I’m pretty sure the second blank is solid to a liquid and the third blank is melting point
Answer: The charges on cation and anion balances each other.
Explanation:
For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.
Thus 
combines with two 
ions to give neutral 
Answer:
Explanation:
this graph show the decrease in velocity with time
at time t=0 velocity is 40 m/sec
at time t=12sec velocity is decreases from 40 to 10 m/s
so the acceleration of the object at time=12 sec is
a=v/t
a=Δv/t
Δv=v1-v2=40-10=30 m/s
a=30/12=2.5 m/s^2
A scientific theory is something that can not be proven through experimentation, hope this helps
