The answer is 1/2 because of how many times does 2 go into 2 which is 1 and how many times 2 can go into 4 which is 2. So 1 would go on top and the 2 would go on the bottom

Rate using numbers:

  1. Select a specific scale rating such as 1 to 5 or 1 10.

How many half-lives will pass by the time 1.56% of I-131 is present? B. Approximately how many days does that equal? *
serg [7]

Answer: Hmmmmm that's crazy....

There are a couple of equations one could use for this type of problem, but I find the following to be the easiest to use and to understand.

Fraction remaining (FR) = 0.5n

n = number of half lives that have elapsed

In this problem, we need to find n and are given the FR, which is 1.56% or 0.0156 (as a fraction).

0.0156 = 0.5n

log 0.0156 = n log 0.5

-1.81 = -0.301 n

n = 6.0 half lives have elapsed

Explanation:

Just wanted to help. Hopefully it's correct wouldn't want to waster your time ;)

Evaluate each scenario to determine whether it represents a chemical reaction.
vova2212 [387]

Explanation:

A chemical reaction is one in which a chemical change occurs.

During a chemical change;

  • The process is irreversible
  • New kinds of matter produced
  • There is a change in mass

Based on these premise;

 Baking  cake batter is a chemical reaction because you cannot reverse the process

  Shredding a paper is not a chemical reaction because no new kind of matter is produced.

  Twisting of a metal wire is not a chemical reaction

   Yellowing of newspaper in sunlight is a chemical change. The process cannot be reversed
