Answer: The nitronium ion is a strong electrophile
Explanation:
The detailed mechanism of the reaction is shown in the images attached. The flow of electrons has been shown with arrows. HNO3 is first protonated by H2SO4 this protonated specie H2NO3+ now forms H2O and NO2+.
Answer:
science is nothing without funding
Explanation:
Well Science in the US is highly a political affair. Scientists need funding for research, so they usually have to obtain grants from people who have the means to spare it. In many cases that means people who are involved with the government, or have close ties to it.
So scientists find themselves having to play off partisan politics in order to secure the funding they need for their research. Many times they also find that their research will inevitably get skewn to meet the original funders own ends.
Mostly what I have said is commonly known. However I am in school, and deal with scientists and doctoral researchers who have expressed and validated similar experiences.
Answer:
D. 76%
Explanation:
Percent yield=actual/theoretical * 100
38/50 * 100 = 76%
<span>0.15 = 255.0 / X ---> </span><span>X = 255.0 / 0.15 </span>
<span>X = 1700g </span>
<span>(H2O + NaCl) - (NaCl) = H2O </span>
<span>1700g - 255g = 1445g
</span>
The mass of water would be 1445g.
Varuable, In algebra, a symbol (usually a letter) standing in for an unknown numerical value in an equation :)
