When 50.08 g of 1.00 m naoh at 23 °c is added to 50.22 g of 1.00 m hcl at 23 °c, the resulting temperature of the mixture is 29.7 °c. (assume that the calorimeter constant is equal to zero. assume that the solutions have the same specific heat capacity (4.184j / gk) and density (1.00g / ml) as water. what is the qsolution, enthalpy change, and is it endothermic or exothermic? .

Ethanol (c2h5oh) is produced from the fermentation of sucrose in the presence of enzymes. c12h22o11(aq) + h2o(g) 4 c2h5oh(l) + 4 co2(g) determine the theoretical yield and the percent yields of ethanol if 680. g sucrose undergoes fermentation and 326.5 g ethanol is obtained. theoretical _ g _ percent %

Read the claim. breakfast is an important meal. it jump starts the body’s process of using calories to break down food. appetite can decrease with age, but going too long without eating causes metabolism to slow down. current research shows that incorporating legumes such as lentils and chickpeas into meals boosts metabolism for twenty-four hours. who might benefit from this claim? people who have a fast metabolism stores that sell exercise equipment people who take vitamin supplements grocery stores that sell legumes
