Option 4. ratio of electrons to protons
Isotope that has atomic number of 82 is stable. An element that has an atomic number ∠82 more stable except Tc and Pm. Also there is the concept that isotopes consisting a combination of even-even,even-odd,odd-even, and odd-odd are all stable. Many isotopes with no magic numbers of nucleons are stable
Answer:
Option 2, Half of the active sites are occupied by substrate
Explanation:
Michaelis-Menten expression for enzyme catalysed equation is as follows:
Here, is Michaelis-Menten constant and [S] is substrate concentration.
When [S]=Km
Rearrange the above equation as follows:
when [S]=Km, the rate of enzyme catalysed reaction becomes half of the maximum rate, that means half of the active sites are occupied by substrate.
Therefore, the correct option is option 2.
Answer:
Explanation:
We have to start with the reaction:
<u>We have 2 carbons, 6 hydrogens and 38 oxygens on both sides</u>.
Now the <u>molar ratio</u> between and is 2:12 or . With this in mind we can calculate the moles of , so:
I hope it helps!
The best equation which illustrate the law of conservation of mass is
Zn +2 HCl --> ZnCl2 + H2
This is because the mass of the product is equal to the mass of reactant. for example the mass of Zn is 1 in the reactant and product side. According to the law of mass conversation the mass in a isolated system is neither created nor destroyed by chemical reaction or physical transformation
