Explanation:
One common property with all halogens in group 7 is that they are all non-metals.
Fluorine, chlorine, Bromine and Iodine are classified as non-metallic elements and they have a high electronegativity.
- In chemical reactions, they are very reactive because they require just one electron to complete their octet configuration and be isoelectronic with noble gases.
The most prominent observation from halogens is that they all non-metallic in nature.
Answer:
The magnitude of the net force F₁₂₀ on the lid when the air inside the cooker has been heated to 120 °C is 
Explanation:
Here we have
Initial temperature of air T₁ = 20 °C = 293.15 K
Final temperature of air T₁ = 120 °C = 393.15 K
Initial pressure P₁ = 1 atm = 101325 Pa
Final pressure P₂ = Required
Area = A
Therefore we have for the pressure cooker, the volume is constant that is does not change
By Chales law
P₁/T₁ = P₂/T₂
P₂ = T₂×P₁/T₁ = 393.15 K× (101325 Pa/293.15 K) = 135,889.22 Pa
∴ P₂ = 135.88922 KPa = 135.9 kPa
Where Force = 
we have
Force = 
.
Answer:
P V = N R T ideal gas equation
P2 / P1 = T2 / T1 where the other variables are constant
P2 = (T2 / T1) * P1 = (313 / 293) * 40 psi = 42.7 psi
10+15+5+20=50ohms
5 ohms is a tenth of the total resistance.
226/10= 22.6 volts across 5 ohm resistor
Answer:
Hey there.
Your answer (this is my guess) should be layers. I think this because the change in density of the layers from the inner core of the earth to its crust affects the speed of seismic waves.
So if the speed of seismic waves changed you can most likely deduce that the earth has layers.
If i am correct i would really like a brainly.
