Answer:
![Ka=\frac{[C_6H_5O^-][H^+]}{[C_6H_5OH]}](https://tex.z-dn.net/?f=Ka%3D%5Cfrac%7B%5BC_6H_5O%5E-%5D%5BH%5E%2B%5D%7D%7B%5BC_6H_5OH%5D%7D)
Explanation:
Hello,
In this case, weak acids are characterized by the fact they do not dissociate completely, it means they do not divide into the conjugated base and acid at all, a percent only, which is quantified via equilibrium. In such a way, the chemical equation representing such incomplete dissociation is said to be:
Thus, we can write the law of mass action, which consider the equilibrium concentrations of all the involved species, which is also known as the acid dissociation constant which accounts for the capacity the acid has to yield hydronium ions:
![K=Ka=\frac{[C_6H_5O^-][H^+]}{[C_6H_5OH]}](https://tex.z-dn.net/?f=K%3DKa%3D%5Cfrac%7B%5BC_6H_5O%5E-%5D%5BH%5E%2B%5D%7D%7B%5BC_6H_5OH%5D%7D)
Best regards.
The scientific models are used because they allow scientists to make predictions and make it easier for scientists to avoid using data. option A and C is correct.
<h3>What are scientific models?</h3>
The scientific models are those which is given by scientists to allow them to make prediction about anything particular on which they are working or making research for it some examples are plum pudding model for an atom and bohr's model of an atom etc.
The biggest advantage is that scientists do not have to check the given data which are written into books they can perform their experiment and can conclude the data by performing experiment.
Therefore, scientific models are used because they allow scientists to make predictions and make it easier for scientists to avoid using data. option A and C is correct.

<h3>
Answer:</h3>
15.0 meters
<h3>
Explanation:</h3>
- Kilometers are units used to measure length.
- Length is also measured using other units which include meters, centimeters, decimeter, millimeter, etc
- To convert one unit to another we use conversion factors.
In this case to know inter-conversion between units of measuring length, we consider the following;
Kilometer(km)
10
Hectometer(Hm)
10
Decameter(dam)
10
Meter (M)
10
Decimeter (dm)
10
Centimeter (cm)
10
Millimeter (mm)
Therefore, to convert km to meter we use the conversion factor (10×10×10) 1000 m/km.
Thus;
0.0150 km is equivalent to;
= 0.0150 km × 1000 m/Km
= 15.0 meters
Thus, 0.0150 km is equivalent to 15.0 meters.
Answer: d Positive particles in the nucleus are attracted to shared electrons, so the atoms stay close together.
