Answer:
14.91 mL
Explanation:
<em>Assuming the weak acid is monoprotic</em>, we can solve this problem using the equation:
Where subscript 1 stands for the Volume and Concentration of the weak acid, while 2 stands for those of NaOH.
We <u>input the data</u>:
- 25.00 mL * 0.1084 M = 0.1817 M * V₂
And solve for V₂:
You want to divide by avagadros number (6.22 x 10^23). This will cancel the atoms unit and give moles, moles of Iridium. Now you want to calculate the atomic mass of Iridium which is in units of grams per mole. Multiply these two numbers and the moles will cancel giving you grams.
Setting up a dimension analysis type of thing helps tremendously. See what you have to cancel in order to get what you want. We canceled the atoms, then we canceled the moles, and then we got grams.
Answer:
The ring of fire
Explanation:
The ring of fire is where they meet or at the fault lines
Lets get this straight:-
Protons → Positive charge, found in nucleus, heavy
Now, the only one we see that seems to be correct is A) positive charge, heavy, found in the nucleus of an atom
