The C2-C3 single bond in butane freely rotates at room temperature, see equation (1) below. In contrast, the C2-C3 single bond i

n the butenyl cation, equation (2), has a high energy barrier for rotation and does not rotate at room temperature. Use structures to explain why the C2-C3 rotational barrier in butenyl cation is so high.

Answer: Rotation occurs at single bonds that are sigma bonds. Rotational barrier is the amount of  activation energy required to covert rotamer to another by rotation that occurs around the sigma bond(C-C single bond). Due to the presence of steric hindrance that is the nonbonding interaction effects the reactivity of ions and molecules, activation energy increases. So the rotational barrier in butenyl cation is high.

What is the total number of protons in an atom with the electron configuration 2-8-18-32-18-1.
svp [43]

The total number of protons in this atom is 79 because an atomic number of an element is equal to the number of protons. Here, the atomic number is 79 after adding the given electronic configuration.

What are Protons?

Every atom has a proton, a subatomic particle, in its nucleus. The particle possesses an electrical charge that is positive and opposite to the electrons.

What is Atom?

A nucleus plus one or more electrons bound to the nucleus make up an atom. The quantity of protons or electrons in an element's atom determines how different it is from other similar elements. The atomic number of an element, which serves as its primary identification, is the sum of its protons or electrons.

What is Electronic configuration?

The arrangement of electrons in atomic or molecular orbitals within an atom, molecule, or other physical structure is known as the electron configuration.

Hence, the total number of protons in this atom is 79, after adding 2 + 8 + 18 + 32 + 18 + 1.

A student made a sketch of a potential energy diagram to represent a reaction with a -^H
OLga [1]

Answer: It’s correct because it’s showing an exothermic reaction. x is the reactants and y is the products.

Explanation: -ΔH means the reaction is exothermic and releasing heat. This lowers the potential energy.

Water is placed in a graduated cylinder and the volume is recorded as 43.5 mL. A homogeneous sample of metal pellets with a mass
Ipatiy [6.2K]

Answer:

1.8g

Explanation:

Initial volume = 43.5ml

Final volume = 49.4ml

Mass = 10.88g

Density = ?

Volume = Final volume - initial volume

= 49.4 - 43.5

= 5.9ml

Density = Mass/volume

Density = 10.88/5.9

= 1.8g/ml

The combustion reaction of propane is described by the reaction. c3h8 5o2 → 4h2o 3co2. how many moles of o2 are required to gene
dmitriy555 [2]
C₃H₈   +   5 O₂   →   4 H₂O   +   3 CO₂

mole ratio based on balance equation of  O₂   :   CO₂ i  s    5  :  3
                      C₃H₈   +   5 O₂   →   4 H₂O   +   3 CO₂

∴ if moles of CO₂  =  3 moles
  
then moles of O₂  = (3 moles ÷ 3) × 5
                             
                             =  <span>5 moles   </span>
