Answer:
The battery of a phone contains stores chemical energy. This energy is converted into electrical energy primarily when the phone is turned on. The chemical energy is also converted into light energy, sound energy and heat energy. With the passage of time, the energy will be changed back into the chemical energy when we will charge the phone again.
Answer:
HCOOH(aq) + OH-(aq) —> HCOO-(aq) + H2O(l)
Explanation:
HCOOH is a weak acid and so will not ionised completely in solution.
KOH is a strong base and will ionised completely as shown below
KOH(aq) –> K+(aq) + OH-(aq)
The overall reaction can be written as follow:
HCOOH(aq) + K+(aq) + OH-(aq) —> HCOO-(aq) + K+(aq) + H2O(l)
Cancel out the K+ to obtain the net ionic equation as shown below
HCOOH(aq) + OH-(aq) —> HCOO-(aq) + H2O(l)
The answer is A.
Gravity acting on the edges of plates and convection in the mantle

I don't know sorry ok I have some work so I m sorry
Answer:
<span>The strongest intermolecular interactions between hydrogen fluoride (hf) molecules arise from Hydrogen Bonding.
Explanation:
Hydrogen Bond interactions are considered the strongest intermolecular interactions among molecules. These interactions are found between Hydrogen atom of one molecule bonded to most electronegative atoms (i.e F, O, N) and the most electronegative atoms of neighbor molecule.
In case of HF, fluorine has the greatest electronegativity of 4, so the hydrogen bonded to Fluorine becomes partial positive and makes Hydrogen bond with Fluorine atom of </span>neighbor HF molecule.<span />
