It’s gonna be water and wind after many years of harsh winds and water the rock will slowly start to break or even become smooth ! That’s why you might find those at the lake ! so c!
Explanation:
Fluorine: F-
Aluminium: Al3+
Bromine: Br-
3F2 + 2AlBr3 => 3Br2 + 2AlF3
In chemistry Electronic configuration, also called electronic structure, the arrangement of electrons in energy levels around an atomic nucleus. According to the older shell atomic model, electrons occupy several levels from the first shell nearest the nucleus, K, through the seventh shell, Q, farthest from the nucleus.
Hopefully this helps!!
Answer:
0.0069 mol
Explanation:
Given data:
Temperature = 25°C
Volume of gas = 0.044 L
Pressure of gas = 3.81 atm
Number of moles of gas = ?
Solution:
The given problem will be solve by using general gas equation,
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
Now we will convert the temperature.
25+273 = 298 K
3.81 atm × 0.044 L = n × 0.0821 atm.L/ mol.K × 298 K
0.17 atm.L = n ×24.47 atm.L/ mol
n = 0.17 atm.L/24.47 atm.L/ mol
n = 0.0069 mol
