The answer is B) fills all the space in its container
Answer:
On both sides of the equation, there are 5 atoms of H
Explanation:
H₂ is a dyatomic molecule, so it has 2 atoms.
In ammonia, there are 3 atoms of H plus 1 atom of N.
Answer:
Explanation:
Hello,
In this case, for us to compute the absorbed heat, we apply the following equation:
Whereas we use the mass, specific heat and temperature change for the piece of aluminium, thus, we obtain:
It is positive as the heat is entering, therefore the temperature raises.
Best regards.
Answer:
Sulfur
Explanation:
A non-metal in the third period that should have chemical properties similar to oxygen is sulfur.
This is because elements in the same group/family have similar chemical properties.
- Chemical properties is predicated on the number of valence electrons within an atom.
- The number of valence electrons is the number of outermost shell electrons within an atom.
- Elements combines with one another using these valence shell electrons.
- Since sulfur is in the third period and the same vertical group as oxygen, they have similar chemical properties.
