Answer:
2x10⁻⁴cm and 7.9x10⁻⁵ inches
Explanation:
Micrometer, μm, is an unit of length. Could be related with another units of lenght as, for example:
1.0μm = 1x10⁻⁴cm
1.0μm = 3.93701x10⁻⁵ inches
That means, 2.0μm are:
2.0μm * (1x10⁻⁴cm / 1μm) = 2x10⁻⁴cm
And:
2.0μm * (3.93701x10⁻⁵ inches / 1μm) = 7.9x10⁻⁵ inches
Answer:
covalent bond
Explanation:
The bond which is most common in the organic molecules is the covalent bond which involves sharing of the electrons between the two atoms.
Glycosidic bond, also known as glycosidic linkage is type of the covalent bond which joins carbohydrate molecule to other group that may not or may be a carbohydrate.
Glycosidic bond is the bond which is formed between hemiacetal or hemiketal group of the saccharide and hydroxyl group of compounds like alcohol.
<span>the ionization constant, Ka, for and indicator, HIn, is 1.0x10^-8. The color of the unionized form is red and the color of the ionized form is yellow. What is the color of the indicator in a solution whose pH is 4.6? (Hint: the color of an indicator can be estimated by considering the ratio of [HIn]/[In]. If the ratio is equal to or greater than 10, the color will bet hat of the unionized form. If the ratio is equal to or smaller than 0.1, the color will be that of the ionized form.

substitute for pH and find the value of A-/HA.

</span><span>so it'd just be 1x10^-8 divided by 4.6</span>
