3 0

Answer:

a. 1-fluoro-3,3,4-trimethyl-pentane.

b. 1-iodo-3-ethyl-2-methyl-hexane.

c. 1,3-dichloro-5-dimethyl-hexane.

d. 1-bromo-3-methyl-cyclopentane.

Explanation:

Hello!

In this case, according to the IUPAC rules for the listed alkyl halides, we first need to name the halogens (considering periodic order) then alkyl radicals and finally the parent chain; thus, the names are given below:

a. 1-fluoro-3,3,4-trimethyl-pentane.

b. 1-iodo-3-ethyl-2-methyl-hexane.

c. 1,3-dichloro-5-dimethyl-hexane.

d. 1-bromo-3-methyl-cyclopentane.

e. 5-chloro-1-bromo-1,1,5-trimethyl-pentane (radicals are not clear).

Best regards!

Paraphin [41]

<u>Answer:</u> The symbol of the ion formed is Ca^{2+}

<u>Explanation:</u>

An ion is formed when a neutral atom looses or gains electrons.

  • When an atom looses electrons, it results in the formation of positive ion known as cation.
  • When an atom gains electrons, it results in the formation of negative ion known as anion.

Electronic configuration is defined as the representation of electrons around the nucleus of an atom.

Number of electrons in an atom is determined by the atomic number of that atom.

The element present in Group 2-A and in period 4 is Calcium (Ca)

Electronic configuration of Ca atom:  1s^22s^22p^63s^23p^64s^2

This atom will loose 2 electrons to attain stable electronic configuration similar to Argon element (noble gas)

The electronic configration of Ca^{2+}\text{ ion}=1s^22s^22p^63s^23p^6

Hence, the symbol of the ion formed is Ca^{2+}

Please use the below balanced equation to answer this question.    2H2(g)  +  O2(g)  -&gt;   2H2O(l) How many grams of water wil
Blizzard [7]
At STP (standard temperature and pressure conditions), 1 mol of any gas occupies 22.4 L 
This rule is applied to O₂
22.4 L volume occupied by 1 mol
Therefore 83.4 L occupied by - 1/ 22.4 x 83.4 = 3.72 mol
stoichiometry of O₂ to H₂O is 1:2
then the number of moles of water produced - 3.72 mol x 2= 7.44 mol
mass of water produced - 7.44 mol x 18.01 g/mol = 134.1 g
correct answer is D

Give the percent yield when 162.8 g of CO2 are formed from the reaction of excess amount of C8H18 and with 218.0 grams of O2. (2
katen-ka-za [31]

Percent yield is 23.11 % when 162.8 g of CO2 are formed from the reaction of excess amount of C8H18 and with 218.0 grams of O2.

Explanation:

Balanced equation for the chemical reaction:

2C8H18 + 25O2 → 16CO2 + 18H2O

data given:

CO2 formed (actual yield)  = 162.8 grams

mass of oxygen = 218 grams

16 moles of CO2 formed when 5 moles of oxygen reacted

3.6 moles of CO2 formed when 6.8 moles of oxygen reacted.

In the reaction 16 moles of CO2 will have 44.01 x 16

                                      theoretical yield of CO2    = 704.16 grams

percent yield = \frac{actual yield}{theoritical yield}   x100

         putting the values in the above equation

percent yield = \frac{162.8}{704.16}  x 100

                       = 0.23 x 100

                           = 23.11 %

Percent yield is 23.11 %.
