Atoms are electrically neutral because they have equal numbers of protons (positively charged) and electrons (negatively charged).
The balanced chemical reaction is expressed as:
M + F2 = MF2
To determine the moles of the element fluorine present in the product, we need to determine the moles of the product formed from the reaction and relate this value to the ratio of the elements in MF2. We do as follows:
moles MF2 produced = 0.600 mol M ( 1 mol MF2 / 1 mol M ) = 0.600 mol MF2
molar mass MF2 = 46.8 g MF2 / 0.6 mol MF2 = 78 g/mol
moles MF2 = 46.8 g ( 1 mol / 78 g ) = 0.6 mol
moles F = 0.6 mol MF2 ( 2 mol F / 1 mol MF2 ) = 1.2 moles F
I think that would be the third one
Answer: Option (a) is the correct answer.
Explanation:
A dissociation reaction is defined as the reaction in which a compound beaks down into two or more different parts.
For example, molecular formula of water is 
and when it dissociates then it given hydrogen ion and hydroxide ion.
Therefore, dissociation reaction for water is as follows.
Thus, we can conclude that out of the given options is the correct equation for the dissociation of water.
Answer:
Water is added to a concentrated solution of sodium thiosulfate to dilute it.
Explanation: Water is a universal solvent. It has the capability to dissolve many substances in it. When water is added to a solution, the concentrated solution can be diluted. Dilute solution means the presence of water in high amount and solute quantity is very low.
