Answer:
<h2>6.48 </h2>
Explanation:
The pH of a solution can be found by using the formula
![pH = - log ([ {H}^{+} ])](https://tex.z-dn.net/?f=pH%20%3D%20-%20log%20%28%5B%20%7BH%7D%5E%7B%2B%7D%20%5D%29)
From the question we have
We have the final answer as
<h3>6.48 </h3>
Hope this helps you
The answer is (4). You may recall the term "radiometric dating," which refers to the dating of old artifacts by measuring proportions of certain radioactive isotopes they contain and making calculations based on their estimated half-lives. Geological formations are dated in this way.
<span>Carbon can also bond with other
four atoms because of its outer shell (valence shell) that has four electrons.
This is the reason why organic molecules can be so large because of this
bonding. Suppose you have a compound of CCl4. You know that chlorine can only
share 1 electron because 7 of its electrons are filled. Also, in carbon, it can
only share 4 electrons because 4 of it are already filled. That is why carbon
needs four chlorine to form CCl4. The answer is letter <u>B.</u></span>
Chemical and physical properties are ways that scientists classify a substance. The color or mass it has are physical properties. However, chemical properties are chemical changes a substance undergoes.
