Answer:
The balanced reaction is given by,
⇒ 
Explanation:
The reaction is as given.
Lets count the number of each elements in the reaction.
<em>In reactant side, number of sodium atoms are 1 , lead are 1, nitrogen are 1 and oxygen are 4.</em>
<em>in product side, number of sodium atoms are 2 , lead are 1 , nitrogen are 2 and oxygen are 7.</em>
<em>So we need to balance sodium and oxygen atoms in the reaction.</em>
<em>There is deficient of sodium and oxygen atoms on reactant side</em>.
Thus, multiply (NaNO3) by 2.
<em>Thus, sodium atoms become 2 , nitrogen 2 and oxygen 6. Total 7 oxygen atoms.</em>
Thus, the balanced reaction is,

Answer:
A I did the exam and I saw A sorry if it is wrong dont have the best of memory
C. Lowering the temperature
At the lower temperature, particles have less kinetic energy, so they move slower.
Answer:
Liquid
Explanation:
Gas is too far away, solid is close but it is not in a random pattern
1/2 - 3/7 = 7/14 - 6/14 = 1/14
