Four haem groups and 4 globin
Answer:
4000mL
Explanation:
Using the combined gas law equation as follows:
P1V1/T1 = P2V2/T2
Where;
P1 = initial pressure (atm)
P2 = final pressure (atm)
V1 = initial volume (mL)
V2 = final volume (mL)
T1 = initial temperature (K)
T2 = final temperature (K)
According to the information given in this question:
V1 = 1000mL
T1 = 20K
P1 = 1.0atm
V2 = ?
P2 = 0.5atm
T2 = 40K
Using P1V1/T1 = P2V2/T2
1 × 1000/20 = 0.5 × V2/40
1000/20 = 0.5V2/40
50 = 0.5V2/40
50 × 40 = 0.5V2
2000 = 0.5V2
V2 = 2000/0.5
V2 = 4000mL
Answer:
In context|chemistry|lang=en terms the difference between halogen and halide. is that halogen is (chemistry) any element of group 7, ie fluorine, chlorine, bromine, iodine and astatine, which form a salt by direct union with a metal while halide is (chemistry) a salt of any halogen acid.
Explanation:
1,3-cyclopentanediol has 3 possible stereoisomers. Two of which are enantiomers and are therefore, optically active, while one is optically inactive. The enantiomers are the <em>trans-</em> isomers which are (1R,3R)-1,3-Cyclopentanediol, and (1S,3S)-1,3- Cyclopentanediol.
The stereoisomer that is not optically active is the <em>cis- </em>isomer which is (1S,3R)-1,3-Cyclopentanediol and is shown in the illustration below.
