Answer:
B
Explanation:
It's B because the first trial of an experiment may not always be right so you want to run multiple trials
In order to answer this question we must look at the image which I have attached.
The red atoms refer to oxygen atoms, the grey atoms are carbon atoms and the blue atoms are nitrogen. Therefore, the equation from the image suggests:
2CO + 2NO → 2CO₂ + N₂
Looking closely at the options given, several of them could be eliminated immediately since they are not balanced equations like B, C and E. Therefore, only A or D could be the answers.
The answer is option

D.) 2CO + 2NO → 2CO2 + N2</span>
If you are talking about bonds they are influenced by electronegativity and how many valence electrons they have.

Answer:</h3>
The root mean square speeds of O₂ and UF₆ is 513m/s and 155 m/s respectively.
<h3>
Solution and Explanation:</h3>
- To find how fast molecules or particles of gases move at a particular temperature, the root mean square speed is calculated.
- Root mean square speed of a gas is calculated by using the formula;

Where R is the molar gas constant, T is the temperature and M is the molar mass of gas in Kg.
<h3>Step 1: Root mean square speed from O₂</h3>
Molar mass of Oxygen is 32.0 g/mol or 0.032 kg/mol
Temperature = 65 degrees Celsius or 338 K
Molar gas constant = 8.3145 J/k.mol


<h3>
Step 2: Root mean square speed of UF₆ </h3>
The molar mass of UF₆ is 352 g/mol or 0.352 kg/mol


Therefore; the root mean square speeds of O₂ and UF₆ is 513m/s and 155 m/s respectively.
