At what pressure will 36 grams of CO2 occupy 28.9 L at standard temperature

C₃H₈  + 5O₂  --> 3CO₂  + 4 H₂O

Using the above reaction, calculate how many grams of H₂O will be made if 195.0 g of O₂ is reacted?

N 2 react to produce magnesium nitride , Mg 3 N 2 If the reaction is done in a closed system , what will be the mass of the product ? evidence and A 39 combination of Magnesium Mg and nitrogen gas reasoning to back up your claim

what is the number of molecules present in 0.062 mol of acetic acid, CH₃COOH

The cell represented below was set up under standard conditions.

Pt|Fe²⁺(aq), Fe³⁺(aq)||Tl³⁺ (aq),Tl⁺ (aq)|Pt Cell e.m.f. = + 0.48 V

(i) Deduce the standard electrode potential for the following half-reaction.

Tl³⁺(aq) + 2e^– → Tl⁺ (aq)

(ii) Write an equation for the spontaneous cell reaction.

Use the data given below, where appropriate, to answer the questions which follow.

Standard electrode potentials in acid solution E /V

Mg²⁺ (aq) + 2e^– → Mg(s) –2.37

Zn²⁺ (aq) + 2e^– → Zn(s) –0.76

Sn⁴⁺(aq) + 2e^– → Sn²⁺(aq) +0.15

VO²⁺(aq) + 2H⁺ (aq) + e^– → V³⁺(aq) + H₂O(l) +0.34

VO⁺₂(aq) + 2H⁺(aq) + e^– → VO²⁺(aq) + H₂O(l) +1.02

Ce⁴⁺(aq) + e^– → Ce³⁺(aq) +1.70

(a) Give the components of the standard reference electrode used in determining the standard

electrode potentials above. State the conditions under which this standard reference

electrode has a potential of 0.00 V.
