Answer:
hydrologic cycle
Explanation:
the hydrologic cycle is the cycle in wich the natural sequence through which water passes into the atmosphere as water vapor, precipitates to earth in liquid or solid form, and ultimately returns to the atmosphere through evaporation. :)
Answer: Continental climates are classified by whether that fluctuates a lot. Hot summer, Cold winters and Little rainfall are all characteristics of Continental Climates

Answer:
He started factories and mills. He created World's first water- powered mill at Cromford, where he employed more than 200 people. This was just the beginning of the many factories which he would later set up. Because of this, Arkwright was known as the father of the modern industrial factory system........Hope you got it
The question is incorrect, the correct question is;
Which of the following ground-state electron configurations represents the atom that has the
lowest first-ionization energy?
a) 1s2
b) 1s22s2
c) 1s22s22p6
d) 1s22s22p63s23p1
e) 1s22s22p63s23p3
The correct ground state configuration that represents the atom that has the lowest first ionization energy is 1s² 2s² 2p⁶ 3s² 3p¹.
The first ionization energy is the energy required to remove an electron from the outermost shell of an atom.
Ionization energy decreases down the group as number of shells increases but increases across the period as nuclear charge increase.
As the number of shells increases, the degree of shielding or screening decreases it easier to remove the outermost electron.
The elements whose ground state electronic configurations were shown are;
Helium - 1s²
Beryllium - 1s² 2s²
Neon - 1s² 2s² sp⁶
Aluminum - 1s² 2s² 2p⁶ 3s² 3p¹
Phosphorus - 1s² 2s² 2p⁶ 3s² 3p³
Aluminium (1s² 2s² 2p⁶ 3s² 3p¹) is a metal so it has the lowest first ionization energy since metals are highly electropositive.

When the Heat gain or lose = the mass * specific heat * ΔT
and when we have the mass of gold coin= 40 g
and the specific Heat of gold= 0.13 J/g°
and ΔT = (Tf- Ti) = 10°C - 50°C = -40 °C
so by substitution:
∴Heat H = 40 g * 0.13 J/g° * -40
= - 208 J
