Answer: conversion of ice to steam
Explanation: Endothermic process is one in which energy is absorbed by the system.
Conversion of ice to steam is change of solid phase to gaseous phase, thus energy is required to break the strong inter molecular forces of attraction in solids to convert it into gaseous phase.
Conversion of steam to ice, conversion of steam to water and conversion of water to ice releases energy and are examples of exothermic processes.
<span>Mn's
atomic number is 25 so you have 25 protons and 25 electrons in a
neutral atom. Since no charge is shown, the number of electrons is 25
Ni's atomic number is 28 so you have 28 protons and 28 electrons in a
neutral atom. This one shows a +3 so there are 3 missing electrons, the
number of electrons is 28 - 3 = 25
Cu's atomic number is 29 so you have 29 protons and 29 electrons in a
neutral atom. This one shows a +2 so there are 2 missing electrons, the
number of electrons is 29 - 2 = 27
Ti's atomic number is 22 so you have 22 protons and 22 electrons in a
neutral atom. This one shows a -2 so there are 2 EXTRA electrons, the
number of electrons is 22 + 2 = 24 </span>
the person that is correct is the manufacturer because you cannot make a knife out of Rosewood. Also Rosewood trees are extremely few and far between plus it is illegal to harvest rosewood trees for their lumber since that type of tree genus is also slowly becoming extinct
hope this helps:)
Answer:
Partial pressure of nitrogen gas is 0.98 bar.
Explanation:
According to the Dalton's law, the total pressure of the gas is equal to the sum of the partial pressure of the mixture of gases.
where,
= total pressure = 3.9 bar
= partial pressure of nitrogen gas
= partial pressure of oxygen gas
= partial pressure of argon gases
= Mole fraction of nitrogen gas = 0.25
= Mole fraction of oxygen gas = 0.65
= Mole fraction of argon gases = 0.10
Partial pressure of nitrogen gas :
Partial pressure of oxygen gas :
Partial pressure of argon gas :
