<h2>
Hello!</h2>
The answer is:
The percent yield of the reaction is 32.45%
<h2>
Why?</h2>
To calculate the percent yield, we have to consider the theoretical yield and the actual yield. The theoretical yield as its name says is the yield expected, however, many times the difference between the theoretical yield and the actual yield is notorious.
We are given that:
Now, to calculate the percent yield, we need to divide the actual yield by the theoretical and multiply it by 100.
So, calculating we have:
Hence, we have that the percent yield of the reaction is 32.45%.
Have a nice day!
Answer:Well, if you mean atoms, it has 2 Hydrogen atoms and 1 Oxygen.
Explanation:Water is H20 therefore, it has 2 Hydrogen atoms and 1 Oxygen. Water isn't made up of particles, they are made of atoms.
answer:
ionic bonds form between oppositely charged ions
explanation:
- an ionic bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions.
- ionic bonds are formed between a cation, which is usually a metal, and an anion, which is usually a nonmetal.
- a covalent bond involves a pair of electrons being shared between atoms.
Explanation:
Following factors can affect blood pressure :
- Smoking.
- Lack of physical activity.
- Too much salt in the diet.
Answer:
Moles of BCl₃ needed = 0.089 mol
Explanation:
Given data:
Moles of BCl₃ needed = ?
Mass of HCl produced = 10.0 g
Solution:
Chemical equation:
BCl₃ + 3H₂O → 3HCl + B(OH)₃
Number of moles of HCl:
Number of moles = mass/molar mass
Number of moles = 10.0 g/ 36.46 g/mol
Number of moles = 0.27 mol
Now we will compare the moles of HCl with BCl₃.
HCl : BCl₃
3 : 1
0.27 : 1/3×0.27 = 0.089 mol
