Solid! The molecules in solid matter are arranged closely together and packed quite tightly to maintain a regular shape. Hope this helps!
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>
The will not affect the wind. When it is windy the wind turns a turbine. Once the wind has gone through the turbine it is just normal wind, none of the wind is lost when this happened
As thermal energy increases and there is more particle movement.
- Thermal energy is the energy possessed by the system or object due to the movement of its particles.
- For example kinetic energy of the particles
- Higher the motion of the particles more will be the thermal energy of the system or object and vice-versa
- It is also termed as heat energy of a system or object
- The higher the thermal energy, the higher will be the temperature and vice versa.
So, from this, we can conclude that as thermal energy increases and there is more particle movement.

The molecular weight of water is <span>18.01528 g/mol.
So in 2.92 grams there are 2.92/</span>18.01528 = 0.1621 mol of particles.
1 mol contains 6,02214 × 10^<span>23 particles by definition.
So the nr of H2O molecules is </span>0.1621 * 6,02214 × 10^23 = 0,9761 × 10^23.
Every molecule has 2 H atoms, so you have to double that.
2* 0,9761 × 10^23 = 1.952 × 10^23.
