H2 reacts with the halogens (X2) according to the reaction: H2(g)+X2(g)⇌2HX(g) where X2 can be Cl2, Br2, or I2. Reactant/Product ΔH∘f(kJ/mol) ΔS∘f(J/mol⋅K) H2(g) 0 130.7 Cl2(g) 0 223.1 HCl(g) -92.3 186.9 Br2(g) 30.9 245.5 HBr(g) -36.3 198.7 I2(g) 62.42 260.69 HI(g) 26.5 206.6 Calculate ΔH∘ for the reaction between hydrogen and Br2.

did anyone actually do this? like if anyone has submitted this i rly need .

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.

cytokinesis is the splitting of a cell membrane to form 2 identical daughter cells. it's similar to mitosis as both cells have identical copies of dna and cytokinesis is a step in the mitotic cycle.

they vary. it used to be meat, grain, bread, candy, beverages, donuts, and fruits/vegetables. now they added exercise in.
