Answer:

Liquid, Gas and Plasma

Explanation:

➨Think about it like this if you put a material made out of these and flipped it over which one would have the most effect of change in shape?

▶Liquid molecules slide past each other meaning they are not held in place.

▶Gas molecules are "excited" they bounce around everywhere meaning they are not held in place.

▶Plasma has no fixed shape or volume so it cant be held in place!

▶Solid molecules have a fixed shape so they cannot move on their own.

<u>Hope I helped! Brainliest appreciated!</u>

Describe the interactions of the nervous and muscular system. please write a paragraph and do not plagiarize If you need to cite
Ksenya-84 [330]

The systems within the body associate with each other to keep the organism in a healthy state. Though every system of the body exhibits particular functions, they all are dependent and inter-associated with each other. The nervous system controls various systems of the body.  

The muscular system comprises distinct kinds of muscles that permit motion, produce heat to sustain a temperature of the body, does contraction of the heart, and move the food via the digestive tract. It comprises three kinds of muscles, that is, smooth, skeletal, and cardiac muscles.  

The muscular system coordinates with the nervous system and does various functions. The receptors found in muscles instruct the brain with the information regarding the movement and position of the body. The brain monitors the contraction of skeletal muscle. The nervous system monitors the speed at which food passes through the digestive tract.

G determine the concentration of an hbr solution if a 45.00 ml aliquot of the solution yields 0.6485 g agbr when added to a solu
Sunny_sXe [5.5K]

The molecular weight of silver bromide (AgBr) is 187.77 g/mole. The presence of the ions in solution can be shown as- AgBr (insoluble) ⇄Ag^{+} + Br^{-1}.

45.00 mL of the aliquot contains 0.6485 g of AgBr. Thus 1000 mL of the aliquot contains \frac{0.6485}{45}×1000 = 14.411 gm-mole. Thus the solubility product K_{sp}of AgBr = [Ag^{+}]×Br^{-}.

Or, 5.0×10^{-13} = S^{2} (the given value of solubility product of AgBr is 5.0×10^{-13} and the charge of the both ions are same).

Thus S = (5.00×10^{-13})^{1/2} = 7.071×10^{-7} g/mL.

Thus the concentration of Br^{-1} or HBr is 7.071×10^{-7} g/mL.
