The percent yield : 81.5%
<h3>Further explanation</h3>
Percent yield is the compare of the amount of product obtained from a reaction with the amount you calculated
General formula:
Percent yield = (Actual yield / theoretical yield )x 100%
An actual yield is the amount of product actually produced by the reaction. A theoretical yield is the amount of product that you calculate from the reaction equation according to the product and reactant coefficients
Reaction
2CO+O₂⇒2CO₂
mol CO(MW=28,01 g/mol)

mass CO₂ (theoretical)(MW=44,01 g/mol)

the percent yield :

Hello!
To calculate the
household concentration of NaOH we need to use the
dilution formula, clearing for M2, as you can see in the equation below:

Now, we input the values from the data we have onto this equation. M1=19,1 M; V1=10 mL; V2=400 mL, and solve the equation to get the result:

So, the
household concentration of NaOH will be 0,48 M
Have a nice day!
Answer:
B
Explanation:
because a periodic table shows the arrangement of element according to their atomic number and their valence neither
isotopes nor colour
Answer:
SiH4
Explanation:
4 hydrogens serve a the base and the Si is on top which forms a tetrahedral shape.
