0.4% = 0.004
(1.5mg /1000g ) / 0.004 = 0.375ml
The pressure of the gas is 3.52 atm
<u><em>calculation</em></u>
This is calculated using the Boyle's law formula
that is P1V1= P2V2 where;
P1 = 1.65 atm
V1 =22.8 L
P2 =? atm
V2 = 10.7 L
make P2 the subject of the formula by dividing both side by V2
P2 = P1V1 / V2
P2 = (1.65 atm x 22.8 l) / 10.7 L = 3.52 atm
convection is the transfer of heat through the air
Answer: C you have a small amount of substance
<span>I would say D because the Br is bonded to a tertiary carbon (a carbon bonded to three other carbon atoms). This makes the bond more stable compared to if the Br was bonded to a primary or secondary carbon, and so it is unlikely for spontaneous substitution of Br for OH to occur. Hydrolysis occurs through reaction intermediates that make the making and breaking of C-OH and C-Br bonds respectively more favourable.</span>
