Answer:
Energy, 
Explanation:
It is required to find the energy of an electromagnetic wave with a frequency of 
. The energy of a wave in terms of its frequency is given by :
= frequency of em wave
So, the energy of an electromagnetic wave is 
yes
Explanation:
the molar mass of a compound is g/mol
Answer:
it shows the breakdown of the atom
Explanation:
it will show it molecularly
The reaction between the magnesium, Mg, and the hydrochloric acid, HCl is given in the equation below,
Mg + 2HCl --> H2 + MgCl2
The number of moles of HCl that is needed for the reaction is calculated below.
n = (0.4681 g Mg)(1 mol Mg/24.305 g Mg)(2 mol HCl/1 mol Mg)
n = 0.0385 mols HCl
From the given concentration, we calculate for the required volume.
V = 0.0385 mols HCl/(0.650 mols/L)
V = 0.05926 L or 59.26 mL
<em>Answer: 59.26 mL of HCl</em>
Wouldn't be a then not c if both were solutions.
