Wooahhhh pollution can affect the environment and urself pollited water can affect marine animals and can result them in extinction global warmning melts Antarctica and can cause floodigs and extinction there. This probably wont help but i just free styled lol
Goodluck
Medical books would be the best because it is a valid resource
Answer:
0.535 g
Explanation:
The reaction that takes place is:
- NaCl + AgNO₃ → AgCl + NaNO₃
First we <u>calculate how many AgNO₃ moles are there in 25.0 mL of a 0.366 M solution</u>, using the <em>definition of molarity</em>:
- Molarity = moles / liters
- moles = Molarity * liters
<em>Converting 25.0 mL to L </em>⇒ 25.0 / 1000 = 0.025 L
- moles = 0.366 M * 0.025 L = 0.00915 mol AgNO₃
Then we <u>convert AgNO₃ moles into NaCl moles</u>:
- 0.00915 mol AgNO₃ *
= 0.00915 mol NaCl
Finally we<u> convert NaCl moles into grams</u>, using its <em>molar mass</em>:
- 0.00915 mol NaCl * 58.44 g/mol = 0.535 g
Based on the Hund's Rule, the three electrons in a 2p orbital are arranged as shown in option C.
<h3>What is an orbital?</h3>
The term orbital refers to a region in space where there is a high probability of finding the electron. We know that an electron in an atom could be defined by the use of four sets of quantum numbers which are;
- The principal quantum number
- The orbital quantum number
- The spin quantum number
- The magnetic quantum number
Hund's rule states that, electrons occur singly before pairing takes place. In this case, we can see that the only arrangement that obeys the Hund's Rule is option C.
