So that they combine smoothly and you aren't left with separated looking salad dressing. With polarity only, like-polarities dissolve like-polarities. So you must make sure that all your ingredients are polar or all are nonpolar.
Answer:
Bread is a Molecule.
Explanation:
This is what I found.
Bread cannot be classified as a compound. Compounds are formed when two or more substances are bonded together chemically, however, mixtures are not chemically bonded.
The chemical building blocks of bread are proteins and starch. Starch molecules are long, chained polymers of simple sugars (such as glucose) joined end to end by chemical bonds. Proteins on the other hand are more complex, made up of varying combinations of different amino acids.
Hope this helps.
Hey there!:
From the given data ;
Reaction volume = 1 mL , enzyme content = 10 ug ( 5 ug in 2 mg/mL )
Enzyme mol Wt = 45,000 , therefore [E]t is 10 ug/mL , this need to be express as "M" So:
[E]t in molar = g/L * mol/g
[E]t = 0.01 g/L * 1 / 45,000
[E]t = 2.22*10⁻⁷
Vmax = 0.758 umole/min/ per mL
= 758 mmole/L/min
=758000 mole/L/min => 758000 M
Therefore :
Kcat = Vmax/ [E]t
Kcat = 758000 / 2.2*10⁻⁷ M
Kcat = 3.41441 *10¹² / min
Kcat = 3.41441*10¹² / 60 per sec
Kcat = 5.7*10¹⁰ s⁻¹
Hence kcat of xyzase is 5.7*10¹⁰ s⁻¹
Hope that helps!
<h3><u>Answer;</u></h3>
= 0.6224 M
<h3><u>Explanation</u>;</h3>
Molarity is given by the formula;
Molarity = Number of moles/Volume
But moles = mass/Molar mass
Thus;
Moles = 12.47 g/80.043 g/mol
= 0.1556 Moles
Therefore;
Molarity = 0.1556 moles/0.25
<h3> <u>= 0.6224 M</u></h3>
Answer is: solid is the state in which matter has a definite shape and volume.There are two types of solids:crystalline (solids that have a very orderly, 3-dimentional arrangement of atoms or molecules) and amaorphous (composed of atoms or molecules that are in no particular order).
Plasma is is the state of matter that does not have a definite shape or volume. <span>Plasmas and some solids (metals) conduct electric current.</span>
