how does the structure of atoms (i.e. protons, neutron, and electrons) affect the electric charge of an object or substance.

pickupchik [31]

Electrons contribute greatly to the atom's charge, as each electron has a negative charge equal to the positive charge of a proton. Scientists define these charges as “+1” and “-1. ” In an uncharged, neutral atom, the number of electrons orbiting the nucleus is equal to the number of protons inside the nucleus.:

When reacting Na with Cl2 , we calculated that the theoretical yield should be 12.5 grams. Our actual yield was 13.0 grams. What

vaieri [72.5K]

Answer:

$\boxed {\boxed {\sf 104 \%}}$

Explanation:

Percent ratio is the ratio of the actual yield to the theoretical yield. The formula is below.

$Percent \ Yield} = \frac{{Actual \ Yield}}{{Theoretical \ Yield}} \times 100 \%$

The reaction of sodium and chlorine should theoretically yield 12.5 grams, but the actual yield was 13.0 grams.

actual yield= 13.0 g
theoretical yield = 12.5 g

Substitute these values into the formula.

$Percent \ Yield} = \frac{{13.0 \ g }}{{12.5 \ g}} \times 100 \%$

Divide.

$Percent \ Yield} = 1.04 \times 100 \%$

Multiply.

$Percent \ Yield= 104 \%$

For this reaction, the percent yield is 104%
