Answer:
chemical and nuclear reaction
Explanation:
Answer:
Gases mix easily because of their high kinetic energy and low inter-molecular forces.
Explanation:
Single Replacement & Decomposition
<h3>Further explanation</h3>
Given
Two chemical reactions
1. Cl2 + 2NaBr ⇒2NaCl + Br2
2. 2NaCl ⇒2Na + Cl2
Required
Type of reaction
Solution
Equation 1 : A single replacement reaction is a chemical reaction in which one element replaces the other elements of a compound to produce new elements and compounds
General formula :
A + BC ⇒ AC + B
Equation 2 : the decomposition reaction of a compound into its constituent elements or compounds
General formula :
AB ⇒ A + B
Supposing complete ionization:
<span>CaCl2 → Ca{2+} + 2 Cl{-} [three ions total] </span>
<span>(1.56 m CaCl2) x (3 mol ions / 1 mol CaCl2) = 4.68 m ions </span>
<span>(1.86 °C/m) x (4.68 m) = 8.70 °C change </span>
<span>0°C - 8.70°C = - 8.70°C</span>
