Archy [21]

Answer:

Mendel, Inheritance/Heredity

Explanation:

Gregor Mendel (1822-1884) was an Austrian monk and scientist as stated in this question. He is referred to as the FATHER OF GENETICS due to his immense contributions to the principle of inheritance.

Gregor Mendel via his several works conducted on pea plants was able to demonstrate how traits passed down from parents to offsprings in a process called INHERITANCE OR HEREDITY.

Compound 2 contains 2.0g of hydrogen and 32.0g oxygen. What is the percent compound of each element?
Dmitriy789 [7]

Note down the formula below

\boxed{\sf Mass\%\;of\; element=\dfrac{Mass\:of\:the\: element}{Mass\;of\:the\: compound}\times 100}

Mass of the compound

\\ \sf\longmapsto 32+2=34g

Mass % of Hydrogen:-

\\ \sf\longmapsto \dfrac{2}{34}\times 100

\\ \sf\longmapsto \dfrac{1}{17}\times 100

\\ \sf\longmapsto 5.8\%

Mass % of Oxygen:-

\\ \sf\longmapsto \dfrac{32}{34}\times 100

\\ \sf\longmapsto \dfrac{16}{17}\times 100

\\ \sf\longmapsto 94.2\%

Select the correct answer.
Serjik [45]

Ionic bond is a chemical bond formed by the complete transfer of electrons between two atoms. The atom that loses electrons gains a positive charge (cation) and that which accepts electrons gains a negative charge (anion). Now, electronegativity is a parameter that measures the tendency of an atom to accept electrons. In the context of ionic bonding, two elements which show a significant difference in their electronegativity values form ionic bonds.

In the given examples, the difference in electronegativity is greatest between K  and Br i.e. 0.8 and 2.8 respectively with a difference of 2.0. This also makes sense since K and Br are on the extreme ends of the periodic table. Hence, potassium with a valence electron configuration of 4s1 will lose its s electron to Br (4s24p6) and form an ionic molecule K⁺Br⁻

Ans E) potassium and bromine
