Answer:
2
Explanation:
In the equation, Cl is chlorine and there is a number "2" so that the correct answer is 2.
A. ATOMS CAN NOT BE DIVIDED (INDIVISIBLE)
Answer:
V = 122.2 L
Explanation:
Given data:
Number of molecules of water = 6.58×10²⁴
Volume of oxygen produced = ?
Solution:
Chemical equation:
2H₂O → 2H₂ + O₂
<em>Number of moles of water:</em>
Number of moles = 6.58×10²⁴/ 6.022 ×10²³
Number of moles = 1.09 ×10¹ mol
Number of moles = 10.9 mol
Now we will compare the moles of water with oxygen:
H₂O : O₂
2 : 1
10.9 : 1/2×10.9 = 5.45 mol
Volume of oxygen:
PV = nRT
V = nRT/P
V = 5.45 mol × 0.0821 L. atm. K⁻¹. mol⁻¹× 273 k / 1 atm
V = 122.2 L. atm. / 1 atm
V = 122.2 L
The correct answer is D.
You can use a pointing word in paragraph two that refers to a word in paragraph one.
It is in connecting paragraph where we can use signal words or time signals to emphasize more on paragraphs. For example, second, meanwhile.
