2 C5H12O + 15 O2 = 10 CO2 + 12 H2O
Hope this helped :)
Ions bound together by electrostatic attraction form ionic crystals. ... A simple cubic crystal lattice has ions equally spaced in 3D at 90° angles. Stability of ionic solids depends on lattice energy, which is released in the form of heat when two ions are brought together to form a solid.

Answer:
2365.0 g
Explanation:
First we <u>convert 1.2 x 10²⁵ particles into moles</u>, using <em>Avogadro's number</em>:
- 1.2 x 10²⁵ particles ÷ 6.023x10²³ particles/mol = 19.9 mol
Then we <u>convert 19.9 moles of NiCO₃ into grams</u>, using the <em>molar mass of NiCO₃</em>:
- NiCO₃ Molar Mass = 118.702 g/mol
- 19.9 mol * 118.702 g/mol = 2365.0 g
Answer:
Chemical laws are those laws of nature relevant to chemistry. The most fundamental concept in chemistry is the law of conservation of mass, which states that there is no detectable change in the quantity of matter during an ordinary chemical reaction. Modern physics shows that it is actually energy that is conserved, and that energy and mass are related; a concept which becomes important in nuclear chemistry. Conservation of energy leads to the important concepts of equilibrium, thermodynamics, and kinetics.
