KC7 - Water by Lizbeth https://padlet.com/guzmaliz000/lu0f9jzgpa0l Made with a stroke of good luck en-us 2018-05-15 19:30:44 UTC 2023-02-17 14:37:26 UTC hello@padlet.com 1. Ice is less dense than water because ice has a larger structure and it has a hexagonal shape which helps it float on water. On the other hand, water has a bent shape. guzmaliz000 https://padlet.com/guzmaliz000/lu0f9jzgpa0l/wish/261288174 2018-05-16 16:26:05 UTC https://padlet.com/guzmaliz000/lu0f9jzgpa0l/wish/261288174 3. What are hydrogen bonds? guzmaliz000 https://padlet.com/guzmaliz000/lu0f9jzgpa0l/wish/261291015 Hydrogen bonds are bonds between two molecules. ]]> 2018-05-16 16:32:39 UTC https://padlet.com/guzmaliz000/lu0f9jzgpa0l/wish/261291015 4. Define solvent, solute, and solution guzmaliz000 https://padlet.com/guzmaliz000/lu0f9jzgpa0l/wish/261291683 Solvent is what is making the solute dissolve. Solute is what is dissolving in the solution, and a solution is a mixture of both solvent and solute. ]]> 2018-05-16 16:34:22 UTC https://padlet.com/guzmaliz000/lu0f9jzgpa0l/wish/261291683 5. The solubility of a gas increases, as temperature increases. 6. The solubility of a solid increases, as the temperature increases. guzmaliz000 https://padlet.com/guzmaliz000/lu0f9jzgpa0l/wish/261293927 2018-05-16 16:39:44 UTC https://padlet.com/guzmaliz000/lu0f9jzgpa0l/wish/261293927 7. Three things that increase the rate of solution formation: guzmaliz000 https://padlet.com/guzmaliz000/lu0f9jzgpa0l/wish/261296940 - Agitating the mixture
- Crushing solute
- changing the temperature ]]> 2018-05-16 16:46:15 UTC https://padlet.com/guzmaliz000/lu0f9jzgpa0l/wish/261296940 8. What is the difference between concentrated and dilute solutions? guzmaliz000 https://padlet.com/guzmaliz000/lu0f9jzgpa0l/wish/261352175 A concentrated solution is a solution that has a large amount of solute in it. A dilute solution, there is more solvent than solute in it.]]> 2018-05-16 18:47:36 UTC https://padlet.com/guzmaliz000/lu0f9jzgpa0l/wish/261352175 9. What is the Molarity formula? What is the molarity of a solution containing 10 moles of solute in 2.0 L of solution? guzmaliz000 https://padlet.com/guzmaliz000/lu0f9jzgpa0l/wish/261355033 HINT: Divide moles by Liters
10 M / 2.0 L = 5 M ]]> 2018-05-16 18:55:36 UTC https://padlet.com/guzmaliz000/lu0f9jzgpa0l/wish/261355033 10. What is the Dilution formula? How many mL of 4 M NaBr solution are needed to make 600 mL of 1.0 M NaBr? guzmaliz000 https://padlet.com/guzmaliz000/lu0f9jzgpa0l/wish/261356090 Formula- M1V1 = M2V2 
4 = 1.0 M x 600 mL 
---------------------------- = 150 mL
