Nonmetals have properties opposite those of the metals. The nonmetals are brittle, not malleable or ductile, poor conductors of both heat and electricity, and tend to gain electrons in chemical reactions. Some nonmetals are liquids. These elements are shown in the following figure.
A)Calcium-This because calcium has two valence electrons hence it is a metal therefore it will form an ionic bond with carbon.
Answer:
60.87 ft/s
Explanation:
Speed is defined as a ratio between the distance traveled and time. Given a total distance of:
![d = 166.0~mi](https://tex.z-dn.net/?f=d%20%3D%20166.0~mi)
Let's convert it into feet first of all using the conversion factor:
![1~mi = 5280~ft](https://tex.z-dn.net/?f=1~mi%20%3D%205280~ft)
We obtain:
![d = 166.0~mi\cdot \frac{5280~ft}{1~mi} = 876480~ft](https://tex.z-dn.net/?f=d%20%3D%20166.0~mi%5Ccdot%20%5Cfrac%7B5280~ft%7D%7B1~mi%7D%20%3D%20876480~ft)
Now let's convert the given time into seconds knowing that:
![1~h = 3600~s](https://tex.z-dn.net/?f=1~h%20%3D%203600~s)
Then:
![t = 4.000~h\cdot \frac{3600~s}{1~h} = 14400~s](https://tex.z-dn.net/?f=t%20%3D%204.000~h%5Ccdot%20%5Cfrac%7B3600~s%7D%7B1~h%7D%20%3D%2014400~s)
Now let's find the speed:
![v = \frac{d}{t} = \frac{876480~ft}{14400~s} = 60.87~ft/s](https://tex.z-dn.net/?f=v%20%3D%20%5Cfrac%7Bd%7D%7Bt%7D%20%3D%20%5Cfrac%7B876480~ft%7D%7B14400~s%7D%20%3D%2060.87~ft%2Fs)
Answer:
Layer A is the youngest
It is at the top, it has all of the dinosaur bones which got buried after earth got hit with an asteroid and they went extinct. Layer D started it and all of these years dirt, soil, and fossils have been gathering making each layer before older and older.
I need brainliest to rank up
Explanation:
Calcium chloride is the salt of hydrochloric acid and calcium hydroxide. Calcium hydroxide is usually not considered a strong base, and I believe this is because of it's low solubility. HCl is a strong acid, and so the salt should be slightly acidic.
