Answer:
The rate constant for a first order reaction is 60 s 1. How much time will It take to reduce the initial concentration of the reactant to its 1/6 th value? Answer: Question 9. For a first order reaction, show that time required for 99% completion is twice the time required for the completion of 90% of reaction…
Explanation:
The rate constant for a first-order reaction is equal to the negative of the slope of the plot of ln[H 2 O 2] ... (from 6.00 hours to 12.00 hours), it decreases from 0.500 M to 0.250 M; ... The half-life of a reaction is the time required to decrease the amount of a given reactant by one-half. The half-life of a zero-order reaction decreases as ...
Answer:
1. Prints “o”
This is because charAt returns with the character(a,b,c,etc) at the index. In this case it’s 4. It’s important to remember that the charAt searches for the character at the index and not literal place. The string starts at 0 instead of 1. So h = 0, e = 1, l = 2, l = 3, o = 4.
2. Prints “5”
The str.length() method prints out the literal count of characters in a string. Starting from 1 instead of 0. “hello” has 5 characters(the word letters can’t be used as the method also counts spaces and other symbols).
3. Prints “he”
The substring method prints out the characters from the first index parameter, in this case “h” since it’s in the 0 index, to the last character before the last index parameter. This would be “e”. If it were a longer length then those letters in between would be printed as well.
Answer:
Explanation:
b2=8n
1. Multiply 12*8
12*8=96
2. Write out
b2=96
Ps...
I think you forgot the other part of the question so here
b=48
Have a nice day!
The answer would be D cause it has the word boring in it and the initiative has to have words like fun,eat,run,believe,or to follow
