Answer:
bromine
Explanation:
Any element in the halogen group will have seven valence electrons. These elements include fluorine, chlorine, bromine, iodine, and astatine
The statement '<span>The more particles a substance has at a given temperature, the more thermal energy it has' is true. </span><span>The
kinetic molecular theory of gases has three main laws and one of them is the
average kinetic energy of the particles in a gas. The average kinetic energy of
the gas particles is the behavior and movement it does in the surroundings. It
is directly proportional to temperature wherein if you increase the
temperature, the kinetic energy of a particle also increases. It will also
decrease its movement or its kinetic energy if the temperature lowers. </span>
Explanation:
In a heat exchange, the temperature change is inversely proportional to the specific heat capacity. Since substance A has a heat capacity that is much greater than that of substance B, the temperature change of substance A will be less than the temperature change of substance B. Therefore, the final temperature is closer to that of 
than 
.
Answer: 75.02 m
Explanation:
u = 0 ( starts from rest )
v = 50 m/s
t = 3 s
( i ) a = v - u / t
= 50 - 0 /3
= 16.67
( ii ) s = ut + 1/2 at²
= 0 × 3 + 1/2 × 16.67 × 3 × 3
= <u>75.02 m</u>
