Answer : The correct option is, 11.77 L
Solution : Given,
Mass of bromine gas = 84 g
Molar mass of bromine gas = 159.8 g/mole
First we have to calculate the moles of bromine gas.
Now we have to calculate the volume of bromine gas at STP.
As we know that at STP,
1 mole of bromine gas contains 22.4 L volume of bromine gas
So, 0.5256 mole of bromine gas contains 
volume of bromine gas
Therefore, the volume of bromine gas at STP is, 11.77 L
Answer :
The steps involved in the lewis-dot structure of 
are :
- First we have to determine the total number of valence electron in .
Number of valence electrons in S = 6
Number of valence electrons in two F atom = 2(7) = 14
Total number of valence electrons = 6 + 14 = 20 electrons
- Placing a bonding pair of electrons between the atoms to form the chemical bonds.
Electrons used in bonding = 4
- The remaining electrons are used as a lone pair for central or terminal atoms to achieve an octet to finish the Lewis dot structure.
Electrons used as a lone pair = 20 - 4 = 16
The image is shown below.
D - it is the number of protons in the nucleus
Answer:
= 8350 joules
Solution and explanation:
- The heat of fusion refers to the quantity of heat released when a given amount of water freezes.
- For example, 1 g of water releases 334 J when it freezes at 0°C.
Therefore; For 25.0 g of water.
Heat released = Mass of water × heat of fusion
= 25 g × 334 J/g
= 8350 Joules
Hence, the amount of heat released when 25.0 g of water freezes at 0°C is 8350 J.
