A greater volume of acid will be needed to neutralize the sodium hydroxide thereby making the calculated concentration of acid for the second trial to decrease.
Titration is usually a way of determining the concentration of an unknown solution by accurately measuring the volume of a known solution that reacts completely with the unknown solution.
The point when reaction is completed is indicated by the end point of the reaction. If more base (sodium hydroxide) is added to the flask, then more volume of acid will be needed to neutralize it thereby making the calculated concentration of acid for the second trial to decrease.

<span>Satellites are either natural or man-made.
Neptune I also commonly knoiwn as Triton is the coldest known astonomical body in the solar sytem. Triton is planet Neptune's largest satellite and is the seventh largest moon in the Solar System. The said satellite is a liitle smaller than the Earth's Moon. This moon was discovered by William Lassell, a British astronomer, in the year 1846 on the 10th day of October. It was 17 days after Neptune was discovered by Johann Gotfried Galle and Heinrich Louis d' Arrest. Triton has a complex history . It was beleived to have a young surface compared to the solar system's age.</span>
- The person that was right about the chemical change is Elsa
- Chemical changes can be regarded as one that takes place when chemical reactions occur and there is formation of new product such as chemical elements or compounds .
- Physical change are one that doesn't result to formation of new chemical substances .
- When someone eat because digestion occur due to breaking down of the food by enzymes into the small molecules the and as result of this new product is formed such as urine , energy and others
<em />
<em>Therefore, Elsa is right.</em>

Although there exists a dipole moment in the molecule, I guess its nonpolar because the dipole is very small as the electronegativity difference between the Br and Cl is very low and so it can be neglected.
CH3NH2 can only have as many hydrogen bonds as hydrogen bonding sites in the molecule. CH3NH2 has two N−H bonds and a lone pair of electrons on the nitrogen atom. Therefore, CH3NH2 can form three hydrogen bonds with water.
