Answer:
B.bonds are broken and new bonds are formed
Wood, Water, and Neon Gas, because the wood is more of a solid its particles are tightly arranged and water next because it takes the shape of the container it is in and then the neon gas because with a gas the particles are not at all arranged
After ionization, sodium gains a net positive charge cuz sodium loses its 1 valence electron to gain the nearest stable octet which is neon{Ne}. Hope it helps

Ovary
Explanation:
ovaries produce the most estrogen in females.
Answer : The concentration of A after 80 min is, 0.100 M
Explanation :
Half-life = 20 min
First we have to calculate the rate constant, we use the formula :
Expression for rate law for first order kinetics is given by:
where,
k = rate constant =
t = time passed by the sample = 80 min
a = initial amount of the reactant = 1.6 M
a - x = amount left after decay process = ?
Now put all the given values in above equation, we get
Therefore, the concentration of A after 80 min is, 0.100 M
