The answer would be B red, violet would be the shortest
The balanced chemical reaction is expressed as:
M + F2 = MF2
To determine the moles of the element fluorine present in the product, we need to determine the moles of the product formed from the reaction and relate this value to the ratio of the elements in MF2. We do as follows:
moles MF2 produced = 0.600 mol M ( 1 mol MF2 / 1 mol M ) = 0.600 mol MF2
molar mass MF2 = 46.8 g MF2 / 0.6 mol MF2 = 78 g/mol
moles MF2 = 46.8 g ( 1 mol / 78 g ) = 0.6 mol
moles F = 0.6 mol MF2 ( 2 mol F / 1 mol MF2 ) = 1.2 moles F
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.
Explanation:
Monosaccharides are simple carbohydrates that cannot be further hydrolyzed to simpler carbohydrates. They contain between three and six carbon atoms per molecule.
Polysaccharides are complex carbohydrates . They are condensation polymers derived from very long chains of monosaccharide units.
Structurally, polysaccharides are made up of repeating units of monosaccharides.
