Answer:
hi 5th grader, stop trying to cheat :)
Explanation:
The formula of butane is C4H10 but I don't how many atoms it contains though
Answer:
P₂ = 0.8 atm
Explanation:
Given data:
Initial pressure = 1 atm
Initial volume = 7 L
Final volume = 9 L
Final pressure = ?
Solution:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = Initial volume
P₂ = Final pressure
V₂ = Final volume
Now we will put the vales in formula.
P₁V₁ = P₂V₂
P₂ = P₁V₁ /V₂
P₂ = 1 atm × 7 L / 9 L
P₂ = 7 atm. L / 9 L
P₂ = 0.8 atm
Correct Answer: Mixture will be heterogeneous
Reason:
The mixture is said to be homogenous, if it contains single phase, On other hand, heterogenous system has, multiple phases. When, oil and vinegar are mixed together, on standing, the two liquids separates out as different phases. Hence, the mixture will be refereed as heterogeneous.
the answer is D. just took the test
