I need help for question no. 1 and question no. 3

Procedure: Many rocks on Earch form from iodic salts precipitated frem scawater. lonic salts precipoiate 1. Weigh 18g of sodium chloride into the 100mL beaker. When a solution becomes saturated. Solubility is the ability of st sulastance to dissalve in a solution. When a solution is saturated, no more of that substance can be dissolved. 2. Measure 50mL of distilled water using the graduated cylinder and add it to the same beaker. Crystals are special kisds of solids (erystalline solids) that are made up of molecules amanged in a 3. Stir to dissolve the majority of the solid. regular repeating pattern. In some solids (amorphous solids), the arangements of the molocales are random throughout the material. In crystal ine solids, however, the molecules are repeared in exactly the 4. Place the beaker on a hot plate and gently warm the solution. same pattern over and over again throughour the entire material. 5. While the solution is warming, keep stirring the solution until only a few grains of solid are left. Part A: Precipitating Sodiam Cbloride Crystals 6. Carefully pour 25mL (approximately half) of the warm solution into a petri dish. Label the dish Question: and place it in the cupboard as instructed by your teacher. Note: do not disturb once it has been Does the evaporation tate affect the size and shape of sodiurn cbloride crystals formed? put off to the side! 7. Continue heating the remaining 25mL of solution in the beaker until all of the water evaporates. Do not stir the solution! 8. Using the beaker tongs, place the hot beaker off to the side as instructed by your teacher and label the beaker, Careful: this beaker will be very hot! 9. Observe the beaker and the petri dish next class and record your observations. Write down is form of Hypotheis 3.
