \text{FeO}(s) + \text{SO}_3(g) \]- If you heat a sample of FeSO₄·6H₂O and this reaction occurs along with dehydration, the experimental percent water will likely decrease since SO₃ is released as a gas, indicating additional weight loss beyond water alone.**3. Determining Water Content in Calcium Chloride Hydrate**- **Given:** 8.416 g sample of CaCl₂·xH₂O; 5.624 g remains after heating.- **Mass of H₂O lost:** \[ 8.416 \, \text{g} - 5.624 \, \text{g} = 2.792 \, \text{g} \]- **Moles of H₂O:** \[ 2.792 \, \text{g} \times \left( \frac{1 \, \text{mol}}{18.02 \, \text{g}} \right) = 0.1549 \, \text{mol} \]- **Moles of CaCl₂:** \[ 5.624 \, \text{g} \times \left( \frac{1 \, \text{mol}}{110.98 \, \text{

Distinguish between water quality and hydrochemistry.
Sodium hydrogen carbonate (NaHCO,), also known as sodium bicarbonate or "baking soda", can be used to relieve acid indigestion. Acid indigestion is the burning sensation you get in your stomach when it contains too much hydrochloric acid (HCI) , which the stomach secretes to help digest food. Drinking a glass of water containing dissolved NaHCO, neutralizes excess HCl through this reaction: HCl(aq) + NaHCO;(aq) → NaCl(aq) + H,O(1) + CO,(g) The CO, gas produced is what makes you burp after drinking the solution. Suppose the fluid in the stomach of a man suffering from indigestion can be considered to be 100. mL of a 0.048 M HCI solution. What mass of NaHCO, would he need to ingest to neutralize this much HCl ? Be sure your answer has the correct number of significant digits. x10
Suppose you want to measure the amount of glucose in a can of soda. You can use the data generated in this experiment to help you, but what other data would you need to collect in order to measure the concentration of glucose in the soda? In other words, what additional experimental step(s) would you perform? B I U Ꭶ X X, 14▾ A In order to measure the amount of glucose in a can of soda, one would need to prepare a series of standard solutions w/ an unknown concentrations of glucose using the 0.3M of glucose sol'n and DI water. Therefore, the glucose oxidase assay would be performed on each standard sol'n and the result values would also be measured by a spectrophotometer. A standard curve may then be plotted by absorbances and the unknown concentration of glucose. It may also be necessary to adjust the pH of the soda can sample to preform additional steps.

The reaction A(aq) + B(aq) C(aq) + D(aq) has a ΔHrxn = -85 kJ/mol. This reaction is endorthermic or exothermic . If the temperature of the reaction mixture is increased, equilibrium will shift towards the reactans or products. This change will decrease or increase the concentration of the reactants and K will increase or deacrease
