Use n1/V1 = n2/V2
.1/2 = .4/V2
.1V2 = .8
V2 = 8 L or D
Answer:
A) forms a helix and no branch points
Explanation:
amylopectin: consisting of many glucose rings linked together to form lomg molecule with numerous ramifications
Elements are the same type of atoms, so there is nothing else to separate. Hydrogen has hydrogen atoms, and no other kind. Therefore nothing can be taken out of it anymore. Chemical x is a mixture, made by y and z. Nothing can make up y and z but themselves.
PH is simply a convenient way to denote hydronium ion concentration (usually in moles per liter or molarity). pH is calculated from the given concentration using the equation: pH = -log [H3O⁺]
To find [H3O+] from the given equation, we apply the antilog.
[H3O⁺] = 10⁻⁽pH⁾ or ten raised to the negative value of pH
A solution with a pH of 3.43 has a hydrogen ion concentration of 3.7154x10^-4 moles per liter.
There are four types of chemical bonds essential for life to exist: Ionic Bonds, Covalent Bonds, Hydrogen Bonds, and van der Waals interactions. We need all of these different kinds of bonds to play various roles in biochemical interactions. These bonds vary in their strengths.
To play a variety of roles in biochemical interactions, we require all of these diverse sorts of linkages. The tensile strength of these linkages varies. In chemistry, we consider the range of strengths between ionic and covalent bonds to be overlapping. This indicates that in water, ionic bonds usually dissociate. As a result, we shall consider these bonds from strongest to weakest in the following order:
Covalent is followed by ionic, hydrogen, and van der Waals.
