A. NaCl(s) and O2(g)
B. 2NaClO3(s) —> 2NaCl(s) + 3O2(g)
C. moles NaClO3 = 100 g / 106.44 g/mol = 0.939 mol NaClO3
D. 0.939 mol NaCl (because the NaClO3 and NaCl are in a 1 to 1 ratio)
E. grams NaCl = 0.939 mol • 58.44 g/mol = 54.9 g NaCl
F. moles of O2 = 0.939 mol NaClO3 • (3 mol O2 / 2 mol NaClO3) = 1.41 mol O2
G. grams of O2 = 1.41 mol • 32 g/mol = 45.1 g O2
H. Percent yield = 10/45.1 • 100% = 22.2% yield
Answer:
Alkanes
Explanation:
The description of the first molecule corresponds to a cycloalkane. In the cycloalkanes for each carbon atom there are 2 hydrogen atoms (CnH2n = C5H10).
The second molecule corresponds to an open chain alkane, where for every carbon atom there is double plus 2 hydrogen atoms (CnH (2n + 2) = C5H12)
Answer: The correct answer is C) carbon dioxide; calcium.
Explanation:
Carbonated soft drinks contain big concentrations of carbon dioxide, which is the bubbles that we see and feel. When these drinks are included regurly in the diet, the carbon dioxide levels are increased; and according to several studies high carbon dioxide values are related with bone loss.
Additionally, calcium is known for being an important nutrient for both formation and maintenance of bones, so inadequate intake of calcium in the diet results in a bone loss.
The answer is storm surge
