Answer:
0.0423 L
Explanation:
Molarity can be represented by the following ratio:
Molarity = moles / volume (L)
You can plug the given values into the equation and simplify to find the volume.
Molarity = moles / volume
0.730 M = 0.0309 moles / volume
(0.730 M) x volume = 0.0309 moles
volume = 0.0423 L
Density is equal to the mass of the substance per volume it occupies. In ths case, the density of gold from literature is 19,300 kg/m3 or 19.3 g/cm3. Given the volume of <span>4.20cm^3 , the mass is obtained by multiplying density and volume to get 81.06 grams of gold</span>
Answer:Free radical mono-halogenation of an alkane is typically conducted using bromine versus chlorine because the bromine radical is less reactive and therefore more selective.
Explanation: Halogenation occurs when a halogen replaces one or more hydrogen atoms in an organic compound ie chlorine or bromine with the reactivity of the halogens decreasing in the order of F2 > Cl2 > Br2 > I2
Since fluorine reacts explosively making it is difficult to control, and iodine is unreactive. Free radical mono-halogenation of an alkane is typically conducted using bromine versus chlorine with Chlorination ie chlorine radical being more reactive and not selective and the Bromination of alkanes ie bromine radical occurring similarly but slower and less reactive but more selective which is due to the fact that a bromine atom is less reactive in the hydrogen abstraction than a chlorine atom evidence in the higher bond energy of H-Cl than H-Br.
I choose the letter c witch is density I believe that it’s useful for determining identifying relationships between substances
Answer:
Compare Silicon and Sulfur on the basis of their properties, attributes and periodic table facts. Compare elements on more than 90 properties. All the elements of similar categories show a lot of similarities and differences in their chemical, atomic, physical properties and uses. These similarities and dissimilarities should be known while we study periodic table elements. You can study the detailed comparison between Silicon vs Sulfur with most reliable information about their properties, attributes, facts, uses etc. You can compare Si vs S on more than 90 properties like electronegativity , oxidation state, atomic shells, orbital structure, Electronaffinity, physical states, electrical conductivity and many more.
