Light. ever heard of moon cycles? so d and c are out of the question. and although almost non-existent, the moon does have gravity. only thing the moon doesn't have is light emitting from itself
Answer: normal fault
A fault refers to a planar or curved fracture in the rocks of the Earth crust, in which compressional or tensional forces results in the displacement of the rock on the opposite side of the fracture. Fault may vary in the length of the fracture. A normal fault is a fault in which the hanging wall of the rock moves downward to the footwall. It occurs when the two blocks of rock are separated apart by the tensional forces.
On the basis of the above information, the normal fault is the fault that should be found by the geologists in the rock.
Explanation:
An element just has one-type atoms/atom (e.g. O2). Meanwhile, a compound is a variety of atoms (e.g. H2O).
Answer:
HCl
Explanation:
Volume = 25L
Temperature = 25.0 oC + 273 = 298 K (Converting to kelvin units)
Pressure = 1.2 atm
Mass of gas = 44.7g
Formular of gas = HX
To solve this, we have to know the identity of X. One qay to do that is by obtaining the molecular mass of the compound.
To get the molar mass, we need the number of mole.
Using the ideal gas equation;
PV = nRT
where R = gas constant = 0.082 057 L atm K−1 mol−1
n = PV / RT
n = 1.2 * 25 / 0.082 057 * 298
n = 30 / 24.45
n = 1.227 mol
The relationship between number of moles and molar mass is given as;
Nummber f moles = mass / molar mass
Molar mass = mass / Number of moles
Molar mass = 44.7 / 1.227
Molar mass = 36.43 g/mol
Molar mass of gas X = Molar mass of H + Molar mass of X
36.43 = 1 + X
X = 36.43 - 1 = 35.43
Chlorine is the only element with molar mass approximate to 35.43
Hence X = Cl
The chemical formular = HCl
