Answer:
True
Explanation:
True
Ethanol is non-toxic, water soluble and biodegradable substance containing 35% oxygen, Ethanol blended fuel contains more oxygen gives more complete fuel combustion and reducing harmful tailpipe emissions. Ethanol displaces toxic gasoline components like benzene, a carcinogen.
Answer:
450. g of 0.173 % KCN solution contains 779 mg of KCN.
Explanation:
Mass of the solution = m
Mass of the KCN in solution = 779 mg
Mass by mass percentage of KCN solution = 0.173%
1 mg = 0.001 g
m = 450,289 mg × 0.001 g = 450.289 mg ≈ 450. g
450. g of 0.173 % KCN solution contains 779 mg of KCN.
Molarity is in units of moles/L. So you must determine the moles of CH3OH, then divide by the total volume.
To determine the moles of CH3OH, divide the weight in grams of CH3OH by the molecular weight
11.7g / 32g/mol = 0.366 mol CH3OH
0.366 mol CH3OH / .230 L = your molarity
Answer:
At 15.2°C. Kinetic energy of molecules highly depends on the temperature - the warmer it is, the faster the molecules will move, especially in fluids (gases and liquids). If we consider that the formula for average kinetic energy of molecules is:
Ek = 3/2*k*T where k is Boltzmanns constant and 3/2 is, well, 3/2, kinetic energy of molecules really only depends on the temperature.
Explanation:
Meat contamination because humans do not eat air or fertilizer so meat contamination is the only logical answer.
