Answer:
n = 0.34 mol
Explanation:
Given data:
Given temperature = 789 K
Pressure = 765 torr ( 765/760 = 1.0 atm
Volume of container = 22.0 L
Number of moles of gas = ?
Solution:
Formula:
PV = nRT
n = PV/RT
n = 1.0 atm × 22.0 L / 0.0821 atm.L/mol.K ×789 K
n = 22.0 L.atm /64.8 atm.L/mol
n = 0.34 mol
Explanation:
The definition of Loam is soil composed mostly of sand, silt, and a smaller amount of clay. By weight, its mineral composition is about 40–40–20% concentration of sand–silt–clay, respectively..
Answer:
1) 40
2) 2.25 moles
3) 17
4) 120
5) Fe₂O₃
Explanation:
Please see attached picture for full solution.
The answer would be A will increase and T <span>will decrease.
The product of this reaction emits red light because it absorbs green and blue light. As the reaction occurs, the concentration of the product increase. This will makes absorbance of green and blue light increases and the solution will become redder.</span>
