Element X with atomic number 10 and atomic mass 21
Element Y with atomic number 11 and atomic mass 21
Element Z with atomic number 10 and atomic mass 22
Element M with atomic number 12 and atomic mass 21
Answers
Answer:
Element X with atomic number 10 and atomic mass 21
Element Z with atomic number 10 and atomic mass 22
Explanation:
Isotopy is the existence of two or more atoms of the same element having the same atomic number but different mass numbers due to the differences in the number of neutrons in their various nuclei.
Isotopes of an element have the same electronic configuration. They share the same chemical propertiesThey only differ in their masses.So, Element X and Z with atomic number 10 which is their number of electrons are isotopes. Their mass number, 21 and 22 differs.
The enzyme known as alcohol dehydrogenase is capable of oxidizing ethanol, methanol and other hydroxyl group containing organic compounds into their corresponding aldehydes. Such an enzyme with ___ catalyzes the reaction of structurally related substances.
Answers
Answer:
Relative specificity.
Explanation:
Relative specificity can be defined as a phenomenon whereby molecules in a biochemical environment interacts or relates differentially with a large number of its partner, target, or substrate and as such affecting them respectively depending on each partner, target or substrate.
An enzyme refers to a biological catalyst that is typically used to speed up (accelerate) the rate of a chemical reaction by lowering the activation energy of its reactants.
The enzyme known as alcohol dehydrogenase is capable of oxidizing ethanol, methanol and other hydroxyl group containing organic compounds into their corresponding aldehydes. Such an enzyme with relative specificity catalyzes the reaction of structurally related substances known as substrates with similar structures and bonds.
Analyze: The first shell can hold a maximum of two electrons. How does this explain the valence of hydrogen
Answers
Answer:
See explanation
Explanation:
Hydrogen has a valency of +1 or -1. Its electronic configuration is 1s1.
The 1s sub-level (first shell) is known to hold two electrons. This means that hydrogen may either loose this one electron in the 1s level to yield H^+ or accept another electron into this 1s level to form H^- (the hydride ion).
The formation of the hydride ion completes the 1s orbital.
