Answer: 82.9kPa
Explanation:
Gas pressure can be measured in several units, they include psi (pound per square inch), kPa (kilo pascal).
Recall that:
1 Kilopascal (kPa) = 0.14503773779 psi
So, let Z kPa = 12.02 psi
To get the value of Z, cross multiply
12.02 psi x 1kPa = 0.14503773779 psi x Z kPa
12.02 = 0.14503773779Z
Divide both sides by 0.14503773779
12.02/0.14503773779 = 0.14503773779Z/0.14503773779
82.9 kPa = Z
Thus, the 12.02 psi is equivalent to 82.9 kPa
<h2>Natural Abundance for 10B is 19.60%</h2>
Explanation:
- The natural isotopic abundance of 10B is 19.60%.
- The natural isotopic abundance of 11B is 80.40%.
- The isotopic masses of boron are 10.0129 u and 11.009 u respectively.
For calculation of abundance of both the isotopes -
Supposing it was 50/50, the average mass would be 10.5, so to increase the mass we need a more percentage of 11.
Determining it as an equation -
10x + 11y= 10.8
x+y=1 (ratio)
10x + 10y = 10
By taking the denominator away from the numerator
we get;
y = 0.8
x + y = 1
∴ x = 0.2
To get percentages we need to multiply it by 100
So, the calculated abundance is 80% for 11 B and 20% 10 B.
Answer:
G : pent-2-ene
H : H2o
I : pent-1-ene
Explanation:
The OH would combine with H from H-O4SH
Then the O attached to the carbon would get detached taking the electrons with it, leaving carbon an positively charged.
The OH now combined with H-O4SH would take the H away from the acid forming H2O and (O4SH)-
The negative ion of (O4SH)- would then take the H from positively charged C forming the sulphuric acid back. It does not take the electrons with it*
Which is why the carbon can then form a double bond with the excess electron (2). the major product would be pent-2-ene and minor would be pent-1-ene.
This is because pent-2-ene is more stable than pent-1-ene. (Due to secondary carbon and primary carbon factor)
This is the whole backstage story though.
