This type of water pollution is known as thermal pollution. Thermal pollution is the release of heat into the environment. In the case of power plants they release heated water into waterways. Water is used in power plants to cool down machinery. As machines operate they release heat so the water is used as a coolant. Releasing heated water into an aquatic ecosystem reduces the oxygen carrying capacity of the water, so less oxygen is available for organisms to use for respiration.
The correct option is C.
Isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. Isotopes have different relative atomic mass but share the same chemical properties.
Answer: Yes , in , two electrons from magnesium are transferred to chlorine atoms.
Explanation:
Ionic compound is formed by the transfer of electrons. For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.
For example : For formation of
Electronic configuration of magnesium:
Magnesium atom will loose two electrons to gain noble gas configuration and form magnesium cation with +2 charge.
Electronic configuration of chlorine:
Chlorine atom will gain one electron to gain noble gas configuration and form chloride ion with -1 charge.
In Magnesium chloride two electrons from magnesium metal gets transferred to two chlorine atoms and thus is formed.
Mass of Nd₂(SO₄)₃ : 2.653 g
<h3>Further explanation</h3>
Reaction
Nd₂Fe₁₄B + 17H₂SO₄ → Nd₂(SO₄)₃ + 14FeSO₄ + B + 17H₂
5 g Nd₂Fe₁₄B
MW = 2. 144,242 + 14. 55.845 + 10.811
MW = 288.484 + 781.83+10.811=1081.125 g/mol
mol :
mol Nd₂Fe₁₄B = mol Nd₂(SO₄)₃=0.0046
so mass of Nd₂(SO₄)₃ :
MW Nd₂(SO₄)₃ = 2.144.242+3.32,065+12.15,999
MW = 288.484+96.195+191.988=576.667 g/mol
