Answer:
Protons= 17, Electrons= 17, Neutrons= 18
Explanation:
The atomic number (Z) corresponds to the number of electrons that is equal to the number of protons (17). The mass number (A) corresponds to the sum of protons and neutrons present in the nucleus (35). Therefore, we calculate the number of neutrons: 35-17 = 18
A.) slower, low is the answer your answer let me know if I got it right 99.9% I’m right
The volume of one mole of gas is 22.4 liters at 0 °C and 760 Torr. The volume of the given condition can be calculated using:
(PV)/T = constant
(P₁V₁)/T₁ = (P₂V₂)/T₂
(760 * 22.4)/273 = (792 * V₂) / 321.7
V₂ = 25.3 Liters
The Mr of He = 4
The Mr of Ne = 20
Density of He = 4/25.3 = 0.1581 g/L
Density of Ne = 20/25.3 = 0.7905 g/L
Let x be the fraction of Ne
1 - x is the fraction of He
avg density = sum[(mole fraction * Mr)/V]
0.6048 = (20x + 4(1 - x))/25.3
x = 0.70
Ions are neither polar or non-polar because their are no molecules!!
