12 g of hydrogen reacts with 4 moles of oxygen then how many moles oof water will be formed?

Two moles of O2.

Four molecules of hydrogen are formed by eight atoms. With these eight atoms you can form four molecules of H2O, right? So you’ll need four oxygen atoms, that is, two molecules of it. Channge the word to moles and that’s it. Remenmber a mole is just a big bundle of particles (6.02x10^23) 602 thousand million million millions of them. The proportion holds the same for 1, 2, 10, 1000, 1000000 etc.

shield volcanos are angry and get mad over the smallest things so much that there heads erupt   pahoehoe and a'a lava. a composite volcano is the poller opposite of a shield volcano. its   peaceful thing and knows how to control its emotions.      

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
