Answer:
boiling point and melting point.
Answer:
Most of the atom is empty space. The rest consists of a positively charged nucleus of protons and neutrons surrounded by a cloud of negatively charged electrons. The nucleus is small and dense compared with the electrons, which are the lightest charged particles in nature.
Answer:
2.14 moles of H₂O₂ are required
Explanation:
Given data:
Number of moles of H₂O₂ required = ?
Number of moles of N₂H₄ available = 1.07 mol
Solution:
Chemical equation:
N₂H₄ + 2H₂O₂ → N₂ + 4H₂O
now we will compare the moles of H₂O₂ and N₂H₄
N₂H₄ : H₂O₂
1 : 2
1.07 : 2×1.07 = 2.14 mol
Answer:
Work = Path function.
Energy = State function.
Distance traveled = Path function.
Enthalpy = State function.
Heat = Path function.
Explanation:
Hello,
At first, a state function is a property whose value does not depend on the path taken to reach that specific function or value, as in this case, energy and enthalpy.
On the other hand, path functions are functions that depend on the path taken to reach that specific value, as in this case, work, distance traveled and heat since different paths will provide different values for each one of them.
Best regards.
