- What is a double replacement reaction? How are they . . . - Socratic
The clue lies in the name itself Double displacement reactions occur when two ionic compounds react, or when an ionic compound reacts with an acid It only occurs in liquids There are 5 types of double displacement reaction, as shown below: Salt + salt = insoluble salt + salt Acid + carbonate = salt + H2O + CO2 Acid + base = salt + H2O Ammonium + hydroxide = salt + H2O + NH3 Acid + sulfite
- What are the names of the two molecules plants need to . . . - Socratic
Two molecules that plants need to absorb to perform photosynthesis are CO2 and H2O
- Question #b4e08 - Socratic
You use the standard enthalpies of formation To calculate the enthalpy change for a reaction, in your case for the combustion of ethane, you can use the standard enthalpies of formation of the species involved in the reaction More specifically, you can calculate the enthalpy change of a reaction by DeltaH_"rxn" = sum(n * DeltaH_"f prod"^@) - sum(m * DeltaH_"f react"^@), where n, m - the
- Question #545aa - Socratic
HA(aq] + OH− (aq] → A− (aq] + H2O(l] It's important to notice that you have 1:1 mole ratios between the weak acid, the strong base, and the conjugate base A− This means that for every one mole of weak acid neutralized by one mole of strong base, one mole of conjugate base is produced
- Question #0760a - Socratic
The pH of the solution is 8 752 !! LONG ANSWER !! Before doing anycalculations, make sure that you have a clear understanding of what goes on here You're titrating acetic acid, "CH"""_3"COOH", a weak acid, with sodium hydroxide, "NaOH", a strong base Right from the start, this tells you that the pH of the solution at the equivalence point will not be equal to 7 That happens because the weak
- Question #a721d - Socratic
H F +H 2O = H 3O+ + F − We can find the concentration of H + or H 3O+ by three ways One is by the ICE table (but this is a 5% rule) and the other is square root which is absolutely correct and the other is Ostwald's law of dillution Let's set up an ICE table mmmmmmmmHF+ H2O ⇌ H3O+m+ mlF- I mol L-1:mmml0 88mmmmm0mmmmml0 C mol L-1:mmml-xmmmmll+xmlmmml+x E mol L-1:mmm0 88- xmmmlxmmmmmllx Ka
- Conjugate Acids and Conjugate Bases - Socratic
Given the following equation: HClO2+H2O--> H2O + ClO2, how would you identify the acid, base, conjugate acid, and conjugate base? How would you identify the conjugate acid-base pairs in the equilibrium equation: HC2H3O2 + H2O --> H3O^+ + C2H3O2^-? What is the conjugate acid of HPO2^2-?
- Question #ab45a - Socratic
Baking soda is NaHCO3 and Vinegar is CH3COOH their reaction in aqueous solution is NaHCO3 +CH3COOH -->CO2 +H2O + CH3COONa Solution will contain sodium acetate and NaHCO3 (if present in excess}
