Answer:
A safety guide lines are rules and regulations that are made to make sure place is safe and conducive for everyone.
Given mass of Scandium = 50.0 g
Increase in temperature of the metal when heated = 
Heat absorbed by Scandium = 
The equation showing the relationship between heat, mass, specific heat and temperature change:
Where Q is heat =
m is mass = 50.0 g
ΔT =
On plugging in the values and solving for C(specific heat) we get,
=50.0g(C)()
C = 0.491
Specific heat of the metal = 0.491
Answer:
The correct option is;
Cathode rays are deflected towards a positively charged rod
Explanation:
Cathode rays are beam of electrons emitted from the cathode in a vacuum tube and moving towards the anode, due to the difference in the voltage between the electrodes
The discovery of the electrons was through the proof by Thomson that cathode rays were a negatively charged, previously unknown particle, which was to become known as the electron.
Ability to adapt to their environment?? there isn't much context to the question /:
Answer:
Aluminium metal reacts vigorously with all the halogens to form aluminium halides. So it reacts with chlorine, bromine, and iodine.
