First, we need to get the moles of Cl2 ( chlorine)
we can use the ideal gas formula to get n ( moles of gas) :
PV = nRT
when p is the pressure = 1.3 atm
and V is the volume = 25.8 L
R is the constant of the ideal gas = 8.314
T temperature in Kelvin = 293
∴ n = PV / RT
= 1.3 * 25.8 / 8.314* 293
= 0.0138 moles
according to the reaction equation:
2Na(s) +Cl2 → 2 NaCl
we can see from the balanced equation that the molar ration between Na & Cl2 = 2: 1
∴ moles of Na = moles of Cl2 / 2
= 0.0138 / 2
= 0.0069 moles
now, we have the moles of Na and by using the molar mass of Na = 22.99 g/mol
∴ Mass of Na = moles of Na * molar mass
= 0.0069 moles * 22.99
= 0.1586 g
Using the formula 2n² put in the value of n which is 4
the answer is 2×4² which is 2×16
The answer is 32.
this is the maximum no of electron acceptable into the electron shell.
Please mark me as brainliest.
It is simple. A plant structure have different parts but both structures carry around an Cell Wall.
The species bonds with the most ionic character is the compound with elements that develop the higher electronegativity difference between each other.
the most ionic character had maximum EN.
EN is max for SiO2
hope this help
