Osmosis is the diffusion of water from an area of high concentration to an area of low concentration. Only water moves in osmosis! The diagrams below show the concentration of water and salt inside the cell and the concentration of water and salt surrounding the cell. Complete the sentences below by comparing the concentration of the water inside the cell and the concentration outside the cell. 1. 95% NaCl 5% H2O 2. 5% NaCl 95% H2O 3. 5% NaCl 95% H2O a. Water will flow (into the cell, out of the cell, in both directions). b. The cell will (shrink, burst, stay the same). a. Water will flow (into the cell, out of the cell, in both directions). b. The cell will (shrink, burst, stay the same). a. Water will flow (into the cell, out of the cell, in both directions). b. The cell will (shrink, burst, stay the same).

The combustion of methane, ch4, releases 890.4kj/mol. that is, when one mole of methane is burned,890.4 kj are given off to the surroundings. this meansthat the products have 890.4 kj less than the reactants.thus, ah for the reaction = - 890.4 kj. a negative symbolforah indicates an exothermic reaction.ch (g) + 20 (g)> co2 (g) + 2 h0 (1); ah = - 890.4 kga) how much energy is given off when 2.00 mol of ch,are burned? b) how much energy is released when 22.4g of ch. areburned?
