Answer:
C. 662.60
Explanation:
the mass of Mn is about 54 grams/mol, (multiply that by 2 since there are 2 Mn's).
the mass of Se is about 79 grams/mol, so multiply that by 7
if you add them, you get 662.60 (approxamitly)
Explanation:
The purpose of insulation covering the metal part of an electrical wire is to prevent accidental contact with other conductors of electricity, which might result in an unintentional electric current through those other conductors
or
Most electrical wire is covered in a rubber or plastic coating called insulation. The purpose of insulation covering the metal part of an electrical wire is to prevent accidental contact with other conductors of electricity, which might result in an unintentional electric current through those other conductors
so does this helps?
Answer:
Reversible chemical reaction favoring products.
Explanation:
Hello,
In this case, if we assume the following chemical reaction to be carried out:
We understand that it is under equilibrium conditions. In addition, based on the law of mass action, the present equilibrium constant is defined as:
Now, if Keq is greater than 1, it means that the concentration of the product B is greater than that of the reactant A, therefore, even though it is a reversible chemical reaction, it is favoring the formation of B it means the product(s).
Best regards.
Answer:
1.21 times
Explanation:
The energy of a wave is proportional to the square of the amplitude of the wave.
Mathematically:
where
E is the energy of the wave
A is its amplitude
In this problem, the amplitude of the wave increases by a factor of 1.1; it means that the new amplitude can be written as
Therefore, this means that the energy of the wave increases by a factor:
Therefore, the energy of the wave increases by a factor 1.21.
