Hey!
According to scientists across the globe, Pluto is not a "planet", but a "dwarf planet." This also is determined when you were born and taught different ideals, cause everyone changed their sort of learning on planets overtime in our generation. Hope this helped!
Answer: Remove the watch and watchband immediately, and rinse his wrist for at least 15 minutes to be sure all hazardous material has been washed away. Let the TA inspect his wrist to see if it is okay.
Explanation:
The question is incomplete, the choices are:
a. Take him to the safety shower, and make sure he stands under it for at least 15 minutes to be sure all hazardous material has been washed away. b. Remove the watch and watchband immediately, and rinse his wrist for at least 15 minutes to be sure all hazardous material has been washed away. c. Let the TA inspect his wrist to see if it is okay.
d. Rinse the watch band before allowing him to put it back on.
An acid is traditionally considered to be any chemical compound that, when dissolved in water, produces a solution with greater hydronium cation activity than pure water, i.e., a pH less than 7. Both corrosive acids (and also corrosive bases) <u>are capable of destroying skin</u> by catalyzing the hydrolysis of fats, which are chemically esters. Also, when acids attack metals, hydrogen gas is often released.
This is why your lab partner should remove the watch and watchband immediately, and rinse his wrist for at least 15 minutes to be sure all hazardous material has been washed away. This ensures that the acid is can not damage the skin. And also the person should make sure that someone qualified checks it to see if it is okay.
Hydrocarbons that lack π bond are called saturated hydrocarbons or alkanes
<h3>Hydrocarbons</h3>
- Hydrocarbon is an organic compound consisting of hydrogen and carbon.
- Hydrocarbons is an examples of 14 group hydrides.
- Hydrocarbons are colorless and hydrophobic.
- Their odors are usually like gasoline or lighter fluid.
- In oil and gas industry, the hydrocarbon in term, combines petroleum and natural gas they are the two naturally occurring phases of hydrocarbon.
<h3>Alkanes</h3>
- Alkanes also konwn as parafins
- They are called as saturated hydrocarbons
- Alkanes contain hydrogen and carbons arranged in tree structure
- Alkanes have two main sources petroleum and natural gas.
Therefore, Hydrocarbons that lack π bond are called saturated hydrocarbons

Here, Molar mass of N2O4 = 92.02 g/mol
So, Number of molecules in 1 mole (92.02 g) = 6.023 * 10²³
Number of molecules in 76.3 g = 6.023 * 10²³ / 92.02 * 76.3
= 6.023 * 10²³ / 1.20
= 5 * 10²³
In short, Your Answer would be approx. 5 * 10²³ molecules
Hope this helps!
