Answer:
40.1 g
Explanation:
The <em>balanced equation</em> is:
First we <u>convert 86.5 g of calcium chlorate into moles</u>, using its<em> molar mass</em>:
- 86.5 g Ca(ClO₃)₂ ÷ 206.98 g/mol = 0.418 mol Ca(ClO₃)₂
Then we <u>convert Ca(ClO₃)₂ moles into O₂ moles</u>, using <em>the stoichiometric coefficients of the balanced reaction</em>:
- 0.418 mol Ca(ClO₃)₂ *
= 1.254 mol O₂
Finally we <u>convert O₂ moles into grams</u>:
- 1.25 mol O₂ * 32 g/mol = 40.1 g O₂
First of all, the formula for finding Kelvin is Celsius + 273
Therefore, if we subtract 273, we get the temperature in degrees
120 - 273 = - 153
Therefore, the answer is (1), or -153 degrees Celsius
Hope this helped!! :D
The ammonia gas is absorbed in the concentrated brine to produce aqueous sodium chloride and aqueous ammonia. This ammoniation process is exothermic, so energy is released as heat. The ammonia tower eventually needs to be cooled.
Answer:
Mass = 255 g
Explanation:
Given data:
Number of moles of nitrogen = 7.5 mol
Mass of ammonia formed = ?
Solution:
Chemical equation:
3H₂ + N₂ → 2NH₃
Now we will compare the moles of nitrogen and ammonia.
N₂ : NH₃
1 : 2
7.5 : 2/1×7.5 = 15
Mass of ammonia:
Mass = number of moles × molar mass
Mass = 15 mol × 17 g/mol
Mass = 255 g
