Hello there,
The moment the tablet<span> starts </span>dissolving<span> a chemical reaction occurs that </span>Some<span> factors can change how quickly the carbon dioxide gas is produced. Stir the ice cubes in the jar for about a </span>minute<span> so that the temperature evens out.
</span>
he tablets<span> effervesce, or fizz, when </span>dropped into water. Some<span> factors that influence the speed of a chemical reaction are: (1) Pour the </span>water<span> into 3 separate </span>glass<span> beakers.
</span>
When the solid<span> material has </span>completely<span> disappeared and the bubbles have vaneished. Stir for a </span>minute<span> or two so that it mixes in.
</span>
Hope this helped
Phosphoric acid forms three classes of salts corresponding to replacement of one, two, or three hydrogen atoms. Among the important phosphate salts are: sodium dihydrogen phosphate (NaH2PO4), used for control of hydrogen ion concentration (acidity) of solutions; disodium hydrogen phosphate (Na2HPO4), used in water treatment as a precipitant for highly charged metal cations; trisodium phosphate (Na3PO4), used in soaps and detergents; calcium dihydrogen phosphate or calcium superphosphate (Ca[H2PO4]2), a major fertilizer ingredient; calcium monohydrogen phosphate (CaHPO4), used as a conditioning agent for salts and sugars.
Answer:
The value of Kc for the reaction is 3.24
Explanation:
A reversible chemical reaction, indicated by a double arrow, occurs in both directions: reagents transforming into products (
direct reaction) and products transforming back into reagents (inverse reaction)
Chemical Equilibrium is the state in which direct and indirect reactions have the same reaction rate. Then taking into account the rate constant of a direct reaction and its inverse the chemical constant Kc is defined.
Being:
aA + bB ⇔ cC + dD
where a, b, c and d are the stoichiometric coefficients, the equilibrium constant with the following equation:
Kc is equal to the multiplication of the concentrations of the products raised to their stoichiometric coefficients divided by the multiplication of the concentrations of the reagents also raised to their stoichiometric coefficients.
Then, in the reaction 3A(g) + 2B(g) ⇔ 2C(g), the constant Kc is:
where:
- [A]= 0.855 M
- [B]= 1.23 M
- [C]= 1.75 M
Replacing:
Solving you get:
Kc=3.24
<u><em>The value of Kc for the reaction is 3.24</em></u>
