True is your answer so true
Answer: The answer is frequency.
Explanation: If the wavelength is long, the frequency will be low. If the wavelength is short, the frequency will be high.
Answer:
The metal element → Magnesium (Mg)
The first one is right and so is eight you have to add them together to see if they go together if they dont add what is missing
Answer:
S = 21.92 %
F = 78.08 %
Explanation:
To find the percent composition of each element in SF6, we must find the molar mass of SF6 first.
Molar mass of SF6 = 32 + 19(6)
= 32 + 114
= 146g/mol
mass of Sulphur (S) in SF6 = 32g
mass of Fluorine (F) in SF6 = 114g
Percent composition = mass of element/molar mass of compound × 100
- % composition of S = 32/146 × 100 = 21.92%.
- % composition of F = 114/146 × 100 = 78.08%.
