N2O4 ↔ 2NO2
The following system react as below when increase in pressure occurs
The equilibrium will shift towards the left (more N2O4 is produced)
<em><u>Explanation</u></em>
When pressure increases the equilibrium shift toward the side of reaction with fewer moles of gas.
In the reaction of N2O4 ↔ 2 NO2 there is only 1 moles of N2O4 and 2 moles of NO2.
Therefore increase in pressure led to shift of equilibrium towards the left. ( more N2O4 is produced)
It’s molecular shape.
When the two hydrogen atoms bond with the oxygen, they attach to the top of the molecule rather like Mickey Mouse ears. This molecular structure gives the water molecule polarity, or a lopsided electrical charge that attracts other atoms. The end of the molecule with the two hydrogen atoms is positively charged.
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>
Answer:
5 pounds 2 ounces.
Explanation:
1 pound = 16 ounces
So just add the 2 ounces to the pounds.
A and C are incorrect because they are not complete transfer of valence electrons. Ionic bonds best to form a neutral molecule
