- 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
- 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 #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
- 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
- How do you determine the limiting reagent and what is the . . . - Socratic
Here's how you can do that The stoichiometric coefficients that appear in the balanced chemical equation tell you the mole ratios in which the chemical species that take part in the reaction find themselves In your case, you have "PCl"_ (5(s)) + color(red)(4)"H"_ 2"O"_ ((l)) -> "H"_ 3 "PO"_ (4(aq)) + 5 "HCl"_ ((aq)) This tells you that the reaction consumes color(red)(5) moles of water for
- Answers created by Ernest Z. - Socratic
If density is 0 92 g cm–3 at a given temperature, then what is the number of H2O molecules per unit cell? A 9 380 mol sample of nitrogen gas is maintained in a 0 8198 L container at 301 8 K What is the pressure in atm calculated using the van der Waals' equation for N2 gas under these conditions?
