Sorry, I don't have one for now. I remember answering this a while ago, but I don't remember the exact reason why it's 3+.
Answer : 4.8 florins can you exchange for your 4 guilders.
Solution : Given,
The current exchange rate for every 2.4 florins is 2.0 guilders
As per question,
The exchange rate is 2.0 guilders for every 2.4 florins
The exchange rate is 1 guilders for every 
florins
The exchange rate is 4 guilders for every 
florins
Therefore, the 4.8 florins can you exchange for your 4 guilders.
Explanation:
Balanced chemical reaction equation will be as follows.
In human body, the neutral iron changes into 
(aq) cation. There will be an oxidation-half reaction and a reduction-half reaction. Equations for this reaction are as follows.
Oxidation: 2Fe^{2+}(aq) \rightleftharpoons 2Fe^{3+}(aq) + 2e^{-}[/tex] .... (1)
Reduction: 
...... (2)
On adding both equation (1) and (2), the overall reaction equation will be as follows.
Therefore, neutral iron is a part of Heme - b group of Hemoglobin and in an aqueous solution it dissolutes as a part of Heme group. Hence, then it becomes an cation.
Answer:
Earth's gravity is strong enough to hold onto its atmosphere and keep it from drifting into space.
Answer :
An egg cooking is an endothermic reaction.
A candle burning and Plaster & water combining and becoming warm are exothermic reaction.
Salt being added to water, with no change in temperature neither endothermic nor exothermic reaction.
Explanation :
- Endothermic reaction : It is a type of reaction in which energy is absorbed in the form of heat from the surroundings.
- Exothermic reaction : It is a type of reaction in which energy is released in the form of heat from the system.
An egg cooking : In this process, the energy is absorbed in the form of heat.
A candle burning and Plaster & water combining and becoming warm : In both the process, the energy is released in the form of heat.
Salt being added to water, with no change in temperature : In this process, neither energy released nor absorbed.
