Properties of covalent solids?
# Gases, liquids, or solids (made of molecules) # Low melting and boiling points # Poor electrical conductors in all phases # Many soluble in nonpolar liquids but not in water Pretty sure this right
What are some characteristic of most covalent compounds?
Most covalent compounds have low melting and boiling points, are usually gases or liquids at room temperature, and tend to be poor conductors of electricity. They also have localized bonds between nonmetal atoms, where electrons are shared.
What are the physical properties of nonmetals?
Poor conductors of heat and electricity.Brittle - if a solid.Nonductile.Do not possess metallic luster.Transparent as a thin sheet.Solids, liquids or gases at room temperature.
Which of the following is a characteristic of nonmetals?
- lower density- lower hardness- lower melting point- lower boiling point- some nonmetals are gaseous or liquidsetc.
What are the typical physical properties of substances that have metallic ionic and covalent bonds?
Metallic: melting point @ 63, boiling point @ 760, properties: soft, silvery, solid, and conductor as a solid. Covalent: melting point @ -101, boiling point @ -34.6, properties: greenish yellow gas and not a good conductor.
How can poor technique affect performance?
Poor technique can affect performance by if gymnastics, diving, etc; you will definetly lose points if done professionally. With a sport like baseball, football, soccer, basketball, etc; poor technique can affect the shot/throw/catch/pass etc.
What technique often results in poor farmland?
Slash and burn

Why does your ink fall out of your tattoos?
Poor application technique combined with poor ink quality both contribute to this phenomenon.

Why should you never poor hot liquids into a cold drinking glass?
Because the glass shatters
Why are the flowers falling of the capsicum?
The flowers will fall after pollination or this can be caused by poor watering technique.
How poor laboratory technique?
explain why labortory safety is every one's concern. explain is a compare and contrast format, how poor labortory technique can lead to inaccurate results. why can we not just dump chemicals down the sink after we complete our laboratory experiment?
When looking at a Soldier with poor standing posture the MFT analysis?
facial expressions
How can a poor swot analysis affect strategic planning?
A poor swot analysis can impact strategic planning by highlighting the wrong opportunities. If the wrong opportunities, or threats are identified, then the company will make the wrong moves within the industry.
Why is micropropagation expensive?
Micropropagation is a technique, which is used to propagate plants that are (1) Threatened/endangered (2) Difficult to propagate conventional methods (3) Poor seed availability (poor sexual reproduction) The reason behind the use of the technique varied depends upon user/plant. The technique is not a expensive one when it used properly.
