Question

26 multiple choice 1 point how many neutrons are in $_{16}^{32}s^{2 - }$? 34 14 18 16 27 multiple choice 1 point determine if the following is an intensive property or an extensive property the density of gold is 19.3 g/ml intensive extensive

Explanation:

Step1: Recall atomic - notation relationship

In the atomic notation $_{Z}^{A}X$, $A$ is the mass number and $Z$ is the atomic number. For $_{16}^{32}S^{2 - }$, $A = 32$ and $Z=16$.

Step2: Use the formula for neutron number

The number of neutrons $N$ is given by $N=A - Z$. Substituting $A = 32$ and $Z = 16$ into the formula, we get $N=32 - 16=16$.

Step3: Recall the definition of intensive and extensive properties

Intensive properties do not depend on the amount of substance, while extensive properties do. Density is an intensive property as it has the same value for a given substance regardless of the amount.

Answer:

1. D. 16
2. A. intensive
