Answer:
The Balanced chemical equation of incomplete combustion of methane is : {eq}2CH_{4}(g)+3O_{2}(g)\rightarrow... Part(b): P a r t ( b ) : The incomplete combustion might take place whenever there is a low supply or insufficient supply of oxygen during combustion.
Explanation:
Complete combustion reacts oxygen with a fuel to produce carbon dioxide and water. Eg: 2C8H18 + 25O2→ 18CO2 + 16H20.
According to the second law of thermodynamics, heat energy released by an organism is released into the <span>environment and unusable. This energy is also known as entropy which is defined as the tendency of things to be dispersed and spontaneous. This means that entropy is always random and becomes unavailable energy.</span>
Answer:
The correct answer is "False".
Explanation:
The Elizabethan Era was a period of England's history that corresponds to the reign of Queen Elizabeth I (1558–1603). The Elizabethan Era is considered a golden age of England's history, and part of the Renaissance Era (1300-1600). The Elizabethan view of life changed drastically from the characteristic Medieval view of life. During Medieval times life was seen with a religiously perspective only, while during The Elizabethan Era more people start to view life with a scientific perspective.
<span>The correct answer is option 1. Entropy is the degree of disorderliness in a system. Among the phases, solid has the most ordered structure. Also, at lower temperatures the molecules will have less kinetic energy therefore less motion. Thus, bromine in solid form at 266K has the least entropy.</span>
Answer:
Temperature of boiling point for solution is 101.60°C
Explanation:
This colligative property is boiling point elevation.
ΔT = Kb . m . i
ΔT = T° boiling point for solution - T° boiling point for pure solvent
Kb = The molal boiling point constant
m = molality
i = Van't Hoff factor ( for NaCl i = 2)
NaCl → Na⁺ + Cl⁻
Let's calculate molality (mol of solute in 1kg of solvent)
Mol of salt = Salt mass / Salt Molar mass
Mol of salt = 45 g / 58.45 g/m → 0.769 moles
0.769 moles/0.5 kg = 1.54 m
T° boiling point for solution - 100°C = 0.52°C/m . 1.54m . 2
T° boiling point for solution = (0.52°C/m . 1.54m . 2) + 100°C
T° boiling point for solution = 101.60°C
