Answer:
The protons and electrons in each element are equal. The sulfur has 16 electrons and 16 protons. But the ionic atom's electron quantity changes depending on how many it has gained. 'S2-' has gained 2 electrons, which means it has now 18 electrons and 16 protons. 16 neutrons
Explanation:
Answer:
See figure 1
Explanation:
In this question, we have to remember that each <u>carbon has 4 electrons</u> and each <u>hydrogen has 1 electron</u>. Additionally, the structure proposed have to have <u>8 electrons for each atom</u> <u>(except hydrogen)</u>. With this in mind, we need to have a <u>double bond</u> between the carbons, because in this arrangement each carbon would have 8 electrons <u>(octet rule)</u>.
See figure 1

Answer:
the percent error expected from each of theses person's body:
in homes:
% E = 0.14267 %
in doctor's office:
% E = 0.257 %
Explanation:
- ° C = ( ° F - 32 ) * (5/9)
- % E = ( | true - exp | / true ) * 100
- body temp = 38.9 ° C = 102.02 ° F
thermometer used in homes:
⇒ T = 102.02 ° F +/- 0.1 ° F = 102.12 ° F ∧ 101,92 ° F
⇒ T = 102.12 ° F = 38.9555 ° C
⇒ % E = ( | 38.9 - 38.9555 | ) / 38.9 ) * 100 = 0.14267 %
in the doctor's oficce:
⇒ T = 38.9 ° C +/- 0.1 ° C = 39 ° C ∧ 38.8 ° C
⇒ % E = (( | 39 - 38.9 | ) / 38.9 ) * 100 = 0.257 %
