<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.

When KCl dissolves in water:
34kurt

This dissociation occur because:

O had to bond with H due to the Hydrogen bonding rule, which will form OH~ (Hydroxide).

K is more attracted to Hydroxide than Cl, so it will depart Cl and bond with OH~.

that leaves a H and a Cl, which one has a positive charge and the other has a negative, so they will bond and form Hydrochloric Acid.

The pressure of a gas is 100.0 kPa and its volume is 500.0 mL. If the volume increases to 1,000.0 mL, what is the new pressure o
elena-14-01-66 [18.8K]

Answer:

P_2=50kPa

Explanation:

Hello,

In this case, we can apply the Boyle's law in order to understand the pressure-volume relationship as an inversely proportional relationship relating the initial and the final volume:

P_1V_1=P_2V_2

Next, we compute the final pressure P2:

P_2=\frac{P_1V_1}{V_2}=\frac{100.00kPa*500.0mL}{1000.0mL} \\\\P_2=50kPa

Thus we validate, the higher the volume the lower the pressure.

Best regards.

How many grams of N2 are required to produce 240.0g NH3?
7nadin3 [17]
Balanced equation: N2 + 3H2 ==> 2NH3
moles of NH3 in 240.0 g NH3: 240.0 g x 1 mol/17 g = 14.1 moles
moles N2 needed: 14.1 moles NH3 x 1 mole N2/2 moles NH3 = 7.05 moles N2 needed
grams N2 needed: 7.05 moles x 28 g/mole = 197.4 grams needed :)
