That statement is true
Despite its cheap price, The usage of coal as an energy source will release <span>sulfur dioxide, nitrogen oxides, to the air around our environment.
This substance will give negative effects such as acidic rain that could be corrosive to our body and polluted air that is bad for our respiratory system.</span>
You can form 9.20 L of NH₃ gas at 93.0 °C and 37.3 kPa or 2.56 L at STP. The balanced chemical equation is N₂ + 3H₂ → 2NH₃ Since all substances are gases, we can use litres instead of moles in our calculations. You don't specify the pressure and temperature of the NH₃, so I will calculate its volume in two ways.
Answer:
Explanation:
The heat received by water is equal to the heat rejected by the piece of metal. That is to say:
The initial temperature of the piece of metal is:
On edgeunity it's option B, Half of a parent isotope undergoes radioactive decay to form a daughter isotope.
Pb because it has a average electric configuration
