Answer: A 59.5 degree celcius
The equation that we will use to solve this problem is :
PV = nRT where:
P is the pressure of gas = 1.8 atm
V is the volume of gas = 18.2 liters
n is the number of moles of gas = 1.2 moles
R is the gas constant = 0.0821
T is the temperature required (calculated in kelvin)
Using these values to substitute in the equation, we find that:
(1.8)(18.2) = (1.2)(0.0821)(T)
T = 332.5 degree kelvin
The last step is to convert the degree kelvin into degree celcius:
T = 332.5 - 273 = 59.5 degree celcius
#1 (As trash, synthetic polymers are not biodegradable)
#2 (Landfills can easily fill up with synthetic polymers)
#4 (Recycling synthetic polymers is costly)
Answer is (4) - 4.
The atomic number of Germanium (Ge) is 32 and it is placed in 14th group of periodic table. In the neutral atom, 32 electrons are present. The electron configuration of Ge is [Ar] 3d¹⁰ 4s² 4p².
Valence electrons are the electrons which are in outer shell of the atom. There are 4 electrons in outer shell of Ge atom at ground state.
