The diagrams show gases that are stored in two separate but similar containers. 2 identical containers have gas particles, represented by small balls with arrows representing movement in random directions. The Gas 1 container has many fewer balls than the Gas 2 container. If both gases are at the same temperature, which one has the greater pressure? A. gas 1 because the particles are moving much faster B. gas 1 because it has fewer particles that are close together C. gas 2 because it has more particles that are colliding D. gas 2 because the particles have more space between them 83 / 84 82 of 84 Answered

Answer asap need by wednesday morning explain how a buffer works, using an ethanoic acid/sodium ethanoate system including how the system resists changes in ph upon addition of a small amount of base and upon addition of a small amount of acid respectively. include the following calculations in your i. calculate the ph of a solution made by mixing 25cm3 0.1m ch3cooh and 40cm3 0.1m ch3coo-na+. [ka = 1.74 x 10-5 m] ii. calculate the ph following the addition of a 10cm3 portion of 0.08 m naoh to 500cm3 of this buffer solution. iii. calculate the ph following the addition of a 10cm3 portion of 0.08 m hcl to 200cm3 of the original buffer solution.
