N2 + 3H2 ----> 2NH3
<span>you can see 3 moles H2 reacts to form 2 moles NH3 </span>
<span>Therefore moles NH3 = 2 / 3 x moles H2 </span>
<span>= 2/3 x 12.0 mol </span>
<span>= 8.00 mol NH3 hope this help</span>
Answer:
The answer to the question is
The star’s approximate radial velocity is 68.52 km/s
Explanation:
To solve the
The formula is
where
= velocity of the star
λ = Star's spectrum wavelength = 656.45 nm
= Rest wavelength = 656.30 nm
c = Speed of light = 299 792 458 m / s
Therefore we have
or
= 68518.7699 m/s or 68.52 km/s
Solubility of KMnO4 in water is 6.4 g/100mL Which means maximum of 6.4 g of KMnO4 can dissolve in 100 mL of water. ... And in given situation, 0.35 moles are added to 500 mL of water which is off the limit and thus it cannot be dissolved completely.
