Answer: Lactose
Explanation:
Lactose is a sugar present in milk is produced from the glycosidic linkage of galactose and glucose. The anomeric carbon atom of beta-galactose is attached to the 4th hydroxy group of glucose through beta-1, 4 glycosidic linkage.
Galactose an epimer of glucose is produced in the initial steps when glucose is activated by UDP to form UDP-glucose it can be epimerized to Galactose.
When a galactose subunit is combined with another glucose units through a glycosidic linkage it forms a disaccharide Lactose.
Answer:
Zero-Order
Explanation:
The exothermic decaying of nitrous oxide at 575° C will lead to as follows:
→
<u>Hot platinum wire in the above reaction would function as a catalyst in the zero-order</u>. However, if the reaction is considered in the gaseous phase, it will be more inclined towards second-order.
In the given scenario( → ), <u>the reactant molecules of Nitrous oxide are restricted to the ones which have linked themselves to the catalyst's surface. Once this limited surface is filled, the extra molecules of gas would remain vacant until the previously attached molecules with the surface are decayed entirely</u>.
Effusion rate, R, is inversely proportional to the square root of the molar mass, M:
R α 1 / √M
Let Ra be the effusion rate of a gas with molar mass Ma and Rb the efussion rate of a gas with molar mass Mb, then:
Ra / Rb = √ [Mb / Ma]
You know Ra / Rb = 1.82 and Ma = molar mass of N2 = 28.02 g/mol
=> Mb = [Ra / Rb]^2 * Ma = (1.82)^2 * 28.02 g/mol = 92.81 g/mol
Answer: 92.81 g/mol

Explanation:
The correct electronic configuration of chromium is; [Ar] 3d⁵ 4s¹
The correct electronic configuration for Zr is; [Kr] 4d² 5s²
The correct electronic configuration of Cu^+ is; [Ar] 3d¹⁰
The electronic configuration of an atom refers to the arrangement of electrons in the atoms of such element.
The appropriate number of electrons and its properly written electronic configuration is clearly shown in this answer.
