Explain how redox reactions are involved in energy exchanges

Chemistry
1 answer:
ankoles [38]2 years ago
3 0

Redox reactions involve one substance losing electrons (oxidized) and another substance gaining electrons (reduced) in the same reaction. As electrons are transferred between substances, the electrons lose potential energy and energy is released.

How many moles of K+ and PO4^3- ions are present in 20.0 mL of a 0.015 M solution of potassium phosphate?
Romashka-Z-Leto [24]

Answer:

n_{K^+}=0.0009molK^+

Explanation:

Hello,

In this case, the first step is to compute the number of moles of potassium phosphate in 20.0 mL (0.020L) of the 0.015-M (mol/L) solution as shown below:

n=0.020L*0.015\frac{mol}{L}=0.0003mol

Thus, these moles correspond to potassium phosphate moles, which molecular formula is K₃PO₄, therefore, one mole of this compound contains three moles of potassium ions as it has three as its subscript in the formula. Thereby, the moles of potassium ions result in:

n_{K^+}=0.0003molK_3PO_4*\frac{3molK^+}{1molK_3PO_4} \\\\n_{K^+}=0.0009molK^+

Best regards.

Distillation is a method that depends on differences in the boiling points of liquids to separate the components of a liquid mix
ryzh [129]

Explanation:

for immiscible liquids it is quite easy to separate and the separating funnel can be used but for miscible liquid they form a single entity and separating them is quite impossible if the differences in temperature is not considered,so in distillation the one with lower boiling point evaporates out living behind the one with high boiling point
