Balancing Chemical Equations - Chemistry - Socratic
2 H 2 + O2 -> 2 H 2O. OR. H-H + H-H + O=O -> H-O-H + H-O-H. There are 4H atoms before and after the reaction (each with a mass of 1 amu) There are 2O atoms before and after the reaction (each with a mass of 16 amu) The total mass before the reaction is 4x1 + 2x16 = 36amu. The total mass after the reaction is 4x1 + 2x16 = 36amu.
Ksp - Chemistry - Socratic
In a saturated solution the solid is in equilibrium with its ions e.g : CaCO3(s) ⇌ Ca2+ (aq) + CO2− 3(aq) The expression for Ksp is: Ksp = [Ca2+ (aq)][CO2− 3(aq)] We don't include the concentration of the solid as this is assumed constant. So if we know the concentration of the ions you can get Ksp at that particular temperature.
What happens when you combine silver nitrate with sodium …
2017年4月3日 · Combining silver nitrate AgN O3 with sodium chloride N aCl is a double replacement reaction. The positive and negative ions trade places. See the chemical reaction below. Ag+(aq) +N O− 3 (aq) +N a+(aq) + Cl−(aq) → AgCl(s) + N a+(aq) + N O− 3 (aq) The sodium ion (N a+) and the nitrate ion (N O− 3) do not react and stay in the solution ...

Double Replacement Reactions - Chemistry - Socratic
This is a double replacement reaction, because the silver ion and the sodium ion have exchanged partners. It is also a precipitation reaction, because the silver ion and the chloride ion are removed from the solution as solid silver chloride. Here is a video which shows another example of a double replacement (precipitation) reaction.
What is the chemical equation for aqueous sodium chloride
2016年11月8日 · AgNO_3(aq) + NaCl(aq) rarr NaNO_3(aq) + AgCl(s)darr This reaction is commonly used to illustrate basic solubility rules, and solubility equilibria. All nitrates are soluble, hence silver nitrate is soluble; and all halides are soluble, EXCEPT for AgX, PbX_2, and Hg_2X_2. Thus silver nitrate is soluble, but silver chloride precipitates from solution as a curdy …
What is the K_(sp) for silver chloride? - Socratic
2018年2月24日 · By definition, the solubility product constant for silver chloride is equal to. Ksp = [Ag+] ⋅ [Cl−] Plug in your values to find--I'll leave the value without added units! Ksp = (1.326810−5) ⋅ (1.326 ⋅ 10−5) = 1.758 ⋅ 10−10. Based on the values you have for the volume of water, the answer should be rounded to one significant ...
What is a balanced equation for the following reaction: silver ...
2017年5月15日 · 2Ag + Cl_2 -> 2AgCl Silver forms an Ag^(+) ion and Chlorine gains an electron to form a Cl^(-) ion. However, Chlorine exists as diatomic molecules, meaning it goes round in pairs of two chlorine atoms, so the chlorine as a reactant would be Cl_2, and thus we need 2 Ag atoms to balance it out.
Why will no salt form in the reaction between AgCl and HNO3?
2018年2月18日 · Here, H N O3 is an acid. It is nitric acid, in fact. However, AgCl, or silver chloride, is not a base, and so does not form a salt. Surprisingly, AgCl itself is a salt, and a product of a neutralisation reaction: that between hydrochloric acid and silver hydroxide. No salt will form because the position of equilibrium lies far to the left.
