What are the coordination numbers of li+ and s2− in the lithium sulfide crystal shown? enter the values in order of li+ and s2−,
Anna35 [415]
Answer:    
As there must be twice as many lithium ions as sulphide ions, the 'numbers'
must be different. 
 It's 4:8. i.e. 4 sulphides around each lithium; and 8 lithiums around each
sulphur. 
 It's an antifluorite structure.

DochEvi [55]

Answer:

The impurity which is present in the solution of copper sulphate (CuSO4) is determined by the an instrument known as spectrophotometer.

Explanation:

Spectrophotometer is a device or an instrument which is used to determine the concentration of a chemical by measuring the detection of light intensity that is coming from the solution. If the solution of copper sulphate is checked through spectrophotometer, we can can determined or measure the amount of copper sulphate and the impurity in the solution.

<h3>How Nuclear Fusion Reactors Work?</h3>

­W­hen hydrogen atoms fuse, the nuclei must come together. However, the protons in each nucleus will tend to repel each other because they have the same charge (positive). If you've ever tried to place two magnets together and felt them push apart from each other, you've experienced this principle firsthand.

To achieve fusion­, you need to create special conditions to overcome this tendency. Here are the conditions that make fusion possible:

High temperature gives the hydrogen atoms enough energy to overcome the electrical repulsion between the protons.

  • Fusion requires temperatures of about 100 million Kelvin (approximately six times hotter than the sun's core).
  • At these temperatures, hydrogen is a plasma, not a gas. Plasma is a high-energy state of matter in which all the electrons are stripped from atoms and move freely about.
  • The sun achieves these temperatures by its large mass and the force of gravity compressing this mass in the core. We must use energy from microwaves, lasers and ion particles to achieve these temperatures.

High pressure squeezes the hydrogen atoms together. They must be within 1x10-15 meters of each other to fuse.

  • The sun uses its mass and the force of gravity to squeeze hydrogen atoms together in its core.
  • We must squeeze hydrogen atoms together by using intense magnetic fields, powerful lasers or ion beams.

Green plants absorb sunlight to power photosynthesis, the chemical synthesis of food from water and carbon dioxide. The compound
Alecsey [184]

Answer:

4.5 × 10^14 Hz

Explanation:

According to this question, chlorophyll pigment strongly absorbs light with a wavelength of 662nm. To calculate the frequency of this light, the following formula is used:

λ = v/f

Where;

λ = wavelength (m)

v = speed of light (3×10^8m/s)

f = frequency of light (Hz)

Since the λ = 662nm = 662 × 10^-9m,

f = v/λ

f = 3 × 10^8/662 × 10^-9

f = 0.004531 × 10^(8+9)

f = 0.0045 × 10^17

f = 4.5 × 10^14 Hz
