Answer:
60.01 kJ energy to melt 180g of ice, <em><u>assuming my figure for heat of fusion.</u></em>
<em><u>Explanation:</u></em>
Please check the wording of the question. "6,01 kmoland the molar - mass of ice is 18.02 g/mol" is hard to interpret.
<em><u>I'll assume the heat of fusion of ice is 6.01 kJ/mole</u></em>?
180 grams of solid water (ice) is 180g/(18.02 g/mole) or 9.999 moles, rounded to 3 sig figs to 10 moles.
(10 moles H2O)*(6.01 kJ/mole) = 60.01 kJ energy to melt 180g of ice.
Answer:
Scientists attribute the global warming trend observed since the mid-20th century to the human expansion of the "greenhouse effect" — warming that results when the atmosphere traps heat radiating from Earth toward space.
Certain gases in the atmosphere block heat from escaping. Long-lived gases that remain semi-permanently in the atmosphere and do not respond physically or chemically to changes in temperature are described as "forcing" climate change. Gases, such as water vapor, which respond physically or chemically to changes in temperature are seen as "feedbacks."
Explanation:
Answer:
an atom with a half-filled subshell - hydrogen
an atom with a completely filled outer shell - argon
an atom with its outer electrons occupying a half-filled subshell and a filled subshell- copper
Explanation:
The outermost shell or the valence shell of the atom is the last shell in the atom. Chemical reactions occur at this outer most shell. The number of electrons on the outermost shell of an atom determines the group to which it belongs in the periodic table as well as its chemical properties.
Hydrogen has a half filled 1s sublevel. Only one electron is present in this sublevel.
Let us consider argon
1s2 2s2 2p6 3s2 3p6
The outermost ns and np levels are completely filled. Thus the outermost shell is completely filled.
In the last case; let us look at the electronic configuration of nitrogen;
1s2 2s2 2p3
The outermost 2p subshell is exactly half filled while the 2s sublevel is fully filled. The outermost shell of nitrogen is made up of 2s2 and 2p3 sublevels.
I think the answer is C. An element or compound that cannot be physically separated. Sorry if im wrong.
The ideal gas law states that the relationship between partial pressure and volume is inverse. Additionally, it relates temperature and moles in a direct proportion. The partial pressures of the gases are found to be PN2 = 0.094 atm, PH2 = 0.039 atm, and PNH3 = 0.003 atm in the following reaction at equilibrium at room temperature.
<h3>What is ideal gas law ?</h3>
PV = NkT, where P is a gas's absolute pressure, V is the volume it occupies, N is the quantity of atoms and molecules in the gas, and T is its absolute temperature, is the formula for the ideal gas law.
Equal volumes of two gases with the same temperature and pressure will contain an equal number of molecules, according to the law. The ideal gas law is the result of the union of all these relationships.
