Answer:
c. An ionic bond is much stronger than most covalent bonds
Explanation:
Ionic bonds are interatomic bonds that forms as a result of electrostatic attraction between two ions. For an ionic bond to be formed, one atom must have lost or gained electron from another that is transferring it. Ionic bonds typically form between atoms whose electronegativity differences are far apart.
Ionic bonds are usually stronger than other types of bonds due to the electrostatic attraction between ions.
One very distinct feature about ionic compounds is that they are conductors of electricity in either molten or aqueous. At room temperature, they are solids and contains no mobile ions.
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.

Answer:
Explanation:
mass fraction N₂ : He : CH₄ : C₂H₆ : : 15 : 5 : 60 : 20
mole fraction N₂ : He : CH₄ : C₂H₆ : : 15/28 : 5/4 : 60/16 : 20/30
mole fraction N₂ : He : CH₄ : C₂H₆ : : .5357 : 1.25 : 3.75 : .67
Total mole fractions = .5357 + 1.25 + 3.75 + 0.67 = 6.2057
mole fraction of N₂ = .5357 / 6.2057 = .0877
mole fraction of He = 1.25 / 6.2057 = .20
mole fraction of CH₄ = 3.75 / 6.2057 = .6043
mole fraction of C₂H₆ = .67 / 6.2057 = .108
Partial pressure = total pressure x mole fraction
Partial pressure of N₂ = 1200 kPa x .0877 = 105.24 kPa
Partial pressure of He = 1200 kPa x .20 = 240 kPa
Partial pressure of CH₄ = 1200 kPa x .6043 = 725.16 kPa
Partial pressure of C₂H₆ = 1200 kPa x .108 = 129.6 kPa
Abiotic things are like rocks...dirt...water vs. biotic is living things or something that was living
