Explanation:
A chemical reaction is one in which a chemical change occurs.
During a chemical change;
- The process is irreversible
- New kinds of matter produced
- There is a change in mass
Based on these premise;
Baking cake batter is a chemical reaction because you cannot reverse the process
Shredding a paper is not a chemical reaction because no new kind of matter is produced.
Twisting of a metal wire is not a chemical reaction
Yellowing of newspaper in sunlight is a chemical change. The process cannot be reversed
Answer:
The element is Dysprosium.
The wt% of KOH = 45%
This implies that there is 45 g of KOH in 100 g of the solution
Density of the solution is given as 1.45 g/ml
Therefore, the volume corresponding to 100 g of the solution is
= 100 g * 1 ml /1.45 g = 68.97 ml = 0.069 L
Now concentration of the concentrated KOH solution is:
Molarity = moles of KOH/vol of solution
= (45 g/56.105 g.mol-1)/0.069 L = 11.6 M
Thus,
Initial KOH concentration M1 = 11.6 M
Initial volume = V1
Final concentration M2 = 1.20 M
Final volume V2 = 250 ml
M1*V1= M2*V2
V1 = M2*V2/M1 = 1.20*250/11.6 = 25.9 ml = 26 ml
We have that the value of Ki for the <em>inhibited </em>reaction
- The place the enzyme inhibitor binds solely to the complicated fashioned between the enzyme and the substrate.
- KI = 3.551mM
<h3>Chemical Reaction</h3>
a)
Generally, if the fee of Vmax binds, the place the enzyme inhibitor binds solely to the complicated fashioned <em>between </em>the enzyme and the substrate.
b) V diminished through 70%
Thereofore
Alternate = 1 - 0.7 = 0.3V
Hence
0.3 =1/ ( 1 + [I]/KI)
1= 0.3(1 + 0.657/KI )
0.3 + 0.1971KI = 1
KI = 3.551mM

Answer:
Intensive
Explanation:
Intensive because it only depends on the type of matter and not the amount. Overall, I say intensive because it will not change when you change the amount of matter.
