Answer:
Chemical energy is energy stored in the structure of molecules within the bonds between atoms. Energy can be added or released from a molecule by changing the arrangement of electrons (rearranging chemical bonds).
Explanation:
Answer:
<h3>The answer is 8.40 g/mL</h3>
Explanation:
The density of a substance can be found by using the formula
volume = final volume of water - initial volume of water
volume = 56.4 - 50 = 6.4 mL
We have
We have the final answer as
<h3>8.40 g/mL</h3>
Hope this helps you
Baking powder solution has an effect on a diluted hydrochloric acid solution by causing the release of carbon dioxide from sodium bicarbonate, a component of baking soda.
One molecule of backing soda + one molecule of hydrochloric acid yields one molecule of sodium chloride (table salt) + one molecule of carbon dioxide + one molecule of water.
HCl + NaHCO₃=NaCl+H₂CO₃
However, carbonic acid is quite unstable:
H₂CO₃ = CO₂ + H₂O
HCl + NaHCO₃ = NaCl + H₂O (Water) + CO₂.
Effervescence, which is a fast bubble formation, is how liquid releases CO2.

Answer:
Sulfur, phosphorus, silicon, and chlorine are common examples of elements that form an expanded octet.
Explanation:
Phosphorus pentachloride (PCl5) and sulfur hexafluoride (SF6) are examples of molecules that deviate from the octet rule by having more than 8 electrons around the central atom
Gaseous Matter is composed of composed particles that's packed loosely & does not have a defined shape or volume.
