Answer:
IOnic compound is NAcL cuz in the periodic table eft are metal and right are non metal makes it ionic (different)
Explanation:
Answer:
Shift in equilibrium position
Explanation:
The reddish-pink colour signalled the equivalence point. That is, pH=PKind. This was the point at which we have commonly the called the end point of the titration which has been carried out. As the solution was left to stand after this equivalence point was attained, the equilibrium position shifted again towards the acid side and the solution turned colourless once more. The equilibrium position indicated by the colour change depends on the H+ concentration of the solution.
Answer:
There are 0.1 moles of solute in 250 mL of 0.4 M solution.
Explanation:
First, recognize that the molar concentration tells you how many moles of the solute are present in one liter of solution. In a 0.4 M solution, there are 0.4 moles of solute in every liter of solution. You can determine the number of moles of solute in 250 mL of the solution using dimensional analysis.
250
ml . 1L/1000 L . 0.4mol / 1L
Units of liters and milliliters cancel, leaving you with a final answer in units of moles, at 0.1 mol.
