I know this a repost, but I didn't get any response and I need some help Examine the reaction mechanism found below: A + B​2​ → AB​2 (slow) AB​2​ + C → AB​2​C (fast) AB​2​C + C → B​2​C​2​ + A (fast) B​2​C​2​ → D + E (fast) a) Write all the reaction interm...

When placed in acid, magnesium metal reacts and forms hydrogen gas: Mg(s) + HCl(aq) --> MgCl2(aq) + H2(g) ΔH = -56.5 kJ/mol If HP denotes the enthalpy of products and Hr denotes the enthalpy of reactants, then: Hp > Hr Hp < Hr Hp = Hr I put Hp > Hr becaus...

HCl is a corrosive colourless gas that dissolves readily in water. Aqueous HCL reacts with NaOH to form water and NaCl. In a simple calorimeter, a 100.00 mL sample of 0.355 mol/L HCl(aq) is mixed with 50.00 mL of excess NaOH(aq). During the reaction, ther...

I know that this is a repost, but I have a question: HCl is a corrosive colourless gas that dissolves readily in water. Aqueous HCL reacts with NaOH to form water and NaCl. In a simple calorimeter, a 100.00 mL sample of 0.355 mol/L HCl(aq) is mixed with 5...

This is a repost, but I have a question. 2.) For the reaction below, initially 3.5 mol of NH​3​ are placed in a 4.0 L reaction chamber. After 3.0 minutes only 1.6 moles of NH​3​ remain. 4 NH​3​(g) + 5 O​2​(g) → 4 NO(g) + 6 H​2​O(g) a. Calculate the averag...

NH​3​ is normally encountered as a gas with a pungent odor. It is formed from hydrogen and nitrogen (equation given below). A chemist pours a mixture of nitrogen gas and hydrogen gas in a 1.0 litre reaction vessel in 1:3 ratio. The equilibrium constant fo...

Estimate the number of years it would take to spend 1 mole (6.022 × 1023 ) of pennies at a rate of 100 million dollars per second. What I got 1909563.67326 years or 10^6, but the answer is 10^7 years approximately. What I did: (6.022 * (10 ^ 23) / 10^2 to...

I was wondering which method would be the best to finding density in a STP question. volume for one mole of gas is 22.4L, I think 1.) d = molarmass/V - I saw this being used on youtube 2.) d = P*MM/RT One mole of which gas has the greatest density at STP?...

A mixture of 5.0 g of Ar and 10.0 g Ne have a total pressure of 2.6 bar. What is the partial pressure of Ar? m(Ar) = 5.0g , M(Ar) = 39.95g/mol m(Ne) =10.0g , M(Ne) = 20.18g/mol n(Ar) = 5.0g/39.95g/mol = 0.125 mol n(Ne) = 10.0g/20.18g/mol = 0.496 mol N(tot...

In an experiment, a sample of CO2 gas was shown to effuse through a pinhole at a rate of 0.033 mol/min (where 1 min = 60 s). Using the same setup, 0.033 mol of a mystery gas effused through the same pinhole in 104 seconds. a) What is the molar mass of the...

What is the question? What do you want me to do with the linear equation? I can't read minds....

7,230 ft / 3 = 2410 yd .....

I have a question, isn't it suppose to be 0.150 L instead of the 0.100 L because " 100.00 mL sample of 0.355 mol/L HCl(aq) is mixed with 50.00 mL of excess NaOH(aq). " or is it just 0.100 L?

I have a question about the rate law, I understand that it is based on the slow step, but I don't understand why is it rate = k [B2] instead of rate = k [A] [B2]? Also my teacher said that I needed to show my steps but I don't know how to since this mecha...

What do you mean by "Remember the negative sign for reactants and positive sign for formation of products." how would this play out (would the outcome of the answer be negative, positive? I'm confused can you give an example and explain please)? Also, Why...

Also if reactants are negative wouldn't that mean that my final answer for my average rate of both NH3 and O2 would be negative as well? example: -1(1/4*0.158 )?

ok so, -1/4 [ΔNH3] / ΔT = positive, since - ( - 0.00264) x 1/4 ? (I turn mins to seconds and divided the M) .... ? Thanks for your first explanation.

oops clicked submit by accident 2) I used an ICE table N​2​(g) + 3 H​2​(g) ⇔ 2 NH​3​(g) I : 1 mol 3 mol 0 C : -x -3x +2x E : 1-x mol 3-3xmol 2x mol since [H2]eq = 0.12 mol/L, then 3-3x = 0.12, therefore x = 0.96 to get [NH3]eq = 2 x 0.96 = 1.92 which one...

Thanks again, I understand your explanation.

I'm big dumb, r2 = 0.033/1.73 = 0.019 was the correct r2 value. what I did was wrong for r2, thus causing me to mess up to final answer.

Then how would "a" affect the volume of gas? I'm confused on that part?
