When a gas bubbles through water, small droplets of water are usually picked up along for the ride and are mixed in with the gas above the water inside the eudiometer tube. The water vapor takes up room, but isn't the important gas that you need to measure. The table of water vapor is needed to subtract the unwanted water vapor from the collection of gases.
Answer:
0.7 g/cm³

< The formula for density is 
where m = mass, v = volume, and p = density. An easy way to remember the formula is density equals love. I found this easy to remember because p = ♡ and when you think about it, if you split the heart in half through the middle like a fraction, it will make 
(if you don't understand what I'm saying, try writing it out and you will be able to see what I'm talking about!)
We already know that the block is 253 g so the mass is 253 g.
To find the volume, always multiply the 3 values width, length, and height whenever you are trying to find the volume of a block.
15.24 cm x 6.64 cm x 3.56 cm = 360.25 cm³
Now plug it into the formula.

I believe it is B. A series circuit has one path for electrons, but a parallel circuit has more then one path.

To calculate the mass of Fe formed in a) we get first the limiting reactant between Fe2O3 and CO. Given the masses, the ratio of Fe2O3 is 1.33 while that of CO is 1.67. Hence the limiting reagent is Fe2O3. The mass of Fe formed is 148.98 grams. In b, the needed CO is only 112.04 grams. Hence, the excess is 27. 96 grams.
B and temp is related to kinetic energy by how they both effect the speed of the particles. If the temp is hot the particles speed up and if cold the particles slow down
