In complete sentences, describe the behavior of a substance in each state of matter if placed in a closed container

Chemistry

Bezzdna [24]3 years ago
8 0

In a closed container the three states of matter would be solid, liquid and gas

Solid- The solid exists as a rigid solid and has fixed shape and volume. Strong inter molecular and intramuscular forces inhibit the solid from losing its shape and occupying the volume of container.

Liquid- It takes the shape of the container  but not the volume of the container. This means the kinetic energy is not large enough for the liquid to cover all the space inside the container.

Gas- The gas expands to take both the shape and volume of the container. This would explain why a balloon inflates when you blow air into it.

A 52.0-mL volume of 0.35 M CH3COOH (Ka=1.8×10−5) is titrated with 0.40 M NaOH. Calculate the pH after the addition of 23.0 mL of
Georgia [21]

NaOH reacts with CH3COOH in 1:1 molar ratio to produce CH3COONa 

NaOH + CH3COOH → CH3COONa + H2O 

Mol CH3COOH in 52.0mL of 0.35M solution = 52.0/1000*0.35 = 0.0182 mol CH3COOH 

Mol NaOH in 19.0mL of 0.40M solution = 19.0/1000*0.40 = 0.0076 mol NaOH 

These will react to produce 0.0076 mol CH3COONa and there will be 0.0182 - 0.0076 = 0.0106 mol CH3COOH remaining in solution unreacted . Total volume of solution = 52.0+19.0 = 71mL or 0.071L 

Molarity of CH3COOH = 0.0106/0.071 = 0.1493M 

CH3COONa = 0.0076 / 0.071 = 0.1070M 

pKa acetic acid = - log Ka = -log 1.8*10^-5 = 4.74. 

pH using Henderson - Hasselbalch equation: 

pH = pKa + log ([salt]/[acid]) 

pH = 4.74 + log ( 0.1070/0.1493) 

pH = 4.74 + log 0.717 

pH = 4.74 + (-0.14) 

pH = 4.60.

PLEASE HELP! sketch the structure of the nitrogen-containing product that is formed when ethylamine reacts with water​
Aleksandr [31]

First of all the ethylamine is base so will be react with water to take the proton from the water (H⁺) , because water is amphoteric will react with bases as acid and acids as a base, so the water in this case will react as an acid and will gives the proton to the base.

In the picture you may see the chemical equation and the structure of the products.

You have 180 g of radium that takes up 36 cm ^ 3 of space if you were to cut it in half and have only 90 g
Leno4ka [110]

If you were to cut the radium  in half and have only 90 g, it will take up 18 cm³.

<h3>What is density?</h3>

The density of an object is the ratio of mass to volume of object.

Density = mass/volume

volume = mass/density

at a constant density, the volume of an object is proportional to its mass.

From the question, you have 180 g of radium that takes up 36 cm ^ 3 of space if you were to cut it in half and have only 90 g, the new mass will take the following volume.

180 g = 36 cm³

90 g =  ?

= (90 x 36) / 180

= 18 cm³

Thus, if you were to cut the radium  in half and have only 90 g, it will take up 18 cm³.

Given the reaction for the nickel-cadmium battery: 2NiOOH + Cd +2H2O -&gt; 2Ni(OH)2 + Cd(OH)2 What species is oxidized during th
jok3333 [9.3K]

Answer:

Cd is oxidized during the discharge of the battery

Explanation:

Based on the reaction:

2 NiOOH + Cd + 2H₂O → 2Ni(OH)₂ + Cd(OH)₂

And knowing Oxygen and hydrogen never change its charge, we must to find oxidation state of Ni and Cd before and after the reaction:

<em>Ni:</em>

In NiOOH: 2 O = -2*2 = -4 + 1H = +1, = -4 + 1 = -3. And as the molecule is neutral, Ni is 3+

In Ni(OH)₂: OH = -1. As there are 2 OH = -2. That means Ni is +2

The Ni is gaining one electron, that means is been reduced

<em>Cd:</em>

Cd before reaction is as pure solid with oxidation state = 0

Cd after the reaction is as Cd(OH)₂: 2 OH = -2. That means Cd is +2

The Cd is loosing 2 electrons, that means is the species that is oxidized.
