Balanced:
2NaOH + CO2 → Na₂CO₃ + H₂O
Explanation:
To balance an equation, the amount of atoms on each side must be <u>equal.</u>
Atom Count on Reactant Side:
Atom Count On Product Side:
As you see, to simply balance the equation, put the 2 in order for the atom count on the reactant side to be equal to the product side. The 2 will add one more of each atom so that its the same as the product side.
Answer:
Such reaction's kinetics is slow.
Explanation:
Hello,
In this case, in quantitative analysis when using sodium it is mandatory to use a glass buret for titrations as it is accurate in terms of measuring volume; however, when sodium hydroxide is in contact with the glass, a very slow rate is present when it reacts with the silicates in the glass, forming sodium silicate, such rate is in the order of 1.3×10⁻⁴ and 4.3 × 10⁻⁴ g/(m² s). In this manner, as an experiment does not take more than 10 minutes (typical titrations) the time is not enough to for a considerable amount of sodium silicate, that is why its use is widely enforced.
Best regards.
Answer:
1) The vapor density of the organic compound is approximately 12.57
2) The relative molar mass (RMM) of the organic compound is approximately 25.14 grams
Explanation:
1) The mass of the balloon filled with dry hydrogen = 35 grams
The mass of the balloon filled with vapor of an organic compound = 440 grams
The vapor density = (Weight of a given volume of gas)/(Weight of equal volume of hydrogen)
The vapor density of the organic compound = (440)/(35) ≈ 12.57
The vapor density of the organic compound ≈ 12.57
2) The relative molar mass (RMM) = 2 × vapor density
The relative molar mass (RMM) of the organic compound = 2 × vapor density of the organic compound
The relative molar mass (RMM) of the organic compound ≈ 2 × 12.57 ≈ 25.14 grams
The relative molar mass (RMM) of the organic compound ≈ 25.14 grams
One mole contains 6.02×10²³
If x mole contains 3.131×10²⁴
x = 3.131×10²⁴
-------------
6.02×10²³
x = 0.52×10²⁴¯²³
x = 0.52×10¹
x = 5.2moles....
Hope this helped...?
