Answer: approximately 4.74pKa is when you take the -log10 of your Ka. Therefore, taking the -log10(1.8*10-5), we get a value of approximately 4.74 for our pKa for acetic acid.
Explanation: hope this helps
Based on the information given regarding the energy, the true statement is C. "The number of particles able to undergo a chemical reaction is less than the number that is not able to."
<h3>What is energy?</h3>
It should be noted that energy is the quantitative property that must be transferred to a body to perform work on the body.
In this case, the graph is shown with two inverted graph curves running close to each other, and one of the curves labeled T1 is slightly more spread out than the other labeled T2.
Here, T1 is the only sample with a particle able to react. Particle B is more likely to participate in the reaction than particle A and the number of particles able to undergo a chemical reaction is less than the number that is not able to.

Supersonic flight over land is typically forbidden to minimize disruption to people on the ground. This meant that until it was over open water, Concorde could not operate at its maximum Mach 2 capability.
<h3>What is Concorde?</h3>
- The Concorde is a tailless aircraft with a drooping nose, an oval delta wing, and a narrow fuselage that allows for seating for 92 to 128 passengers.
- It's improbable that Concorde will ever fly for an airline again in a commercial capacity. The economics of reactivating Concorde and incorporating it into the fleet of a contemporary airline would be challenging to justify, even if the technical and regulatory concerns could be handled.
- Supersonic flight over land is usually not allowed to minimize the impact on people on the ground. This meant that Concorde could not operate at its maximum Mach 2 speed until it was over an open body of water.

Experimental investigations<span> involve a process in which a "fair test" is designed and variables are actively manipulated, controlled, and measured in an effort to gather evidence to support or refute a </span>causal relationship<span>. Experimental investigations have a control group which does not receive any treatment. A classic example is "What is the effect of light color on plant growth?" In this experiment, the variable color of light is changed by the student. The student may compare red light to green light to natural light.
