Answer:
4⁺
Explanation:
Germanium (Ge) has an atomic number of 32 and belongs to group 14 on the periodic table. Germanium has an electronic configuration of [Ar] 3d¹⁰ 4s² 4p². There exist 32 electrons in its neutral atom. In fluorescent lights, germanium is utilized as a component of both alloys and phosphorus.
The electrons in the atom's outer shell are known as its valence electrons.
Thus, at the ground state, the outer shell of the Germanium atom has 4 electrons.
Charles law states that volume of gas is directly proportional to temperature of gas at constant pressure and fixed amount of gas.
V / T = k
where V - volume , T - temperature in Kelvin and k - constant
where parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation
T1 = 25 °C + 273 = 298 K
T2 = 35 °C + 273 = 308 K
substituting values in the equation,
V = 5.17 L
new volume is 5.17 L
I forgot this one, but I learned this in physics class. It had something to do with there being more or less electrons for how ever many photons there is in an atom.
Example: Hydrogen has 1 photon which usually means there is one electron, but when there is more electrons than photons, that is a negative ion. When there's less electrons than photons, that is a positive ion.
hope this helps
1cm = 0.01m
1cm x 172 = 0.01 x 172
172cm = 1.72m
A) 10.0 mL of acetic acid and 200 mL of water
Acetic acid is the solute water is the solvent. Acetic acid dissolves in water.
b) 100.0 mL of water and 5.0 g of sugar
Sugar is the solute while water is the solvent. Sugar dissolves in water.
