The more electrons that are shared between two atoms, the stronger their bond will be. Covalent bonding is an example.
Answer:
The mass of silver block = 73.95 g
Explanation:
Given,
For water:
Mass = 100.0 g
Initial temperature = 24.8 °C
Final temperature = 26.2 °C
Specific heat of water = 4.184 J/g°C
For silver:
Mass = x g
Initial temperature = 59.4 °C
Final temperature = 26.2 °C
Specific heat of water = 0.2386 J/g°C
Heat gain by water = Heat lost by silver
Thus,
Where, negative sign signifies heat loss
Or,
So,
<u>Hence, the mass of silver block = 73.95 g</u>
If a large leak of refrigerant occurs such as from a filled cylinder in an enclosed area, the correct action that should be taken when no self-contained breathing apparatus is available would be to vacate the spill area and ventilate it. Leaving the area of the spill should be done as fast as possible to avoid suffocation of the refrigerant or other health effects like burns and irritations. Also, diluting it with air or ventilating it would make it less harmful to the people affected by the spill as it would be less harmful than being in its concentrated form.
