Answer: The size of the ion and the charge of the ion are the factors that affect solubility in water.
Explanation:
Lead lose electrons to become cations. Compounds with small ions tend to be less soluble than compounds with large ions. Large ions have higher solubility. This is because small ions are closely packed so it is difficult for water to break them apart.
Compounds with small ions seemingly have less solubility than those with large ions. The ions in the compound attract each other, and the water molecules attract the ions. Compounds would be soluble in water If the water molecules have a greater or higher attraction to the ions than ions have for each other.

Answer:
Pressure in the oil is 54.89 Mpa
Explanation:
Pressure is the ration of force applied to the perpendicular area. Pressure is uniform and perpendicular to surface.
Step1
Given:
Diameter of the piston is 30 mm.
Force exert is 38.8 kN.
Calculation:
Step2
Expression for pressure in the oil is expressed as follows:
Here, P is the pressure, A is the normal surface area and F is the exerted force on the piston.
Substitute the values in the above equation as follows:
pa.
Or,
P = 54.89 Mpa.
Thus, the pressure in the oil is 54.89 Mpa.
Answer:
you have to report to the federal aviation administration upon request
Explanation:
An unmanned aircraft can also be a drone it is an aircraft that does not have passengers or a human pilot.
Such an aircraft could be fully autonomous but most times they have a human pilot who controls it remotely.
Now you have to report this deviation to the federal aviation administration. This body is responsible for the enforcement of regulations that have to do with the manufacture, operation and maintenance of aircrafts. The body makes sure there is an efficient and safe system for a navigation and they also control air traffic.
Answer:
Explanation:
,K=1.35
Clearance is 8%.
Heat added=15 KJ
We know that compression ratio
r=13.5
We know that efficiency of otto cycle
W is the work out put and Q is the heat addition.
W=8.4 KJ
We know that Work =Mean effective pressure x swept volume.
Here swept volume
Noe by putting the values
Work =Mean effective pressure x swept volume.
