Answer:
the conjugate base of the compound is
C6h6O2/6-
Explanation:
subscript
Mass cannot be created nor destroyed as well.
So, energy just goes into other things.
Example: you are born. You have carbon dioxide in your body, (or star dust). When you die, your body releases that gas.
Make sense?
I hope this helps! (:
Answer: Left Arrow Far right arrow and center left arrow
Explanation:
These three arrows are correct due to heat transfers to cooler temp environments which allows the expansion of speed for molecules in their environment.
To determine the fraction of carbon in morphine, we need to know the chemical formula of morphine. From my readings, the chemical formula would be <span>C17H19NO<span>3. We assume we have 1 g of this substance. Using the molar mass, we can calculate for the moles of morphine. Then, from the formula we relate the amount of carbon in every mole of morphine. Lastly, we multiply the molar mass of carbon to obtain the mass of carbon. We calculate as follows:
1 g </span></span> <span>C17H19NO<span>3 ( 1 mol / 285.34 g ) ( 17 mol C / 1 mol </span></span> <span>C17H19NO3</span>) ( 12.01 g C / 1 mol C) = 0.7155 g C
Fraction of carbon = 0.7155 g C / 1 g <span>C17H19NO<span>3 = 0.7155</span></span>
