Answer:
By decreasing the volume, the equilibrium will shift to the side with the smallest amount of particles
Explanation:
Step 1: Data given
The principle of Le Chatelier says:
When the volume is decreased, the equilibrium will shift to the side of the smallest number of particles.
2NOBr(g) ⇌ 2NO(g)+Br2(g)
In the following example, we have 2 moles of NOBr (on the left side) and 3 moles of gas on the right side. This means the left side, the reactant side, has the smallest number of particles.
The equilibrium will here shift to the left side, the side of NOBr.
In the following example
2NO2(g) ⇌ N2O4(g)
We have 2moles of NO2 on the left side and 1 mol of N2O4 on the right side.
By decreasing the volume, the equilibrium will shift to the side of the smallest number of moles. Here this is the right side, the side of N2O4.
Answer:
1: A b/c the table is showing that each different surface resulted in different time for acceleration.
2: D b/c the if the same force is applied to two different masses, the smaller masses would be impacted more and move faster. The larger an object is, then the greater the force you will need for it to move the same distance as the smaller masses.
Number 1 is D because 124-110 is 14n in team 1s favor so it moves towards team 1
Answer:
The answer is: 11759 Hz
Explanation:
Given: Chemical shift: δ = 211.5 ppm, Spectrometer frequency = 556 MHz = 556 × 10⁶ Hz
In NMR spectroscopy, the chemical shift (δ), expressed in ppm, of a given nucleus is given by the equation:
<u>Therefore, the signal is at 11759 Hz from the TMS.</u>
Answer:
4.88 kg
Explanation:
Amount of energy generated in 1 hour of exercise = 5500 kJ
Thus,
Amount of energy generated in 2 hours of exercise = 5500*2 kJ
So,
Amount of energy generated in 2 hours of exercise = 11000 kJ
Heat of vaporization of water = 40.6 kJ/mol
40.6 kJ of energy is required to vaporize 1 mole of water
Also,
11000 kJ of energy is required to vaporize (1/40.6) * 11000 mole of water
Moles of water = 270.936 moles
Molar mass of water = 18 g/mol
Mass = Moles * Molar mass = 270.936 * 18 g = 4876.8473 g
Also,
1 g = 0.001 kg
So, mass of water = 4.88 kg
