Wave length measures the width of the wave
Will cause sea levels to fall
The percentage composition of CF4 is %C = 13.64% and %F = 86.36%
The solution are as follows:
Molar mass of CF4 = 88
<span>molar mass of C = 12 </span>
<span>molar mass of F = 4x19 = 76 </span>
<span>% C = 12/88 x 100 = 13.64% </span>
<span>% F = 76/88 x 100 = 86.36%</span>
Answer:
When mechanical waves strike a barrier, at least part of the energy of the waves will be reflected back into the media from which they came.
Explanation:
Explanation:
If the compounds are dissociated, the ions are:
NH₄BY NH₄⁺ BY⁻
K₂HPO₄ K⁺ HPO₄²⁻
CuNO₃ Cu⁺ NO₃⁻
The given compounds assuming that they dissociate in solutions will produce the ions listed above.
The cations which are the positively charged ions in the above compounds are made up of metals and radicals.
The anions which are negatively charged ions are purely chemical radicals.
