Given a 0.200 M solution of anserine at its isoelectric point and ready access to 0.100 M HCl, 0.100 M NaOH and distilled water,
vekshin1

Solution :

Given :

Amount of anserine solution = 0.200 M

pH value is = 7.20

Preparation of 0.04 M solution of anserine from the 0.2 M solution.

0.2 M x x = 0.04 M x 1000 ml

x = 200 ml

So the 200 ml of 0.2 M anserine solution is required to prepare0.04 M of anserine.

0.1 M x x = 0.04 x 1000 ml

x = 400 ml

Therefore, 400 ml of HCl is needed.

Think about the decomposition reaction of ozone.
____ [38]

Answer:

3441.6 grams.

Explanation:

2 O₃ → 3 O₂

First we <u>convert 71.7 moles of ozone (O₃) into moles of oxygen gas (O₂)</u>, using the <em>stoichiometric coefficients</em> of the reation:

71.7 mol O₃ * \frac{3molO_2}{2molO_3} = 107.55 mol O₂

Then we <u>convert 107.55 moles of O₂ into grams</u>, using the <em>molar mass of O₂</em>:

107.55 mol * 32 g/mol = 3441.6 g

grigory [225]

Answer:

Pinelands

Explanation:

Pines and many other plants that grow in this habitat thrive in open sunny areas. Periodic fires burn through the pines, killing back hammock species that would otherwise take over, by casting shade with their dense canopies. Within 15 to 25 years a fire-free, shade intolerant pine fores would be replaced by subtropical hardwoods. In the event of a fire, however, these pineland plants do well. They have evolved with several adaptations for survival. The pineland habitat is capable of returning very quickly after a fire has passed.
