Answer:
I would say, what helps me is really paying attention in class and asking questions, also making sure you study for upcoming test's and quizzes and completely assingments on time
Explanation:
Answer:
1.7 bar
Explanation:
We can use the <em>Ideal Gas Law</em> to calculate the individual gas pressure.
pV = nRT Divide both sides by V
p = (nRT)/V
Data: n = 1.7 × 10⁶ mol
R = 0.083 14 bar·L·K⁻¹mol⁻¹
T = 22 °C
V = 2.5 × 10⁷ L
Calculations:
(a) <em>Change the temperature to kelvins
</em>
T = (22 + 273.15) K
= 295.15 K
(b) Calculate the pressure
p = (1.7 × 10⁶ × 0.083 14 × 295.15)/(2.5× 10⁷)
= 1.7 bar
Answer:
both have the same number of atoms
Explanation:
saw it on a quizlet
Answer:
the relative height of M⁺ : M+1 is; 0.7418 : 0.2228
The relative heights are; In order of increasing mass 100 : 30
Explanation:
Given the data in the question;
The M⁺ peak comes from all ¹²₆C atoms
so, the probability in cholesterol, C₂₇H₄₈O is ( 98.9% )²⁷ = ( 0.989 )²⁷ = 0.7418
The M+1 peak comes from the isotopic carbon ¹³₆C.
so, the probability in cholesterol is ⇒ 1.10% × ( 98.9% )²⁶ = 0.011 × ( 0.989)²⁶
The probability for 27 carbons is ⇒ 27 × 0.011 × ( 0.989)²⁶ = 0.2228
Therefore, the relative height of M⁺ : M+1 is; 0.7418 : 0.2228
The relative heights are; In order of increasing mass 100 : 30
2H2 + O2 -> 2H2O.
