The correct answer is 80 atoms of sulfur.
In order to answer this question we must firstly find the molecular formula of tetrasulfur tetranitrogen. The said molecule has the molecular formula of S4N4.
Therefore, each molecule of S4N4 contains four atoms of sulfur (S).
If one molecule of S4N4 contains 4 sulfur atoms, then twenty molecules contain
20 x 4= 80 atoms of sulfur.

Answer:
2100 kPa
Explanation:
The temperature is constant, so the only variables are pressure and volume.
We can use Boyle’s Law.
p₁V₁ = p₂V₂ Divide both sides of the equation by V₂
p₂ = p₁ × V₁/V₂
p₁ = 485 kPa; V₁ = 648 mL
p₂ = ?; V₂ = 0.15 L = 150 mL Calculate p₂
p₂ = 485 × 648/150
p₂ = 2100 kPa
answer:
D.
explanation:
as days years months go by more and more new elements that are chemically made or are natural are added even though the ones at school have been updated for such a long period of time
