Answer:
8.99×10^-7m
Explanation:
The wavelength can be calculated using the expression below
E=hcλ
Where E= energy= 2.21 x 10^-19 J.
C= speed of light= 3x10^8 m/s
h= planks constant= 6.626 × 10^-34 m2 kg / s
E=hcλ
λ= E/(hc)
Substitute for the values
λ=( 2.21 x 10^-19 )/(6.626 × 10^-34 × 3x10^8 )
= 8.99×10^-7m
Reactants are formed from a chemical bond with can be broken down by vaporizing
Answer:
6 moles of NaCl are needed to make 3.0 liters of a 2.0 M NaCl solution.
Explanation:
A 2M solution means that there are 2 moles of solute (NaCl in this case) in 1 liter of solution:
1 L solution-----2 moles of NaCl
3 L solution----x= (3 L solutionx2 moles of NaCl)/1 L solution= <em>6 moles of NaCl</em>
<h2>Competitive inhibitors.</h2>
Explanation:
▪ Transition state analogs can be used as inhibitors in enzyme-catalyzed reactions which are done by blocking the active site of the enzyme.
▪ A transition state analog is somewhat the same as that of the transition state.
▪These are better inhibitors than the substrate analogs in competitive inhibition, the reason is that they bind tighter to the enzyme rather than the substrate.
▪ Thus, they are classified as competitive inhibitors.
