The steps usually involves adding the known solution (the titrant) to a known quantity of the unknown solution (the analyte) until the reaction is complete which can be understood in detail as below with the help of through out process of titration.
<h3 /><h3>What is Titration ?</h3>
A titration is a technique used to work out the concentration of an unknown solution based on its chemical reaction with a solution of known concentration.
Steps in order to determine the concenteration of base solution ;
(Acid-Base Titration)
- Choose the titrant.
- Choose the titrate.
- Select the normality of the titrate.
- Choose the volume of the liquid to be pipetted out.
- Select the indicator.
- Start titration.
- End point is noted at the colour change of the solution.
- From the final reading the normality of titrant can be calculated by the equation:
N₁V₁=N₂V₂
- After finding the normality, the amount of given substance in the whole of the given solution can be calculated by the equation:
Mass = Equivalent weight x Normality \ Volume {1000}

#SPJ1
Answer: d. smaller.
Explanation:
Hybridization :
![N=\frac{1}{2}[V+N+A-C]](https://tex.z-dn.net/?f=N%3D%5Cfrac%7B1%7D%7B2%7D%5BV%2BN%2BA-C%5D)
N = number of electrons
where, V = number of valence electrons present in central atom i.e. oxygen = 6
N = number of monovalent atoms bonded to central atom=32
C = charge of cation = 0
A = charge of anion = 0
The number of electrons is 4 that means the hybridization will be 
and the electronic geometry of the molecule will be tetrahedral. The bond angle for tetrahedral geometry is 
But as there are two atoms around the central oxygen, the third and fourth position will be occupied by lone pair of electrons. The repulsion between lone and bond pair of electrons is more and hence the molecular geometry will be bent and the bond angle will be smaller than expected and is 
Answer:
P(H₂) = 0.8533 atm
Explanation:
n(CO) = 0.220 mole
n(H₂) = 0.350 mole
n(He) = 0.640 mole
_______________
∑ n = 1.210 moles
mole fraction => X(H₂) = 0.350/1.210 = 0.2892
Dalton's Law of Partial Pressures => P(H₂) = X(H₂)·P(ttl) = 0.2892(2.95 atm) = 0.8533 atm
The solar system consist of stars and sun
Hello !!
I think the answer will be is :
<h2>
B. Elements are different kinds of atoms.</h2><h2>
</h2>
Because when the atom changed it's means it's different types of the atom.
