Examples include carbonated water (i.e. soda water); honey; sugar syrup (used in confectionery); supersaturated drug delivery systems. "SDDS"; and sodium acetate solutions prepared from 160 g NaOAc and 30 mL water.
Answer:
The reaction is endothermic
Explanation:
we know that the reactants had to get energy from its surroundings which means that the reaction is endothermic
Answer:
ga
Explanation:
beacuse it its the voltage that high
Sample cost = $15.796
<h3>Further explanation</h3>
Given
Mass = 2 g
Density = 0.718 g/ml
Cost = $5.67 per mL
Required
Cost
Solution
The density : the ratio of mass and volume
Can be formulated :
Density (ρ) = m : V
The volume of the liquid :
V = m : ρ
V = 2 g : 0.718 g/ml
V = 2.786 ml
Sample cost :
= 2.786 ml x $5.67/ml
= $15.796
Nitric acid (HNO₃) is a strong acid. Hence, it completely dissociates into ions as H⁺ and NO₃⁻ in water.
The balanced equation is;
HNO₃(aq) →H⁺(aq) + NO₃⁻(aq)
The stoichiometric ration between HNO₃(aq) and H⁺(aq) is 1 : 1
Hence, the [H⁺] = <span>3.76 x 10</span>⁻²<span> M</span>
