Water, H2O, is a molecule made of oxygen and hydrogen. The bonds that hold water molecules together are due to shared __________
adell [148]

Oxygen and hydrogen share electrons in the molecule of water to form covalent bonds.

<h3>What kinds of bonds exist?</h3>
  • Covalent bonds: These are formed between nonmetals and electrons by sharing electrons.
  • Ionic bonds: These are formed between metals, which lose electrons, and nonmetals, which gain electrons.
  • Metallic bonds: There are formed between metals. Electrons are delocalized in a cloud.

Water, H₂O, is a molecule made of 2 nonmetals: oxygen and hydrogen. The bonds that hold water molecules together are due to shared electrons, and known as covalent bonds.

Oxygen and hydrogen share electrons in the molecule of water to form covalent bonds.

This is the chemical formula for carvone (the chemical that gives spearmint its flavor): An organic chemist has determined by me
xz_007 [3.2K]

The given question is incomplete. The complete question is :

This is the chemical formula for carvone (the chemical that gives spearmint its flavor) C_{10}H_{14}O: An organic chemist has determined by measurements that there are 27.3 moles of carbon in a sample of carvone. How many moles of oxygen are in the sample

Answer: 2.73 moles of oxygen are there in the sample.

Explanation:

The chemical formula of carvone is C_{10}H_{14}O.

This means:

When 10 moles of carbon are there in carvone , 1 mole of oxygen is there in carvone

Thus for 27.3 moles of carbon in carvone , \frac{1}{10}\times 27.3=2.73 mole of oxygen is there in carvone.

Thus 2.73 moles of oxygen are there in the sample.

Describe the shapes and relative energies of the SPD &amp; f atomic orbitals
Deffense [45]

Explanation:

The shapes and relative energies of the orbitals s,p,d and f orbitals are given by the principal quantum number and the azimuthal quantum number.

The principal quantum number gives the main energy level and the azimuthal quantum number denotes the shape of the orbitals.

  • For the principal quantum number, they represent the energy levels in which the orbital is located or the average distance of the orbital from the nucleus. It takes the number n = 1,2,3,4,5,6,7......
  • The azimuthal quantum number(L) shows the shape of the orbitals in subshells accommodating electrons. The number of possible shapes is limited by the the principal quantum number.
