Answer:
If there is a change in the natural shape of the intestines, this can be known as a twisted bowel. A twist in the small intestine is referred to as a volvulus. Twists in the large intestine are known as a colonic volvulus. These abnormal twists or loops can cause an obstruction or other medical conditions which could be fatal. If signs of twisting bowel present, it is important to seek medical attention as quickly as possible.
Answer:
strongest oxidizing agent: 
weakest oxidizing agent: 
strongest reducing agent: Y
weakest reducing agent: X
will oxidize Z
Explanation:
The higher the reduction potential of a species, higher will be the tendency to consume electrons from another species. Hence higher will be the oxidizing power of it's oxidized form and lower will be the reducing power of it's reduced form.
Alternatively, higher reduction potential value suggests that the oxidized form of the species acts as a stronger oxidizing agent and the reduced form of the species acts as a weaker reducing agent.
Order of reduction potential:

So, strongest oxidizing agent: 
weakest oxidizing agent: 
strongest reducing agent: Y
weakest reducing agent: X
As reduction potential of the half cell
is higher than the reduction potential of the half cell
therefore
will oxidize Z into
and itself gets converted into X.
Answer:
3286 grams
Explanation:
For every mol of Ni(CO)4 reactant, a mol of Ni is produced (55.99 mol). Multiply this by the molecular mass of Ni (58.69 g/mol) to give 3286 grams
Answer:
Explanation:
In Polystrene, the molecular formula for the repeat unit =
;
and the atomic weights of Carbon C = 12.01 g/mol
For Hydrogen, it is 1.01 g/mol
Hence, the repeat unit molecular weight is:
m = 8 (12.01 g/mol)+8(1.01 g/mol)
m = 96.08 g/mol + 8.08 g/mol
m = 104.16 g/mol
The degree of polymerization = no-average molecular weight/repeat unit molecular weight.
