Answer:
Remain unchanged.
Explanation:
The total number of moles of liquid remain unchanged as the some moles of species B are added to the system because specie B that is added in the liquid phase is again restored after addition. If the specie B did not restored after addition to the liquid phase so the total number of moles increases in the liquid phase so that's why we can say that the liquid phase remain unchanged.
Answer:
The answer to your question is a balanced equation
Explanation:
Chemical formulas are extremely useful in chemistry and these formulas follow the law of proportions but not the law of conservation of matter.
Coefficients indicate that an equation is balanced if these numbers are in proportion but it is not the answer.
Balanced equation is a feature of the law of conservation of matter.
Subscripts are necessary for chemical reactions but they are not a feature of the law of conservation of matter.
Answer:
4
Explanation:
cause 1 mole of beryllium weighs 4gram
The symbols that will complete the equation for single displacement reaction is 2NaCl + Br2
Explanation
The balanced equation is as below
2NaBr + Cl2→ 2NaCl + Br2
A single displacement reaction is type of reaction in which element react with compound and take place of other element in that compound.
Mostly the more reactive element displaces the less reactive elements from its compound.
Chlorine (Cl2) is more reactive than bromine(Br2) therefore chlorine displaces bromine from its compound.
