D should be the correct answer. isotopes are atoms that have the same atomic number (number of protons) but different atomic masses (number of protons and neutrons). isotopes also have the same number of electrons since atoms need to have equal numbers of protons and electrons to not be considered ions. Since the number of protons determines the chemical properties of the atom, we can say that all isotopes have the same chemical properties due to the fact that all isotopes have the same atomic number.
I hope this helps. Let me know in the comments if anything is unclear.
<h2>Answer:</h2>
pOH = 4.6
<h2>Explanations:</h2>
The sum of pH and pOH of a solution is 14as shown:

Given the following parameter
pH = 9.4
Substitute the given parameters into the formula to have:

Hence the pOH of the solution of pH of 9.4 is 4.6
I’m pretty sure it will be the answer choice B
Answer:

Explanation:
salivary gland: 1
stomach: 2
small intestine: 6
liver: 4
gallbladder: 5
large intestine: 3
The answers correspond with the numbers on the text boxes, so you would drag number 1 to the salivary gland and so on.
