Answer:
0.5 atm is equal to 380mmHg.
Explanation:
For every 1 atm, it is equal to 760mmHg.
Therefore, 0.5 atm is 760/2, which is 380mmHg.
Explanation:
It is known that relation between wavelength and frequency is as follows.

where,
= wavelength
c = speed of light = 
[/tex]\nu[/tex] = frequency
It is given that frequency is
. Hence, putting this value into the above formula and calculate the wavelength as follows.


= 
or, = 
Thus, we can conclude that wavelength of given radiation is
.
Answer:
C) Q < K, reaction will make more products
Explanation:
- 1/8 S8(s) + 3 F2(g) ↔ SF6(g)
∴ Kc = 0.425 = [ SF6 ] / [ F2 ]³
∴ Q = [ SF6 ] / [ F2 ]³
∴ [ SF6 ] = 2 mol/L
∴ [ F2 ] = 2 mol/L
⇒ Q = ( 2 ) / ( 2³)
⇒ Q = 0.25
⇒ Q < K, reaction will make more products
Answer:
Option-B (2-methylpropene)
Explanation:
The reaction scheme is attached below,
In first step the alkene acts a nucleophile and adds H⁺ across double bond yielding a stable tertiary carbocation.
In the second step the oxygen atom of methanol acts as nucleophile and attacks the positive charge carrying carbon atom resulting in the formation of t-butyl methyl ether.
