Based on the nature of chemical equilibrium, the system reached equilibrium first at the time T2.

<h3>What is chemical equilibrium?</h3>

Chemical equilibrium refers to the state of a reversible chemical reaction in which the rate of forward reaction for the the formation is equal to the rate of backward reaction for the formation of reactants.

In the table of the decomposition reaction given above, the system reached equilibrium first at the time T2 when the concentration of the reactant and products were the same.

Dilute solutions of NaHCO3 are sometimes used in treating acid burns.
Temka [501]

Answer:

We need 375 milliliters of 0.100 M NaHCO3 solution

Explanation:

Step 1: Data given

Initial molarity NaHCO3 = 0.100 M

Volume prepared solution = 750.0 mL

Molarity prepared solution = 0.05 M

Step 2: Calculate initial volume

C1*V1 = C2V2

⇒with C1 = the initial concentration = 0.100 M

⇒with V1 = The initial volume = TO BE DETERMINED

⇒with C2 = the new concentration = 0.0500M

⇒with v2 = the new volume = 750.0 mL = 0.750 L

0.100 M * V1 = 0.0500 M * 0.750 L

V1 = (0.0500M * 0.750L)/0.100 M

V1 = 0.375 L = 375 mL

We need 375 milliliters of 0.100 M NaHCO3 solution

Discuss electrochemical principle about rusting of iron​
Levart [38]

Answer:

The electrochemical phenomenon of rusting of iron can be described as : At Anode: Fe (s) undergoes oxidation to releases electrons. Electrons released at anode move to another metal and reduce oxygen in presence of H+. It is available from H2CO3 formed from the dissolution of CO2 from air into water.

What does it mean to say that the average daytime relative humidity of a particular city is 31 percent?
Irina-Kira [14]
This means that the air in that city has less than a third of water vapor it could contain under the same circumstances. Relative humidity is the ratio of water vapor that the air contains to the maximum amount it could carry at the same temperature. When the humidity is high the water vapor in the air is a lot and vice versa.
