I think it would be Bromine and Mercury, hope that helps
Size, speed and angle of the falling object determine the size shape and complexity of the resulting crater
Answer:
Final temperature = 
Explanation:
Given that,
Heat added, Q = 250 J
Mass, m = 30 g
Initial temperature, T₁ = 22°C
The Specific heat of Cu= 0.387 J/g °C
We know that, heat added due to the change in temperature is given by :
Put all the values,
So, the final temperature is equal to .
S. Properties can be anything from composition to color to ductility. Without knowing an object's properties, it is impossible to characterize it. For example, looking at some common properties of metals helps to differentiate them from non-metals or metalloids.
1. 8
2. It's a Noble gas
3. No because it doesn't need any more electrons
4. Physical - odorless yellow inflammable and conductive when it's a plasma
Chemical - unstable
