ph ch3 h2nnh koh The Wolff-Kishner reaction involves the reaction of an aldehyde/ketone with hydrazine in the presence of KOH. T

he process is useful for converting an aldehyde or ketone into an alkane. The reaction involves formation of a hydrazone, followed by base-catalyzed double-bond migration, loss of N2 gas to give a carbanion, and protonation to give the alkane. Draw curved arrows to show the movement of electrons in this step of the mechanism.

Since volume and temperature are constant, this means that pressure and_____are____proportional. the sample with the largest____
IceJOKER [234]

Since volume and temperature are constant, this means that pressure and <u>number of moles</u> are <u>directly </u>proportional. the sample with the largest <u>number of moles</u> will have the <u>high </u>pressure.

Since, the ideal gas equation is also called ideal gas law. So,  according to ideal gas equations,

PV = nRT

  • P is pressure of the sample
  • T is temperature
  • V is volume
  • n is the number of  moles
  • R is universal gas constant

At constant volume and temperature the equation become ,

P ∝ nR

since, R is also constant. So, conclusion of the final equation is

P  ∝ n

The number of moles and pressure of the sample is directly proportion. So, on increasing number of moles in the sample , pressure of the sample also increases.

1. How many milliliters of 10.0 M HNO 3 are needed to prepare 0.350 L of 0.400 M solution?
tatyana61 [14]
<h3>Answer:</h3>

14 milliliters

<h3>Explanation:</h3>

We are given;

  • 10.0 M HNO₃

Prepared solution;

  • Volume of solution as 0.350 L
  • Molarity as 0.40 M

We are required to determine the initial volume of HNO₃

  • We are going to use the dilution formula;
  • The dilution formula is;

M₁V₁ = M₂V₂

Rearranging the formula;

V₁ = M₂V₂ ÷ M₁

    =(0.40 M × 0.350 L) ÷ 10.0 M

   = 0.014 L

But, 1 L = 1000 mL

Therefore,

Volume = 14 mL

Thus, the volume of 10.0 M HNO₃ is 14 mL

Fluorine (F) has seven electrons in its outermost shell. Fluorine _____.
kow [346]
Fluorine is a nonmetal and as such it would need to take in or obtain an electron from a metal to have a stable octet, or full number of 8 electrons in its valence shell. Thus due to the indifference of electrons and protons it becomes an anion, a negatively charged ion.
