Answer:
B. False
Explanation:
the reaction is
H₂0 + O₂ = H₂O
as addition of oxygen means burning in the system which means heating or energy is necessary for the reactants. SO the reaction is spontaneous and exothermic .
As according to second law of thermodynamics
the change in enthalpy is greater than or equal to zero when the reaction is spontaneous, so enthalpy will increase in the above reaction.
H2 burning in O2 to form H2O (l) is an example of a system where the entropy of the universe increases.
A chemical reaction that removes electrons from an atom is called "O<span>xidation".
The term came from late 18th century from French.
When the electrons are removed from an atom it increase its valence.</span>
Answer:
Explanation:Matter can be described by certain measurements. They include length, area, and volume. Length tells you the number of units that fit along one edge on an object. In the metric system, units of length are based on the meter.
<span> It is a type of potential </span>energy<span> that can be defined in two ways. In one way, the </span>lattice energy<span> is the </span>energy<span> required to break apart an ionic solid and convert its component atoms into gaseous ions</span>
A.He
because He 's molecular weight is small than each other
