Based on your graph in the Periodic Trends Lab, what is the relationship between atomic radius and ionization energy ?

1 answer:

6 0

As the atomic radius decreases, it becomes harder to remove an electron that is closer to a more positively charged nucleus. ... They experience a weaker attraction to the positive charge of the nucleus. Ionization energy increases from left to right in a period and decreases from top to bottom in a group.

At 27.00 °c a gas has a volume of 6.00 L . What will the volume be at 150.0 °c

mojhsa [17]

T₁ = 27°C = 27 + 273 = 300K, V₁ = 6 L,

T₂ = 150°C = 150 + 273 = 423K, V₂ = ?,

By Charles' Law: V₁/T₁= V₂/T₂

6/300 = V₂/423

423*(6/300) = V₂

8.46 = V₂

Volume at 150°C =8.46 L.

A sample of hydrogen gas at a pressure of 977 mm Hg and a temperature of 32 °C, occupies a volume of 11.3 liters. If the gas is

IrinaK [193]

Answer : The volume of gas sample will be, 9.93 L

Explanation :

Charles' Law : It states that volume of the gas is directly proportional to the temperature of the gas at constant pressure and number of moles of gas.

Mathematically,

$\frac{V_1}{T_1}=\frac{V_2}{T_2}$
