You see, plants need energy to grow and grow and grow. They use energy from sunlight to make a simple sugar, glucose. Whenever the plant needs energy, it can chomp a little glucose off of the starch.

without energy it wont get energy/food so it will eventually die

What is the ph of 0.51 m ca(ch3coo)2 solution?

Sidana [21]

Answer : The pH of calcium acetate solution will be 9.38.

Explanation : When calcium acetate dissocates completely in solution to form Calcium(+2) ions and two acetate ions, this gives the acetate ion concentration as (2 X 0.51 M) = 1.02 M

Acetate ion then hydrolyzes as follows;

$C_{2}H_{3}O_{2}^{-} + HOH HC_{2}H_{2}O_{2} + OH^{-}$ :

Now, Kb will be = $[HC_{2}H_{2}O_{2}] [OH^{-}]$ / $[C_{2}H_{3}O_{2}^{-}]$

= Kw / Ka

= 1 x $10^{-14}$ / 1.8 x $10^{-5}$ = 5.6 × $10^{-10}$

$[OH^{-}]$ = 2.4 × $10^{-5}$

Now, we know , pOH = -log $[OH^{-}]$ = 4.62

So, the pH = 14 - pOH = 14 - 4.62 = 9.38

Has a definite, fixed volume. - Has a variable shape. - Particles are constantly moving and sliding by one another.

It would be a liquid, because a liquid takes the shape of the container it's in as a gas does, but unlike a gas it does not completely fill the container.
