The correct answer among the choice listed is the third option. The reaction between silver nitrate and potassium hydroxide will yield a precipitate which is the silver hydroxide product. This is because this substance is not very soluble in aqueous solution.
Answer:
Atoms, Different, compounds, atoms

Answer:
Explanation:
I assume the volume is 2.50 L. A volume of 25.0 L gives an impossible answer.
We have two conditions:
(1) Mass of glucose + mass of sucrose = 1.10 g
(2) Osmotic pressure of glucose + osmotic pressure of sucrose = 3.78 atm
Let g = mass of glucose
and s = mass of sucrose. Then
g/180.16 = moles of glucose, and
s/342.30 = moles of sucrose. Also,
g/(180.16×2.50) = g/450.4 = molar concentration of glucose. and
s/(342.30×2.50) = s/855.8 = molar concentration of sucrose.
1. Set up the osmotic pressure condition
Π = cRT, so
Now we can write the two simultaneous equations and solve for the masses.
2. Calculate the masses
We have 0.229 g of glucose and 0.871 g of sucrose.
3. Calculate the mass percent of sucrose
The particles are packed closely togetehr but not as tightly as in solids and the particles slide past one another. the particles ahev no regular arrangement, no fixed shape and it takes on the shape of the container it's in. it has a fixed volume and it can't be easily compressed.
Answer:
La densidad experimenta una disminución
Explanation:
Hola!
En este caso, debemos recordar que la adición de agua incrementa el volumen donde se encuentra un soluto disuelto, el cual posee una cantidad de materia constante. De este modo, sabiendo que la densidad es:
Al incrementar el denominador (volumen), la densidad experimenta una disminución, al estar en relación inversamente proporcional.
Muchos saludos!
