Explanation:
this is a process used in industrial preparation of ammonia were nitrogen react with hydrogen in presence of a catalyst iron (2) oxide in a temperature of about 450c
Hi there!
We can use the following conversions to solve:
Total mass --> amount of mols --> amount of atoms (Avogadro's number)
Begin by calculating the amount of boron trifluoride in 3.61 grams:
3.61 g * (1 mol BF₃ / 67.8 g) ≈ 0.0532 mol BF₃
Use avogadro's number to convert:
0.0532 mol * 6.02× 10²³atoms / 1 mol = 3.203 × 10²² atoms
Answer:
YIkES One thing u can do i ask your teacher about it or say that u need help with it the cant make fun of u because u need help with your work.
1 mole of NO2= 7 + (8×2)= 7 + 16 = 23g
81g of NO2 = 81÷23 = 3.5217
Ans = 3.5 moles ...//
<span> reason is that there is no land to slow down the wind. Also, wind is caused by differences in air pressure</span>
