What is reflux? isn't it like when u aren't able to digest something?
Answer: 1 proton, 0 electron and 1 neutron are present in 1 H⁺ isotope.
Answer:
Percent yield = 57%
Explanation:
Given data:
Number of moles of propane = 4.50 mol
Number of moles of carbon dioxide = 7.64 mol
Percent yield = ?
Solution:
Chemical equation:
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O
Now we will compare the moles of propane and carbon dioxide.
C₃H₈ : CO₂
1 ; 3
4.50 : 3×4.50 = 13.5 mol
Percent yield:
Percent yield = actual yield / theoretical yield × 100
Percent yield = 7.64 mol / 13.5 mol × 100
Percent yield = 0.57× 100
Percent yield = 57%
Answer:
C. how the size of a magnet affects the strength of its magnetic pull on objects.
Explanation:
"Magnetic force" is <em>inversely proportional to distance squared. </em>This is also related to the size of a magnet. The bigger the size, the bigger the domain it occupies and the stronger the magnetic field. However, this is not often the case and it largely depends on the types of magnets.
In the situation above, Jazelle wanted to determine how her five different-sized magnet affect the strength of their magnetic pull on the paper clips. In order to do this, she tried to<em> measure the distance</em>. The<em> closer the distance</em>, the <em>higher the magnetic field</em> and the stronger the strength. The farther the distance, the<em> lower the magnetic field</em> and the <em>weaker the strength.</em>
So, this explains the answer.
One mole contains 6.022×10^23 actually
