Answer:
Have high melting points and high boiling points.
Explanation:
- Covalent bonds are types of chemical bonds that result from the sharing of electrons between non-metal atoms.
- Covalent bonds result in the formation of covalent compounds.
- Covalent compounds are characterized by low melting and boiling points.
- Therefore, it won't be true to say they have high melting and boiling points.
- Other properties of covalent bonds include poor conductors of electricity and heat, gases or liquids at room temperature, and are non-polar compounds among others.
Answer:
1 mole of Al2O3 = 102 grams
1 mole of Al2 = 54 grams
102 grams of Al2O3 contains = 54 gram of Al2
10kg of Al2O3 contains = (54/102)*10000g Al2
= 5294.11 g Al2 or 5.29411 kg
Answer:
Water moves from the ground or oceans into the atmosphere through a process called evaporation. It's a process that happens on a molecular level when the molecules of water are really energized and rise into the air. Now you've got water in the air and water on land. Organisms all over the Earth need water to survive.
Explanation:
For part of our orbit the northern half of Earth is tilted toward the Sun. This is summer in the northern hemisphere; there are longer periods of daylight, the Sun is higher in the sky, and the Sun's rays strike the surface more directly, giving us warmer temperatures.
Answer:
Pelting point.
Explanation:
Freezing point is the same is the melting point.
