Suppose you have a box with red chairs and another with blue tables, both are made of smaller lego bricks. You pour the content of both boxes into a larger box and shake the box. You notice that, in the end: 1) Red and blue pieces became more evenly distributed throughout the box. II) Many chairs and tables had pieces of them break off. III) Sometimes, pieces stuck to each other forming all sorts of shapes, some containing both red and blue pieces. Are the changes described in items (I), (II) and (III), best compared to changes in entropy, enthalpy, or both? (1) Entropy only; (II) Entropy only; (III) Entropy only O (1) Entropy only; (II) Enthalpy only; (III) Entropy only O (1) Entropy only; (II) Both; (III) Both O (1) Both; (II) Both; (III) Both (1) Entropy only; (II) Enthalpy only; (III) Enthalpy only

Given for this problem: Element R has a molecular weight of 72.00   Note!! Element R is not a real element. Element A has a molecular weight of 22.00   Note!! Element A is not a real element. Given the reaction  2R + 3A  =   R2A3 q = mass X specific heat X (Tfinal - Tinitial) specific heat of water is 4.184 J/g oC % Yield = (actual/theoretical) X 100 Given this hypothetical activity series: Li > Na > Mg > A > Al > Zn > H > Cu > R > Ag > Pt Given the reaction 2R + 3A  =  R2A3   Please Read Carefully.  It is R2A3 !!!  How many grams of element R would it take to get 400 grams of R2A3.  Read carefully, it is R2A3 !!

Here is the graph below pls answer the question. thanks The graphs in this experiment are for nitrogen gas, however, they do not have labels that identify the type of gas being represented. Would the curves for a more massive gas, such as CO2, look different? O No. The molar mass of a gas does not affect the shape of the kinetic energy distribution. O Yes, since CO2 has a larger molar mass, we'd expect the curve to shift towards left, indicating that a larger fraction of molecules have low kinetic energies. O Yes, since CO2 has a larger molar mass, we'd expect the distribution to shift towards the right, indicating a larger fraction of the molecules have high kinetic energies.
