2HNO3 + Ca(OH)2 —> Ca(NO3)2 + 2H2O
Answer:
Newton's Second Law
Explanation:
Newton's second law of motion states that the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
(I'm going to assume this is an option, but please let me know if it's not!)
C.) There are FIVE states of matter in total
Answer:
The object will float on the surface of water if its density is less than the equal volume of water.
Explanation:
Density:
It is define as mass per unit volume.
d=m/v
it is mostly measure in g/mL
it is represented by ρ (rho)
The density of water is one gram per cubic centimeter. If the object is less denser than water it will float. If the density of object is greater than the density of water it will sink.
Other examples:
some rocks are more denser then water so they will sink in it.
density of oil is less than vinegar, so it will float on the surface of vinegar
The ionization reaction of the compound given are as follows:
1.) HI(aq)
HI(aq) -----> H+(aq) + I-(aq)
2.) LiOH(s)
LiOH(s) ------> Li+(aq) + OH-(aq)
Ionization<span> is the process by which an atom or a molecule acquires a negative or positive charge. Hope this helps. Have a nice day.</span>
