A type of electromagnetic radiation would be electromagnetic waves
<span>The heating of the metal would result in an energy expenditure
</span>that would make mining copper counterproductive
<span>The expenditure of the process is comparative
to how much material (rock, dirt, whatever) you have to process. The more will
be the material to be route, the larger will be the equipment, or the longer you have
to run it, and the more power and other other materials you need. so that is why its expensive to extract copper from contaminated lan</span>

Answer:
The atomic mass of methane (CH4)is 12 amu for the carbon plus 4 x 1 amu for the four hydrogens, for a total of 16 amu. Therefore, the molar mass of methane is 16g.
Answer:
Mass = 28.59g
Explanation:
Q = 952J
Change in temperature = 37.0°C
Specific heat capacity = 0.90J/g°C
Mass = ?
Heat Energy (Q) = mc∇T
Q = heat energy
M = mass of substance
C = specific heat capacity of substance
∇T = change in temperature of substance
Q = mc∇T
952 = m × 0.90 × 37
952 = 33.3m
Solve for m
M = 952 / 33.3
M = 28.59g
The mass of aluminium required to use a heat energy of 952J is 28.59g
Here we have to get the alcohols which are formed in the reaction of an alkene with H₂SO₄ and H₂O.
The alcohols which are formed in the reaction between alkene and H₂SO₄ and H₂O are majorly secondary and tertiary alcohol. As primary alcohol only ethanol can be produced in this reaction.
The addition of H₂SO₄/H₂O generates alcohol from alkene. The general reaction is shown in the figure. In this reaction methanol (CH₃OH) cannot be prepared and in primary alcohol only ethanol (C₂H₅OH) can be prepared from ethene.
In case of propene and other higher alkene always secondary or tertiary alcohols are produced as the addition of sulphuric acid and water depends on the Markonikov's rule of addition to the less hindered position.
