T The word that means the gradual change and build up of organisms in an environment is evolution
The molecular formula of the compound is .
<h3>Given:</h3>
Mass of Cr = 0.70 g
Mass of S = 0.65 g
Mass of O = 1.30 g
Molecular mass = 392.2 g
Moles of Cr =
= 0.01346 mol
Moles of S =
= 0.02025 mol
Moles of O =
= 0.08125 mol
Dividing both sides with lower quantity ;
≅
And
392.2 = n (52.0 + 6 × 16.0)
n = 2
Therefore, the molecular formula of the compound is .

Answer:
T₂ = 550.60 K
Explanation:
Given data:
Initial temperature = 16.3°C (16.3+273 = 289.3 K)
Initial pressure = 9.30 atm
Final temperature = ?
Final pressure = 17.7 atm
Solution:
According to Gay-Lussac Law,
The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.
Mathematical relationship:
P₁/T₁ = P₂/T₂
Now we will put the values in formula:
9.30 atm / 289.3 K = 17.7 atm/T₂
T₂ = 17.7 atm × 289.3 K / 9.30 atm
T₂ = 5120.61 atm. K /9.30 atm
T₂ = 550.60 K
