Absolute dating is finding the exact date of an artifact such as a fossil using a technique such as radioactive dating, etc.

Explanation:

Absolute dating is the process of determining an age on a specified chronology in archaeology and geology. Some scientists prefer the terms chronometric or calendar dating, as use of the word "absolute" implies an unwarranted certainty of accuracy.

An aqueous solution contains 0.397 M ammonia. Calculate the pH of the solution after the addition of 4.63 x 10-2 moles of perchl
SSSSS [86.1K]

Answer:

9.308

Explanation:

The computation of the pH of the given solution is shown below:

But before we need to determine the HI molarity which is

Molarity\ of\ HI = \frac{moles}{volume \ in\ L}

= \frac{4.63\times10^{-2}}{0.250}

= 0.1852  M

Now

As we know that

NH_3 + HI = NH_4I

So,

NH_4I = HI = 0.1852 M

Now the molarity of NH_3 left is

= 0.397 - 0.1852

= 0.2118

pOH = pKb + log (\frac{NH_4I}{NH_3})

= 4.75 + log(\frac{0.1852}{0.2118})

= 4.692

Now as we know that

pH = 14 - pOH

= 14 - pOH

= 14 - 4.692

= 9.308

We simply applied the above equations

You see a worm crawling along the ground and wonder if scientists consider it living or nonliving. Which item below would not be
lisov135 [29]

Answer: a. A worm can move so it must be living.

Explanation:

If a worm is moving it is classified as a moving worm also known to be living if moving.

A worm could reproduce therefore it is living.

Worms do pass dirt into and through there bodies to eat of the minerals and discarding things through and let out.

If you do cut a worm in half it may damage it but since it has basically two heads on girl one boy and cut in half it may split them up, and make damage but they will eventually grow back if the injuries are not severe.

HAPPY NEW YEAR!
