H2O bond length is 95.84 pm while H2S bond length is 133.6 pm. The atomic size and bond length for H2O is less than that of H2S. Co2 bond length is 116.3 pm while CS2 bond length is 155.3 pm.
Explanation:
A covalent bond is defined as the occurrence of a bond due to the sharing of electrons between the combining atoms.
Atomic number of hydrogen atom is 1 and its electronic configuration is . So, in order to complete its octet it needs to gain or mutually shares one electron.
A covalent bond is generally formed between non-metal atoms.
Thus, we can conclude that hydrogen has only one electron that will be involved in the formation of a covalent bond.
Answer:
Answer is option D
Explanation:
resistance of movement between two surfaces in contact
Answer is: 12 grams of the isotope carbon-12 (¹²C).
The Avogadro’s number is the number of atoms in 12 grams of the isotope carbon-12 (¹²C).
Na is Avogadro number or Avogadro constant (the number of particles, in this example carbon, that are contained in the amount of substance given by one mole).
The Avogadro number has value 6.022·10²³ 1/mol in the International System of Units; Na = 6.022·10²³ 1/mol.
Answer:
you can solve the rest of the equation. I only reduced it to that much to show you how to derive it
