The answer is carbon dioxide
<span>Magnetic domain
Its speed can be slowed because the magnetic field can be turned on and off, can have its direction reversed and can have its strength changed. However, The speed of a magnetic field that is produced by a current is impossible to be slowed. </span>
Vertical angles should be your answer

Answer:
X = 5
Explanation:
Total mass here is 1.5g. Now after heating we have a mass of 0.957g Cu. This means heating had caused a loss of 1.5 - 0.957 = 0.543g of water.
Now, we will try to convert this into moles. This can be done by dividing the respective masses by the molar masses. While the mass of water is 18g/mol, the molar mass of CuSO4 is 160g/mol.
The division of the respective masses by the molar masses is thus:
CuSO4 = 0.957/160 = 0.006 moles
H2O = 0.543/18 = 0.03 moles
The ratios of the moles is thus: 0.03/0.006 = 5
Hence, the number of molecules of water of crystallization is 5
This means x = 5
