Answer:
The length of the bond is determined by the number of bonded electrons (the bond order). The higher the bond order, the stronger the pull between the two atoms and the shorter the bond length. Generally, the length of the bond between two atoms is approximately the sum of the covalent radii of the two atoms.
No idea , sorry. maybe it is.....actually i dont know, sooo sorry
Answer:
1100mL
Explanation:
V of a rectangular prism = l*w*h
= 12cm*20cm*5cm
=1100cm^3
1 cm^3 = 1mL
so 1100cm^3 = 1100mL
<u>Answer:</u> The final temperature of the system is 14.60°C
<u>Explanation:</u>
When metal is dipped in water, the amount of heat released by metal will be equal to the amount of heat absorbed by water.
The equation used to calculate heat released or absorbed follows:
![m_1\times c_1\times (T_{final}-T_1)=-[m_2\times c_2\times (T_{final}-T_2)]](https://tex.z-dn.net/?f=m_1%5Ctimes%20c_1%5Ctimes%20%28T_%7Bfinal%7D-T_1%29%3D-%5Bm_2%5Ctimes%20c_2%5Ctimes%20%28T_%7Bfinal%7D-T_2%29%5D)
......(1)
where,
q = heat absorbed or released
= mass of aluminium = 25.00 g
= mass of water = 100 g
= final temperature = ?°C
= initial temperature of aluminium = 100°C
= initial temperature of water = 10°C
= specific heat of aluminium = 0.900 J/g°C
= specific heat of water= 4.18 J/g°C
Putting values in equation 1, we get:
![25\times 0.900\times (T_{final}-100)=-[100\times 4.18\times (T_{final}-10)]](https://tex.z-dn.net/?f=25%5Ctimes%200.900%5Ctimes%20%28T_%7Bfinal%7D-100%29%3D-%5B100%5Ctimes%204.18%5Ctimes%20%28T_%7Bfinal%7D-10%29%5D)
Hence, the final temperature of the system is 14.60°C
Answer:
The answer to your question is: Includes sulfur and gain two electrons
Explanation:
Includes Chlorine This option is wrong, Chlorine belongs to group VII.
Includes Sulfur This option is true, Group VI includes Oxygen, Sulfur, Selenium, Tellurium.
Gain 2 electrons
. This option is true, Elements in group VI have six valence electrons so they gain to electrons to become estable.
Tend to form +2 ions This option is wrong, this elements form -2 ions
Have 5 valence electrons This option is wrong, this elements have 6 valence electrons.
