Answer:
When the Zebra arrived they ate all the food so the Unionid mussels declined as they died from the lack of food. Causing the Zebra Zebra numbers to increase and Unionid numbers to decline.
Q unknown = -Q H2O
Q H2O= (100g x 4.18 J/g C x (25C - 20C)
Q H2O = 2090J
-2090J = (50g x c x (25C-90C)
-2090J = -3250c
.64 = c
I am a high school student and have done this problem a few months ago for my test, hope this helps
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.
