  • Please can someone help and balance this equation [Ni(H2O)6 . . . - Socratic
    Well, the first is a chemical equation, the which I am competent to address We make the hexa-ammine nickel(II) complex [Ni(OH_2)_6]^(2+) + 6NH_3(aq) rarr [Ni(NH_3)_6]^(2+) + 6H_2O(l) And the second is a nucular reaction the which DOES NOT conserve mass ""^235U + "neutron" rarr ""^140Xe + ""^94Sr + "2 neutrons " And please compare this with your text, and notes because I am no
  • What is the percent yield of O_2 if 10. 2 g of O_2 is . . . - Socratic
    %Yield=67 5% The percent yield can be calculated by: %Yield=("Actual Yield") ("Theoretical Yield")xx100% The actual yield of oxygen is given and it is 10 2g We will need to find the theoretical yield The decomposition reaction of water can be written as: 2H_2O(l)->2H_2(g)+O_2(g) To find the theoretical yield of oxygen we will use dimensional analysis: ?g O_2=underbrace(17 0gH_2Oxx(1molH_2O
  • How many moles of water (H2O) are present in a beaker . . . - Socratic
    How many moles of water (H2O) are present in a beaker containing 45 9 g H2O? Chemistry 1 Answer anor277
  • Question #d1319 - Socratic
    K_a = 1 7 * 10^(-4) Methanoic acid is a weak acid, which implies that it will only partially ionize in aqueous solution to produce hydronium cations, "H"_3"O"^(+), and methanoate anions, "HCOO"^(-) The ionization equilibrium can be written as "HCOOH"_ ((aq)) + "H"_ 2"O"_ ((l)) rightleftharpoons "HCOO"_ ((aq))^(-) + "H"_ 3"O"_ ((aq))^(+) Now, notice that every mole of methanoic acid that
  • Site Map - Dipole-Dipole Interactions Questions and Videos - Socratic
    Which of the following compounds exhibits only dispersion and dipole-dipole intermolecular interactions ? A) HBr B) CO2 C) H2O D) N2 Question #91f53 How come an atom cannot have a permanent dipole moment? Question #dbcca Why are homonuclear diatomic molecules non-polar?
  • How do I balance the chemical equation for the reaction between . . .
    "3KOH"+"H"_3"PO"_4"rarr"K"_3"PO"_4"+3H"_2"O" "KOH"+"H"_3"PO"_4"rarr"K"_3"PO"_4"+H"_2"O" There is one phosphate anion "PO"_4^(3-)" on both sides, so for the moment we can ignore it There are 3 "K" atoms on the right side of the equation, so we can try putting a coefficient of 3 in front of the "KOH" on the left side of the equation "3KOH"+"H"_3"PO"_4"rarr"K"_3"PO"_4"+H"_2"O" We now have 6 "H
  • Question #6b9a2 - Socratic
    "a " 0 02 "mol" "b " 0 89 "g" In order to answer these questions we first need to know the equation representing this chemical reaction
  • How do grignard reagents react with water? - Socratic
    Irreversibly This is sometimes exploited by chemists The carbanionic nucleophile reacts with the electrophilic proton on the water molecule: R-MgX + H_2O rarr R-H + MgXOHdarr The reaction is irreversible, but it does have some synthetic utility if you want to label an hydorcarbyl chain with an isotope of hydrogen, ""^2H or ""^3H, simply by using heavy or tritiated water
  • Site Map - Thermochemistry of Phase Changes Questions and Videos - Socratic
    How many kJ are required to heat 45 0 g of H2O at 25 0°C and then boil it all away? What amount of heat is needed to raise 27 0 g of water from 10 0 °C to 90 0 °C? How can I calculate thermochemistry equations for phase changes?
  • Could a buffered solution be made by mixing aqueous . . . - Socratic
    No, and you've also got two definitions mixed up Two things: The whole point of a buffer is to resist pH change You're not going to do that with two things that dissociate completely "HCl" and "NaOH" are not conjugates of each other What is the definition of a conjugate base or acid? What do they differ by? Any strong acid has a terrible conjugate base that does almost literally nothing in
