Answer:
SI unit: kg/m³
but g/cm³ is commonly used
Explanation:
Atoms are related to balancing equations because the amount of atoms on the left of the equation (reactants) needs to be the same amount on the right (products).
For example, 2H₂ + O₂ → 2H₂O
If you count the amount of hydrogen atoms on both sides each, there would be 4 (make sure to multiply the coefficient by the subscripts).
If you count the amount of oxygen atoms on both sides each, there will be 2 of them (2 in a molecule of oxygen)

<h2>Answer:</h2>
The option B is correct option. Which is release of heat and/or light energy .
<h3>Explanation:</h3>
According to the definition of exothermic reaction :
<em>An exothermic reaction is a chemical reaction that releases energy by light or heat.</em>
From definition option B (release of heat and/or light energy) indicates that an exothermic reaction has taken place.
.
Because potassium is a gas that can evolve
Boiling point of
glucose = 150°C
AlCl3 = 180°C
NaCl = 1,413°C
CaCl2 = 1,935°C
Therefore, the one with the lowest boililng point is glucose
