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.

Answer:
La energía de activación suele utilizarse para denominar la energía mínima necesaria para que se produzca una reacción química dada. Para que ocurra una reacción entre dos moléculas, estas deben colisionar en la orientación correcta y poseer una cantidad de energía mínima. A medida que las moléculas se aproximan, sus nubes de electrones se repelen. Para superar esto se requiere energía (energía de activación), que proviene de la energía térmica del sistema, es decir la suma de la energía traslacional, vibracional, y rotacional de cada molécula

Explanation:
If Earth’s temperatures increase, it would likely have these effects:
The East Coast of the United States will face an increased risk of hurricanes as warmer waters increase evaporation.
The polar region will experience melting ice caps, which will cause sea levels to rise.
Warmer water in the Great Lakes will cause heavier lake-effect snows.
In the Pacific Ocean, heating of the water will cause a change in convection currents.
Hot, dry conditions will increase the risk of wildfires in the forests of California.
In the Himalayas, animal and plant life will migrate to higher ground to live.
The coastal regions of Europe will be at greater risk of flooding because of rising sea levels.
Answer:
<em>the </em><em>answer </em><em>should</em><em> be</em><em> </em><em>square</em><em>,</em><em> because</em><em> </em><em>by </em><em>it's </em><em>area</em><em> </em><em>formula</em><em> </em><em>(</em><em>l²</em><em>)</em><em>we </em><em>can </em><em>tell </em><em>that </em><em>all </em><em>it's </em><em>sides </em><em>are</em><em> </em><em>equal.</em><em>b</em><em>u</em><em>t</em><em> </em><em>for </em><em>a </em><em>circle </em><em>it </em><em>just </em><em>has </em><em>a </em><em>circumference</em><em> </em><em>and </em><em>not </em><em>sides.</em><em>a</em><em> </em><em>rectangle</em><em> </em><em>on </em><em>the </em><em>other </em><em>hand</em><em> </em><em>has </em><em>only</em><em> </em><em>two </em><em>sides </em><em>equal.</em>
<em>but </em><em>I </em><em>also </em><em>think</em><em> </em><em>the </em><em>answer </em><em>could </em><em>be </em><em>cube </em><em>because</em><em> </em><em>all </em><em>it's </em><em>faces </em><em>are </em><em>equal</em><em>.</em>
