Answer:
Explanation:
Some theoretical knowledge is required here. We should understand that whenever we plot the natural logarithm, ln, of a concentration vs. time and obtain a straight line, this indicates a first-order reaction. That said, since this is the case here, we have a first-order reaction with respect to .
The linear equation has the following terms:
It is a linear form of the integrated first-order law equation:
Therefore, the rate constant, k, is:
The natural logarithm of initial molarity is:
Using the equation, we may substitute for t = 600 s and obtain the natural logarithm of the concentration at that time:
Take the antilog of both sides to find the actual molarity:
Answer : The property in the wrong column is, base form hydrogen gas with metals
Explanation :
Acid : It is a substance that has ability of donating a proton or hydrogen ion, .
The properties of an acid are :
- Acids are sour in taste.
- It conduct electricity.
- The texture of an acid solution is sticky.
- It react with carbonates to give salt.
- It changes the color of the litmus paper to red.
- It react with a metal to give compound and hydrogen gas.
Base : It is a substance that has ability of donating hydroxide ion, .
The properties of an base are :
- Base are bitter in taste.
- It conduct electricity.
- The texture of an base solution is slippery.
- It changes the color of the litmus paper to blue.
- It does not react with a metal.
Hence, from the above information, we conclude that the property in the wrong column is, base form hydrogen gas with metals .
