<span>The direction of gas movement is determined by <u>Partial Pressure Difference</u>.

Explanation:
                   According to phenomenon of Diffusion and Effusion gases always move from level of higher concentration to level of lower concentration. In lungs the oxygen moves from external atmosphere to inner body due to difference in partial pressure of Oxygen. Oxygen present in higher quantity outside body moves in through alveoli. And CO</span>₂ present in body moves out through lungs. Same process takes place at tissue level.

An atom of which element has the greatest attraction for the electrons in a bond with a hydrogen atom?
Nadusha1986 [10]
The question can be changed into a new form:
Which element has the most negative electron affinity, or attraction for electrons? halogens have the highest electron affinities, and thus are more attracted to the electrons in the Hydrogen atom than any element in their respective periods.
In this case all the following choices are in the same period, thus Cl or Chlorine is the answer as it is a halogen.

A meteorologist filled a weather balloon with 3.00L of the inert noble gas helium. The balloon's pressure was 765 torr. The ball
yanalaym [24]

Answer:

4.33 L

Explanation:

Step 1: Given data

Initial volume of the balloon (V₁): 3.00 L

Initial pressure of the balloon (P₁): 765 torr

Final  volume of the balloon (V₂): ?

Final pressure of the balloon (P₂): 530 torr

Step 2: Calculate the final volume of the balloon

If we consider Helium to behave as an ideal gas, we can calculate the final volume of the balloon using Boyle's law.

P_1 \times V_1 =  P_2 \times V_2\\V_2 = \frac{P_1 \times V_1}{P_2} = \frac{765torr \times 3.00L}{530torr} = 4.33 L
