This is an oxidation-reduction (redox) reaction:
2 Mg0 - 4 e- → 2 MgII
(oxidation)
2 O0 + 4 e- → 2 O-II
(reduction)
Answer:
Yes, with change in humidity, enthalpy changes as well.
Explanation:
This can be explained by the given relation:
H = 
where
H = enthalpy (in Btu/lb)
w = specific humidity (lb-water/lb-dry air)
= dry-bulb temperature (in 
)
The above relation clearly explains that if temperature does not vary, enthalpy is in direct proportion with the humidity.
So, any change in humidity results in a corresponding change in the enthalpy.
Carbon dioxide is the atmospheric compound that is
responsible (after it have dissolved in water) for both the general acidity of
normal rainwater and the acidity of much soil. Natural rain water is slightly
acidic because carbon dioxide combined with water in the air forms carbonic
acid, which is a weak acid.
Answer:
Molecule
Explanation:
Because, the combination of bread and veggies make it more likely to be a molecule.
Chemical properties are mainly determined by the number of valence electrons (electrons which can be gained, lost, or shared) in the atom.
