Based on what you learned about electronegativity, which would be the most electronegative acid?
A. HBr
B.HCl
C.HF
D.HI
Which pH results in the strongest acid?
A. 1
B.3
C.G
D.14
Your very rude. Learn some respect
well, the stronger the acid,the lower the pH.
*sips tea*
all he wants is answers, answers could help learn. you dont gotta be rude.
id help but idk ;(
The answers to the questions are as follows:
1. Charles's Law explains how the temperature and volume of a gas are related. As the temperature of a gas decreases, the volume of the gas will: B: decrease. This means that as the temperature decreases, the volume of the gas will also decrease.
To understand this relationship, you can think of gas molecules as being in constant motion. When the temperature is lowered, the average kinetic energy of the gas molecules decreases, causing them to move slower and collide with each other less frequently. As a result, the gas molecules become more compact, leading to a decrease in volume.
2. Having a higher pressure means that the particles of the gas collide with the sides of the container more often. A: the particles of the gas collide with the sides of the container more often. Pressure is the force exerted by gas molecules on the walls of the container. When gas particles collide with the container walls more frequently, it results in higher pressure.
3. Gay-Lussac's Law explains how the temperature of a gas is related to its pressure. If you cool down a container of gas, there will be fewer collisions with the side of the container, resulting in lower pressure. D: fewer, lower.
When you cool down a gas, the decrease in temperature causes the gas molecules to move slower and collide with each other less frequently. This leads to fewer collisions with the container walls, resulting in a decrease in pressure.
4. Electronegativity refers to the tendency of an atom to attract shared electrons towards itself in a chemical bond. In the given options, HF has the highest electronegativity.
The trend of electronegativity generally increases when moving from left to right across a period in the periodic table, and also increases when moving from the bottom to the top of a group. In this case, fluorine (F) is the most electronegative element among the options.
5. The pH scale is a measure of acidity or alkalinity of a solution. The lower the pH value, the stronger the acid. A pH of 1 would result in the strongest acid.
The pH scale ranges from 0 to 14, with a pH of 7 considered neutral. A pH value below 7 indicates acidity, and the lower the value, the stronger the acid. Therefore, option A with a pH of 1 results in the strongest acid.
