Answer:

If it contains only 2 elements it will begin with “hydro” as in

hydrochloric acid (HCl). If it contains more than 2 elements it is named based on the polyatomic (oxy) anion, as in nitric acid (HNO3), nitrous acid (HNO2), sulfuric acid (H2SO4). If the element has more than one possible charge, the value of the charge comes after the element name and before the word ion. Thus, Fe 2+ is the iron two ion, while Fe 3+ is the iron three ion.

How many electrons do atoms like to have in their outer shell?

irakobra [83]

Explanation:

In general, atoms are most stable, least reactive, when their outermost electron shell is full. Most of the elements important in biology need eight electrons in their outermost shell in order to be stable, and this rule of thumb is known as the octet rule.

Carbohydrate metabolic enzymes bind D-glucose specifically. D-glucose has an estimated caloric value of 1 k.cal per 4 grams of c

Aleksandr [31]

Answer:

D) 0 k.cal per 4 grams

Explanation:

Genarally, glucose can be classified into two enantiomers such as d-glucose and l-glucose. The d-glucose is the most common sugar that bodies of living organisms use as source of energy. However, l-glucose is an organic compound and it is one of the aldohexose monosaccharides. It is the l-isomer of glucose and commonly refer to as a low-calorie sweetener. The l-glucose is relatively indistinguishable in taste from d-glucose but cannot be used as a source of energy. Therefore, in the given problem:

if d-glucose has an estimated caloric value of 1 k.cal per 4 grams of carbohydrate, then the caloric value of l-glucose will be 0 k.cal per 4 grams.

A smaple of 1cm cuvette gives an absorbance reading of 0.558. if they absorptivity for this sample is 15000l/(mol.cm), what is t

Mazyrski [523]

To solve this problem, we use Beer's Law: A= ε.l.c
A is the absorbance- 0,558
ε is the molar absorptivity- is 15000 L⋅mol-1cm-1
l is the length of the cuvette- 1 cm
c is the molar concentration

Applying the formula,
0,558= 15000 x 1 x c
0,558/15000= c
c= 3.72×10⁻⁵ mol⋅L⁻¹
