Answer:
The measure of angle ABE is 27°.
Explanation:
Consider the below figure attached with this question.
Given information: ∠ABE=2n+7 and ∠EBF=4n-13.
From the below figure it is clear that ∠ABE and ∠EBF are congruent.
Isolate variable terms on one side.
Divide both sides by 2.
The value of n is 10.
We need to find the measure of ∠ABE.
Therefore, the measure of angle ABE is 27°.
Answer:
1) fractional distillation
3) centrifugation
Answer:
322 mmHg
Explanation:
Step 1: Given data
- Total pressure of the gaseous mixture (P): 756 mmHg
- Partial pressure of helium (pHe): 229 mmHg
- Partial pressure of nitrogen (pN₂): 205 mmHg
Step 2: Calculate the partial pressure of oxygen (pO₂)
The total pressure of the gaseous mixture is equal to the sum of the partial pressures of the individual gases.
P = pHe + pN₂ + pO₂
pO₂ = P - pHe - pN₂
pO₂ = 756 mmHg - 229 mmHg - 205 mmHg
pO₂ = 322 mmHg
Answer:
0.225 atm
Explanation:
v1=450ml÷1000=0.45l(1l=1000ml)
P1=1
v2=2.00l
p2=?
p1v1=p2v2
p2=p1v1/v2
=1×0.45/2
=0.225
so the answer is first one
