<span>The reaction of a burning candle gives off heat and is an exothermic reaction. It does not absorb heat because it does not cool down its surroundings as the candle burns. The answer is the reaction of a burning candles gives off heat.</span>
Answer:
the wheels and force of your foot pushing off of the ground.
When a beta particle<span> is emitted from the </span>nucleus<span> the </span>nucleus<span> has one more proton and one less neutron. This means the </span>atomic<span> mass number remains unchanged and the </span>atomic<span> number increases by 1.
Best answer :
</span><span>b. the number of electrons in the atom increases by one as the beta particle leaves the nucleus and joins the valence electrons</span>
Answer:
It does not have a regular composition.
Explanation:
P: Good conductor of heat and electricity - R: the delocalized electrons are
free to move around the structure
P: High melting and boiling points - R: the bonds in metals are very strong
P: Ductile (can be stretched and squashed) - R: because the electrons are free to move, the atoms can slide over each other.
P: Malleable (can be hammered into shape) - R: the bonds in metal don't break easily
