Answer questions 2, 3 and 4 ### Chemistry Problems and Solutions#### 2. Balancing Chemical EquationsBalance the chemical equation for the following reaction:\[ \text{C}_4\text{H}_9\text{OH} + \text{O}_2 \rightarrow \text{CO}_2 + \text{H}_2\text{O} \]The equation is initially unbalanced.**Tasks:**- **a)** Set up the mole ratio of $\text{O}_2$ to $\text{C}_4\text{H}_9\text{OH}$.- **b)** Set up the mole ratio of $\text{CO}_2$ to $\text{O}_2$.#### 3. Moles of Aluminum OxideHow many moles of aluminum oxide will be produced from 0.50 moles of oxygen?The balanced chemical equation for the reaction is:\[ 4\text{Al} + 3\text{O}_2 \rightarrow 2\text{Al}_2\text{O}_3 \]#### 4. Production of Calcium SulfideHow many grams of CaS are produced from 2.500 moles of CaO?The balanced chemical reaction is:\[ 4\text{HgS} + 4\text{CaO} \rightarrow 4\text{Hg} + 3\text{CaS} + \text{CaSO}_4 \]

Mole ratio depends upon the number of moles of Reactant and Products .Balanced Equation is C4H9OH + 6O2 → 4CO2 + 5H2O Now mole ratio is a) O2 to C4H9OH 6÷1 = 6 b) CO2 to H2O 4 ÷ 5 = 0.8 Ques 3 4Al + 3 O2 ----------> 2 Al2O3 3 moles of oxygen give 2 moles of Al2O3 1 mole will give 2/3 moles of Al2O3 0.5 MOLES WILL GIVE 2/3 ×0.5 = 0.333 moles of Al2O3 Ques 4 One mole of CaO produces 3 moles of CaS 2.5 moles of CaO produces 3/1 = 3 Total moles = 3* 2.5 = 7 moles of CaS Gram of CaS = moles × molar mass = 7 × 72 =504 g

The question is based on the following passage. Cathie remembers feeling exceptionally exhausted and irritable every January. After years of struggling with this "winter depression," Cathie went to talk to a physician about her health concerns. She was diagnosed as having Seasonal Affective Disorder, or SAD. Millions of Americans are also affected by this disease, which causes anxiety, fatigue, and food cravings. SAD is associated with lower intensity and abbreviated periods of sunshine. The dark, gloomy hours of winter along with the shortened days cause this disorder to be the most severe from November through March. People who suffer from Seasonal Affective Disorder claim to find relief with exercise and bright-light therapies. Based on the passage, where in the United States would a physician encounter the most cases of SAD? A. western lowa B. southwestern Arizona O C. northern Minnesota D. eastern Virginia E. southern Florida
