Foam cup a has 36 ml of water that contains 2 moles of hcl at 20 degrees celsius. foam cup b has 36 ml of water that contains 2 moles of naoh at 20 degrees celsius. the contents of foam cup a are added to foam cup b and a chemical reaction occurs. the final temperature of the contents of cup b is 31 degrees celsius. i need to calculate the enthalpy change of the reaction. the density of both solutions is 1 g/ml.

A6.10 m nacl can be made by adding [x]g of nacl to a container and making the volume of water up to the 1.00 l line

Which of the following contributes to the structural rigidity of cellulose? adjacent glucose polymers are stabilized by hydrogen bonding. glucose residues are joined by (α1→4) linkages. cellulose is a highly branched molecule. the conformation of the glucose polymer is a coiled structure.

You exhale co2 which is produced during cellular respiration.  co2 combines with the water in your blood's plasma to make up one half of the body's most important buffer pair, carbonic acid.  the more physical activity you engage in, the more co2 your body is producing.  you can see this by putting some of the cabbage indicator in a glass and then blowing bubbles into it through a straw.  can you see a change in the color of the indicator?
