Answer:
Reaction 1 = -462.5 kJ/mol
Reaction 2 = -572 kJ/mol
Magnesium combustion = -601.83 kJ/mol
As the electrons are pushed more by the battery, they move faster through the circuit
Explanation:
It is given that the energy change is -162 kJ and work done is -194 kJ. As we know that formula for change in enthalpy is as follows.
dH = dE + W
where, dH = change in enthalpy
dE = change in energy
W = work done
Therefore, the change in enthalpy will be as follows.
dH = dE + W
= -162 kJ + (-194 kJ)
= -356 kJ
As the negative sign indicates heat is being released. Therefore, the reaction is exothermic in nature.
Thus, we can conclude that the change in energy of the gas mixture during the reaction is -356 kJ.
<span>The
flowers undergo photosynthesis so it is expected to release O2. When you zip
the flower in a plastic bag and placed it in the refrigerator, the plastic bag
will shrink in size. The extra air plus the O2 in the back forms gaseous water.
This gaseous water will slowly liquefy and when placed in the fridge, it will
condense to form water solids.</span>
Answer:
Uranus is much bigger than Earth.
Explanation:
it’s about four times bigger than the watch, Uranus is about 31,000 miles in diameter while the earth is only about 7,900 miles.
