Although the volume is set, the shape and structure of the cup is up to you (for example, your cup can be tall and skinny with a handle or short and wide without a handle)

Think about the cup's intended use, and determine at least two criteria for the shape of the cup and the location of its two compartments.

Part C

Constraints are the limits that we place on a design. Time, materials, or money may be in short supply. Some designs may also be limited by how the product gets used. List at least one constraint on the drinking cup design.

Choose all the answers that apply. ionic compounds dissolve easily in water do not dissolve in water have low melting points have high melting points conduct electricity when melted

There are two steps in the usual industrial preparation of acrylic acid, the immediate precursor of several useful plastics. in the first step, calcium carbide and water react to form acetylene and calcium hydroxide: cac2 (s) + 2h2o (g) → c2h2 (g) + caoh2 (s) =δh−414.kj in the second step, acetylene, carbon dioxide and water react to form acrylic acid: 6c2h2 (g) + 3co2 (g) + 4h2o (g) → 5ch2chco2h (g) =δh132.kj calculate the net change in enthalpy for the formation of one mole of acrylic acid from calcium carbide, water and carbon dioxide from these reactions. round your answer to the nearest kj .
