Answer:
1.345*10⁻⁴ mol/L
15.023 mg/L
Explanation:
The chemical <u>formula of ferrocene</u> is Fe(C₅H₅)₂, thus its molecular weight is:
55.845 g/mol + 10*12g/mol + 10 *1g/mol = 185.845 g/mol
- The moles of Fe contained in 25 mg (or 0.025 g) of ferrocene are:
- The final volume is 500 mL, or 0.5 L. So the iron concentration in mol/L is:
- We can convert that value into mg/L:
The answer is:
C) Sound is a mechanical wave and needs a medium to travel through while light is an electromagnetic wave.
If large amounts of waste were dumped into the Missouri River, the dissolved oxygen levels would go down significantly and kill many of the organisms in the river.
Cu(OH)2 is the precipitate that forms
Answer: In order for reflection to occur, the wave must “bounce off” an object
Explanation: For example if your looking in the mirror the waves are bouncing off the mirror to reflect your image
