Answer:
Copper electrical wires are safer to use than wires made of most other conductive metals because they are resistant to heat. As you can see, copper is the preferred metal for electrical wires for several reasons. It has high electrical conductive; it's inexpensive; it's ductile; and it's thermal resistant.
Answer:
∆H or Enthalpy of the reaction
Explanation:
If ∆H is +ve
- Reaction is exothermic
- Example:-Combustion, mixing sodium/potassium in water
If ∆H is -ve
- Reaction is endothermic
- Ex:-Melting of ice
Answer:
pollution causes smog
Smoke fog, or smog for short, is a type of intense air pollution.
it makes GHG wich is greenhouse gas and it makes the smog to stay inside the earth wich heats the Earth and it causes flood, storm, tornadoes, ect.
The moles of ammonium nitrate needed to dissolve 0.35 moles
The moles of water that will react is 0.35 moles as due to ratio
so mass of water will be 0.35 x 18=6.3g
MASS OF WATER WILL BE 6.3 g
Answer: 1 dissociation. 2. Hydration. 3. Dissolving.
