if burning wood causes the energy of the surroundings to increase by 12,000J what is the change in energy of the wood
Hitman42 [59]
Due to the law of conservation of energy we know that the energy that heated the surrounding had to have come from the reaction which means that the wood (with oxygen since this is combustion) lost 12000J. The change in energy for the wood is negative. I hope this helps. Let me know if anything is unclear.

Metallic ions are best described as: anions giving up electrons and attracting each other anions together in a sea of electrons
Alex73 [517]

Answer: cations together in a sea of electrons

Explanation:

Metallic bonding is the type of chemical bonding occurs between the atoms of a metals. In this type of bonding arises due to electrostatic interaction between the electron cloud of de-localized electrons with positively charges metal ions called as cations.

These de-localized electrons are the valence electrons of metal atoms which are shared between them.

In ionic bonding , the cations are attracted to anions where cations are formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.
