Answer: 14.62 ml
Explanation:
Molarity is defined as the number of moles of solute dissolved per liter of the solution.
where,
n= moles of solute
= volume of solution in ml = 250 ml
Now put all the given values in the formula of molarity, we get
To calculate the volume of base, we use the equation given by neutralization reaction:
where,
are the n-factor, molarity and volume of acid which is
are the n-factor, molarity and volume of base which is NaOH.
We are given:
Putting values in above equation, we get:
Thus the volume of NaOH solution the student will need to add to reach the final equivalence point is 14.62 ml
Flexible connections are used because bridges sway. If there were steel or non flexible connections, the road would crumble. Another reason is steel would expand or contract in the heat or cold. If the steel expanded or contracted, then the road would be weak. And since the people on the road don't want it to crumble, the architect put flexible connections instead of hard ones.
Answer:
Its a 1:1:1:1 molar ratio.
Explanation:
Element/Polyatomic Ion # on reactants side # on products side
Ag 1 1
NO3 1 1
Na 1 1
Cl 1 1
A material is a mixture if it is not pure
