Answer:
Cobalt lose 3 electrons and donate 12 electrons.
Explanation:
In the periodic table,cobalt has nine electrons .It has lost 3 electrons,so it is only six left.Once it forms the complex,each ammonia donates a pair of electrons.
Answer:
The balanced chemical equation is given as:
![2NH_4NO_3\rightarrow 2N_2+O_2+4H_2O](https://tex.z-dn.net/?f=2NH_4NO_3%5Crightarrow%202N_2%2BO_2%2B4H_2O)
Explanation:
![NH_4NO_3\rightarrow N_2+O_2+H_2O](https://tex.z-dn.net/?f=NH_4NO_3%5Crightarrow%20N_2%2BO_2%2BH_2O)
During the balancing of the chemical reaction, balance all the atoms of every atoms except oxygen element.
There are 2 nitrogen atoms on both sides. Nitrogen atom is balanced.
There are 4 hydrogen atoms on left side and 2 hydrogen atom on right side.Write 2 in front of
to balance the hydrogen atoms.
![NH_4NO_3\rightarrow N_2+O_2+2H_2O](https://tex.z-dn.net/?f=NH_4NO_3%5Crightarrow%20N_2%2BO_2%2B2H_2O)
Now ,see the number of oxygen atoms on both sides. Here on both sides oxygen atoms oxygen atom are same.
So, write 2 in front of
, 2 in front of
and 4 in front of
.
![2NH_4NO_3\rightarrow 2N_2+O_2+4H_2O](https://tex.z-dn.net/?f=2NH_4NO_3%5Crightarrow%202N_2%2BO_2%2B4H_2O)
All the atoms of all each and every element is balanced in the chemical equation.
Explanation:
beryllium, calcium, strontium, barium, and radium; they are in the same group of table.
1) Radioactive decay is the spontaneous decomposition of the unstable nucleus of an atom.
2) The emission of a particle or a photon.
For example, alpha decay is radioactive decay in which an atomic nucleus emits an alpha particle (helium nucleus).
3) The result is usually more stable element with smaller atomic number.
For example, in alpha decay atom transforms into an atom with an atomic number that is reduced by two and mass number that is reduced by four.
For example nuclear fission is radioactive decay process in which the nucleus of an atom splits into smaller parts and huge amount of energy is released.
From the relationship between wavelength and frequency, the frequency of the wave is reduced by half to 60 Hz as the wavelength is increased twice to 10 m at constant speed.
<h3>What is the relationship between wavelength, velocity and frequency of a wave?</h3>
The velocity, frequency and wavelength of a wave are related by the formula given below:
where
- v is velocity
- f is frequency
- λ is wavelength of the wave
From the above relationship:
If the wavelength of a wave is increased to 10m but the speed stays the same at 600 m/s, the frequency can be calculated as follows:
f = v/λ
f = 600/10
f = 60 Hz
Therefore, the frequency of the wave is reduced by half as the wavelength is increased twice at constant speed.
