Answer:
a. True
Explanation:
The bond angle for methane is the angle determined by two consecutive hydrogen atoms and the central carbon atom.
Methane, a tetrahedron has the structural formula:
H
|
H - C - H
|
H Methane, CH4
The bond angle is the angle between the H-C-H atoms and is 109.5degrees.
All moving objects have kinetic energy.
Kinetic energy is the energy of motion, therefore if an object is moving it has kinetic energy.
The equilibrium shifts to the right to favor the formation of the products. Le Chatelier's principle states that a system will do what it takes to negate any changes made or added to it.
The answer would be lower because the higher the pH is he lower the number is
The answer to question 8 is
Ethanol's Molar Heat of Combustion. ... Heats of combustion are quoted as positive numbers while the enthalpy changes of combustion reactions (ΔH) are quoted as negative numbers, as combustion reactions are always exothermic. Heats of combustion are typically stated in kilojoules per mole (kJ/mol. or kJ mol. -1).
