You might want to check your code for typos. Those are common if you are used to typing using weird abbreviations.

Mole is a creature that digs tunnels in the ground. I believe the word you are looking for is mold.

You might want to look up the octet rule.

What are you trying to discuss here?

Step 1: what are the relevant formulas in both cases?

And you can scrape this quicklime from a natural source? Boiling water comes cheaply as well of course.

I think it will help if I reworded the question and it is basically a chicken or egg (lol) question. Is the smell of hydrogen sulphide associated to the smell of bad eggs or the other way around?

The balancing is done incorrectly. Dichromate is reduced to 2 Cr(III) ions, taking up a total of 6 electrons in the progress. Your reaction only deals with 2 of those. Although further ahead you do manage to come up with the correct equation.

The quran part of not eating pork and stuff was merely a survival guide. Now look what it became...-.-

One thing I see happening on this planet is that you have to provide the location where your weight was taken for your identification card.

It is usually preceded by the rear of the motorbike trying to overtake the front wheel, thereby rotating around it. This gives an acceleration to the ass of the driver.

Prime concern is how you would regenerate Na which requires more energy than what you ever could get from oxidizing H2.

So because we don't condemn homosexuality as being the spawn of hell we are of course all homosexuals ourselves. Nice ad hominem there. I ask you again to keep your opinions to yourself and try to act a little more professional.

No, doesn't happen in water. Kindly study some chemistry.

What is this 'god' thing you are talking about?

Finding same-gender attraction disgusting is a matter of opinion, not a scientific fact. Please leave such offending opinions at the doorstep.

Don't stare yourself blind on the molecular formula. CH3 doesn't have to indicate a methyl group, nor does NO2 automatically mean a nitrogroup.

That one is easy. He expects god to be thrown in there at some point.

Belief doesn't make things true.

It just happens. The DNA machinery isn't as perfect as you believe it to be. Copying DNA has a small chance of slipping errors into the copy which can influence development to a large extent, especially when this happens in the gamete stage. Depending on the environment (there we go) the organism with the mutation may or may not have a better chance to get laid (and thus pass on the mutation) than the organism without the mutation.

How does anything happen in evolution? One mutation at a time. And for the bearer of that mutation to get laid of course.

No harm done and I agree. Indeed, it is a process and many of its footprints and changes can be tracked by means of fossils. However, it is not a process towards a set end goal nor will it ever be 'complete'.

If you consider pressure to be [Pa] = [N]/m²; [N] = m*a and both weight and cross section are given, then you might be able to convert the piston into an additional pressure.

Nature didn't design anything. Don't pretend that evolution had any kind of conscious. Also it seems that the more social archetype actually survived. The Neanderthaler tribes were self-sustaining and there was little to no interaction between settlements, in contrast to the homo-erectus tribes that got a very primitive foreign aid going (one village helps another through a harsh winter and the first village is bound to receive help when they need it from the other village).

Organs? No. But they have managed to replace an entire cranium made by 3d-printing. http://singularityhub.com/2014/03/30/patients-cranium-replaced-with-custom-3d-printed-implant/
