<h2>Answer:</h2>
At 30 C, exactly 95 grams of this salt dissolved completely in 100 grams of water. According to the solubility chart, the salt is Sodium niatrate NaNo3
Every single metallic nitrate are inorganic salts of a given metal cation and the nitrate anion. The nitrate anion is a univalent (- 1 charge) poly atomic particle made out of a solitary nitrogen iota ionically bound to three oxygen molecules for an all out equation load of 62.05. Nitrate mixes are commonly solvent in water.
The heat is used to break the bonds between the ice molecules as they turn into a liquid phase. Since the average kinetic energy of the molecules does not change at the moment of melting, the temperature of the molecules does not change.
Answers with explanation
1)
Transmission
If all the light passes through a medium without any absorption then transmittance is 100%.
2)
Refraction
Refraction is the bending of a wave when it enters a medium where its speed is different and rays are again refracted when they leave that medium,
3)
Reflection
Reflected rays don't pass through the medium instead rays bounces off an object at an angle.
Answer:
10628.87 J
Explanation:
We are given that
Force applied =F=5592 N
Displacement=D=3.79 m
We have to find the work done in sliding the piano up the plank at a slow constant rate.
Work done=
The perpendicular component of force=
Work done =
Hence, the work done in sliding the piano up the plank at a slow constant rate=10628.87 J
