Answer:
The concentration of CH₃OH in equilibrium is [CH₃OH] = <em>2,8x10⁻¹ M</em>
Explanation:
For the equilibrium:
CO (g) + 2H₂(g) ⇄ CH₃OH(g) keq= 14,5
Thus:
14,5 =
In equilibrium, as [CO] is 0,15M and [H₂] is 0,36M:
14,5 =
Solving, the concentration of CH₃OH in equilibrium is:
<em>[CH₃OH] = 0,28M ≡ 2,8x10⁻¹ M</em>
I hope it helps!
Explanation:
molarity=no. of moles of solute/solution in litres
6.17M=no. of moles of solute/9.4 L
6.17×9.4=no. of moles of solute
57.9 =no. of moles of potassium fluoride KF
no. of moles=given mass /molar mass
57.9=given mass/58
3358.2 g
One atmosphere is equal to 101.3 kilopascals, the measurement of force that the atmosphere exerts at sea level. To convert 112 atmospheres to kilopascals, simply multiply the two together.
112 atm x (101.3 kPa/1 atm) = 11,345.6 kPa
/\
conversion factor
112 atmospheres is the same amount of pressure as 11,345.6 kilopascals.
Answer:
<em>There would be an increase in temperature and corresponding increase in the volume of the balloon</em>
Explanation:
Charles law is been here
Charles law states that the volume of a given mass of gas is directly proportional to the temperature in Kelvin, provided that the pressure on the gas is kept constant. Mathematically Charles law can be represented thus;
V∝ T
Where V is the volume of the gas and;
T is the temperature.
Relating Charles Law to the question
- The child moved outside from the room, constant atmospheric pressure is maintained.
- The temperature of the room is lower than the temperature outside.
From Charles law postulation, there would be an increase in volume because of the increased temperature, since our pressure is same.
