<span>The combined Boyle's and Charles' gas law says P1V1/T1 = P2V2/T2 </span>
<span>In this case we have (2.5 atm) (900 ml) / 298 K = (P2) (450 ml) / 336 K -----> </span>
<span>7.55 = 1.34P2 -----> P2 = 7.55 / 1.34 = 5.63 atm</span>
Answer:
The resistance would be 64.10 ohms.
have a nice day my dude
Answer:
3-ethyl-4-methyl Heptane
Explanation:
longest chain is straight .
we start assigning number from where we are close to the branch to this mean its from left hand side. and we saw two chain 1 is ethyl and other is methyl . In alphabetical order e comes first as compare to m so we write ethyl first after that methyl and than in last we write longest chain name with ane (bcz we only have single vonds).
