- STP (Standard Conditions for Temperature and Pressure) = 22.4 L per mole at 1 atm, 273 K
<h3>
Explanation:</h3>
<u>Step 1: Define</u>
0.07 mol Ne (g)
<u>Step 2: Identify Conversions</u>
STP - 22.4 L per mole
<u>Step 3: Convert</u>
- Set up:
![\displaystyle 0.07 \ mol \ Ne(\frac{22.4 \ L \ Ne}{1 \ mol \ Ne})](https://tex.z-dn.net/?f=%5Cdisplaystyle%200.07%20%5C%20mol%20%5C%20Ne%28%5Cfrac%7B22.4%20%5C%20L%20%5C%20Ne%7D%7B1%20%5C%20mol%20%5C%20Ne%7D%29)
- Multiply:
![\displaystyle 1.568 \ L \ Ne](https://tex.z-dn.net/?f=%5Cdisplaystyle%201.568%20%5C%20L%20%5C%20Ne)
<u>Step 4: Check</u>
<em>Follow sig fig rules and round. We are given 1 sig fig.</em>
1.568 L Ne ≈ 2 L Ne
It's harmful to humans; especially Children and Infants. Because it affects the development of the brain and nervous system
Answer:
+1
Explanation:
For the equation to be balanced, the total mass number and the total atomic number on both side of the equation but be equal.
This is illustrated:
For the mass number:
Left side: 22
Right side: 22 + 0 = 22
For the atomic number:
Left side: 11
Right side: 10 + x
11 = 10 + x
Collect like terms
x = 11 - 10
x = 1

In a redox reaction electrons are lost and gained in equal numbers. The species that is oxidized gives electrons to the species that is reduced. I hope this helps. Let me know if anything is unclear.
