What is a neat liquid? + Example - Socratic
2017年6月27日 · A pure substance (element or compound) that is in the liquid phase. A liquid can be described as "neat" if it is a pure substance (a single compound, or a single element) that happens to be in the liquid phase. For example, pure anhydrous ethanol is a "neat liquid". Pure benzene, with nothing else added to it, is also a "neat liquid", as is pure water. The following, however, are not "neat ...
Laws of Proportions - Chemistry - Socratic
2015年6月19日 · In water, for example, the mass of oxygen must always have the same ratio to the mass of hydrogen (mass ratio is #"O:H = 7.94:1"#). To tell if compounds containing the same elements are the same or different, we can determine the ratios of their masses. EXAMPLE. Compound 1 contains 15.0 g of hydrogen and 120.0 g oxygen.

Ionic Compounds - Chemistry - Socratic
Ionic compounds are compounds formed between a metal and nonmetal which have a crystalline lattice structure. They can conduct electricity and are usually highly water soluble. The ionic compounds can form one cohesive compound, such as Potassium Fluoride, or form more complex polyatomic ionic compounds, such as Calcium Carbonate.
How do you calculate the energy needed to heat water?
2016年12月7日 · It depends on how much water you have, and to what temperature you want to raise it to. The equation for the amount of thermal energy needed to produce a certain temperature change is as follows: q = cmDeltaT Where: q is the amount of thermal energy c is the heat capacity of water (~~ 4.184 J/g^oC) DeltaT is the change in temperature. So, how much thermal energy you need is dependent on ...
Molality - Chemistry - Socratic
The concentration of a water solution of #NaCl# is 2.48 m, and it contains 806 g of water. How much #NaCl# is in the solution? What is the molality of a solution that contains 31.0 g #HCl# in 5.00 kg water?
Percent Yield - Chemistry - Socratic
So, let's say you want to do an experiment in the lab. You want to measure how much water is produced when 12.0 g of glucose (#C_6H_12O_6#) is burned with enough oxygen. #C_6H_12O_6 + 6O_2 -> 6CO_2 + 6H_2O# Since you have a #1:6# mole ratio between glucose and water, you can determine how much water you would get by
Ksp - Chemistry - Socratic
The magnitude of #K_(sp)# directly indicates the solubility of the salt in water, since #K_(sp)# is derived from the concentrations of ions in equilibrium reactions. Thus, higher concentrations of ions mean greater solubility of the salt.
How can I calculate freezing point depression of Water?
2014年5月2日 · Kf = freezing point depression constant of water (-1.86°C/m) m = the molality of the solution (mol solute/kg solvent) i = the number of dissolved particles the solute produces. The i for any molecular compound is 1. For ionic compounds, you'll need to know how many ions make up a formula unit. NaCl breaks into two ions so its i value is 2
Factors Affecting Solubility - Chemistry - Socratic
The solubility of carbon dioxide in water is 0.161 g #CO_2# in 100 mL of water at 20°C and 1.00 atm. A soft drink is carbonated with carbon dioxide gas at 5.50 atm pressure. What is the solubility of carbon dioxide in water at this pressure?
