<span>One example of bacteria that live in an extreme environment are the thermophilic species that live in the hot springs of Yellowstone National Park. Thermophilic means heat-loving and the waters in which these bacteria live can rise above 70 degrees Celcius after being heated by lava below the surface. Most life would die at that temperature however some bacteria have evolved to survive the extreme heat.</span>
The Farenheit and Celcius scales can have negative numbers
Noble Gas Cores have following electronic configuration
He = 1s²
Ne = [He] 2s², 2p⁶
Ar = [Ne] 3s², 3p⁶
Kr = [Ar] 4s², 4p⁶
Xe = [Kr] 5s², 5p⁶
Now solving for question elements,
Germanium = Ge = [Ar] 3d¹⁰, 4s², 4p²
Nickle = Ni = [Ar] 3d¹⁰, 4s²
Tunsten = W = [Xe] 4f¹⁴, 5d⁴, 6s²
Titanium = Ti = [Ar] 3d², 4s²
Iron = Fe = [Ar] 3d⁶, 4s²
Zinc = Zn = [Ar] 3d¹⁰, 4s²
The temperature or the average kinetic energy of the molecules
Answer:
0
Explanation:
CaBr₂ is a compound, so it shouldn't have a charge--it's not an ion. But let's check to make sure.
Calcium has a charge of +2.
Bromine has a charge of -1, but there are two Br, so the charge is -2.
+2 + -2 = 0, so the overall charge is 0!
