Answer:
72.04g Ti and 7.75g Na
Explanation:
1.505 mol Ti x (47.87g/1 mol) = 72.04g Ti
0.337 mol Na x (22.99g/1 mol) = 7.75g Na
Molecular wt if ethene = 28 g/mol
take 14 ÷ 28 = 0.5 mol
since there is a 1:1 ratio between ethene and ethanol one should produce 0.5 mol
MW ethanol = 46
0.5 × 46 = 23 g should be produced.
17.25/23 = 0.75 = 75% Percent yield
A chemical change alters the chemical makeup of a substance. So, wood burning would be a chemical change. The others just alter the physical makeup of the substance.
Answer:
Where does the exchange of the blood in the veins and oxygen in the lungs take place?
ALVEOLI are the very small air sacs where the exchange of oxygen and carbon dioxide takes place. CAPILLARIES are blood vessels in the walls of the alveoli. Blood passes through the capillaries, entering through your PULMONARY ARTERY and leaving via your PULMONARY VEIN
