Answer: 209.2
Explanation:
4. q = mcat
q = 5g(4.184)(40-50)
q = -209.2
the negative sign indicates that heat is given off
Answer:Metallic bonding As you can see, an electron is freely moving from one atom to another. As one metal atom loses an electron and becomes a positively charge ion, it immediately accepts one from another to become a neutral atom. This back and forth losing and gaining of electrons among atoms of the metal allow metals to easily conduct electricity.

Answer:
HBr
Explanation:
Acidity is directly proportional to non metallic character. Moving from left to right and down the group non metallic character increases hence acidic strength increases. Based on this explanation HBr is strongest acid among given compounds.
It's -Bohr's Model- becuase Dalton I dont think did a model. Thomson's was the "Plum Pudding Model." Ernest Rutherford drew one out(I dont know i dont have a model down though) so it the only one left is Dalton's Model which is it. (Hopefuly)
The thermal energy of a substance is related to the movement of the particles in the substance. This energy is defined by the temperature of the substance and whether heat is transferred or lost. This can be explained as a higher temperature causes the particles in substances to move faster and collide.
