Why dose a small container have more pressure than a large container of both have the same amount of gas in them
Volgvan
Because in a smaller container, there is less room for the gas to exist. the gas much all push together closer to fit in the smaller container. as gas atoms, they have less room to bounce around. in a bigger container, it has more room to more and is less pressurized

The vertical columns on the periodic table are called groups, how many groups are there on the periodic table?
Kitty [74]
8 groups, 1 to 7 and most people call group 8 group 0 because the noble gases in group 0 have the outer electron shell full, so for example argon has 18 electrons, so it’s structure is 2.8.8 with its outer shell full. Also the number of the last shell defies what group it’s in, for example sodium is in group 1 so it’s structure is 2.8.1. Hope this helps.

Write 2 similarities and 2 differences between the digestive system of a Buffalo and humans
lutik1710 [3]

Answer:

The cow digestive system is not at all like the human digestive system. The main difference between the human digestive system and the cow's animal digestive system is simple: Cows have a stomach that consists of four compartments, commonly referred to as four stomachs. Cows spend the better part of the day eating, swallowing and regurgitating their food, and chewing it again before final digestion. Because a cow's teeth mostly grind their food, cows use their tongues – which is why they are so long – to help them gather and grasp grass for pinching off between their incisors and dental pad at the front part of their mouths.

Calculate the solubility in g/l of lead (ii) fluoride in water at 25 oc if ksp of pbf2 is 4. 1 x 10-8.
Svetlanka [38]

The solubility of Lead(II)Fluoride is 2.17 × 10⁻³ g/L in water at 25°C.

At a specific solution temperature, a solid salt compound can entirely dissolve in pure water up to a predetermined molar solubility limit. The dissociation stoichiometry ensures that the molarities of the constituent ions are proportionate to one another. The saturable nature of the solution causes them to also coexist in a solubility equilibrium with the solid component. At this temperature, a solubility product constant Ksp is calculated using the solubility product of their molarity values.

Lead (II) fluoride has the following solubility equilibrium for its saturated solution:

                   PbF_2(s) ⇄ Pb^2^+ (aq) + 2F^- (aq)

                   K_s_p = [Pb^2^+][F^-]^2

This compound dissociates in a 1:2 ratio of ions. For the compound dissolved in pure water, the Ksp is expressed in terms of the molar solubility "x" as:

K_s_p = (x) (2x)^2\\

K_s_p = 4x^3

Here,

K_s_p= 4.1 × 10^-^8

4.1 × 10⁻⁸ = 4 x³

x³ = 1.025 × 10⁻⁸

x³ = 10.25 × 10⁻⁹

x = 2.17 × 10⁻³ g/L

Therefore, the solubility of Lead(II)Fluoride is 2.17 × 10⁻³ g/L.
