1) When three molecules of it are condensed in copper tube at 200°C, we get benzene: 1. Ethene 2. propene 3. butene 4. acetylene 2). Water gas reacts with hydrogen in the presence of certain catalysts to give: a. ethanol b. methanol c. ethene d. methanal​

If a plot weight (in g) vs. volume (in ml) for a metal gave the equation y= 13.41x and r^2=0.9981 what is the density of the metal?

If a 12-v battery is connected to a circuit that has a current of 3.0 a, what is the total resistance in the circuit? 36 ohms 4 ohms 0.25 ohms

What is the typical rotational frequency frot for a molecule like n2 at room temperature (25∘c)? assume that d for this molecule is 1å=10−10m. take the total mass of an n2 molecule to be mn2=4.65×10−26kg. you will need to account for rotations around two axes (not just one) to find the correct frequency. express frot numerically in hertz, to three significant figures.
