How many moles of NH3 can be formed from 3 moles of N2 and 6 moles of H2?
The balanced chemical equation for the formation of NH3 from N2 and H2 is: N2 + 3H2 -> 2NH3 From the equation, we can see that 1 mole of N2 reacts with 3 moles of H2 to produce 2 moles of NH3. Therefore, if we have 3 moles of N2 and 6 moles of H2, we have enough H2 to react with all the N2. This means that 3 moles of N2 will produce 2 moles of NH3.
-
Are such moles normal?
Yes, moles are common and normal. Most adults have between 10-40 moles on their body, which are usually harmless. However, it is important to monitor moles for any changes in size, shape, or color, as this could be a sign of skin cancer. If you notice any concerning changes in your moles, it is recommended to consult a dermatologist for further evaluation.

How many moles of hydrogen are contained in 348 moles of H2O?
There are 696 moles of hydrogen contained in 348 moles of H2O. This is because each mole of H2O contains 2 moles of hydrogen atoms. Therefore, to find the number of moles of hydrogen in 348 moles of H2O, we simply multiply 348 by 2.
-
How many moles of methanol can be produced from 15 moles of hydrogen?
The balanced chemical equation for the production of methanol from hydrogen is: 2H2 + CO -> CH3OH From the equation, we can see that 2 moles of hydrogen are required to produce 1 mole of methanol. Therefore, if 15 moles of hydrogen are used, then 15/2 = 7.5 moles of methanol can be produced.
