For the reaction 2H2 plus O2 equals 2H2O how much water is produced when 2.5 moles of hydrogen react completely How do you do the problem?
2H2 + O2 ---------------> 2H2O for every 2 moles of hydrogen that reacts, 2 moles of water are produced, thus a 1:1 ratio of water produced to hydrogen reacted. So:- 2.5 moles of hydrogen reacted will produce 2.5 moles of water
Is hydrogen a nonrenewable resource?
This is not a problem, hydrogen is very abundant.
Why is free nitrogen a problem for organisms?
When nitrogen is inhaled at high pressure (over 4 atmospheres) in organism is the cause of nitrogen narcosis.
How many grams of water are produced when 300 grams of hydrogen react with an unlimited amount of oxygen?
The atomic mass of hydrogen is 1.008 and the molecular mass of water, with formula H2O, is 18.015. Therefore, the mass of hydrogen to that of water has the ratio of 2(1.008)/18.015 = about 0.1119, and the answer to the problem is 300/0.1119 = 2.68 X 103 grams, to the justified number of significant digits.
Why should you not enclose car batteries without air flow?
Car batteries sometimes generate hydrogen gas during charging. If the battery is enclosed without air flow this hydrogen could build up to explosive levels and a small spark could trigger an explosion. When air flow is allowed the hydrogen cannot build up, making an explosion impossible. Note: this is ONLY a problem with car batteries, not dry cells or lithium batteries.
What is the big problem with hydrogen fuel cells?
The main problem is that the hydrogen gas is difficult to store. Since it would have to highly pressurised, it would be inconvenient and dangerous to store in cars/automobiles.
Why can smelly gas produced in a factory move long distances from where it was produced?
because it can got a problem
Why is what to produce a problem in every economy?
What to produce?There are two aspects of this problem--- firstly, which goods should be produced, and secondly, what should be the quantities of the goods that are to be produced. The first problem relates to the goods which are to be produced. In other words, what goods should be produced? An economy wants many things but all these cannot be produced with the available resources.Therefore, an economy has to choose what goods should be produced and what goods should not be. In other words, whether consumer goods should be produced or producer goods or whether general goods should be produced or capital goods or whether civil goods should be produced or defense goods. The second problem is what should be the quantities of the goods that are to be produced.Production of goods depends upon the use of resources. Hence, this problem is the problem of allocation of resources. If we allocate more resources for the production of one commodity, the re­sources for the production of other commodities would be less.

One problem with fuel-cell cars is that gas is not readily available in pure form?
Answer this question… One problem with fuel-cell cars is that ________ gas is not readily available in pure form.
What does iodine smell like?
Sort of. Lithium has been describes as smelling like ammonia. This is not the lithium itself, but due to a chemical reaction. The lithium reacts with nitrogen in the air to form lithium nitride. That in turn reacts with moisture to form lithium oxide and ammonia.
Why are lithium-related memory problems often reported by lithium-users and their relatives but seldom found in a scientific study?
Memory problems are a known problem in functional psychosis ( schizophrenic, and depressive patients ) so it would be very hard to dissect out the contribution to memory problems that were solely due to taking lithium even if it existed. Furthermore, an ill and untreated patient would not care too much about memory problems while suffering depression or psychosis. It doesn't mean that the problem doesn't exist, just that it is being masked by a more serious problem.
