The density of acetic acid is 1.05 g/mL. What is the volume of 327 g of acetic acid

Chemistry

Answer:

311.43\ \text{mL}

Explanation:

\rho = Density of acetic acid = 1.05\ \text{g/mL}

m = Mass of acetic acid = 327\ \text{g}

V = Volume

Density is given by

\rho=\dfrac{m}{V}\\\Rightarrow V=\dfrac{m}{\rho}\\\Rightarrow V=\dfrac{327}{1.05}\\\Rightarrow V=311.43\ \text{mL}

The volume of acetic acid is 311.43\ \text{mL}.

Use the picture of the heliocentric and geocentric models to answer the question below:
xxMikexx [17]

Answer:

Model 1 represents the old geocentric model of the solar system and Model 2 represents the newer heliocentric model of the solar system.

Explanation:

Model 1 has earth in the center, therefore it is geocentric. the geocentric model of the solar system is old. Nobody believes in it anymore because it is scientifically inaccurate.

Model 2 has the sun in the center, therefore it is heliocentric. This is the newer model of the solar system.

In an ionic compound, the size of the ions affects the internuclear distance (the distance between the centers of adjacent ions)
gregori [183]

Answer:

The correct answer will be " RbF > RbCl > RbBr > Rbl".

Explanation:

The size of the given ions will be:

<u>RbCl:</u>

⇒  689kJ/mol

<u>RbBr:</u>

⇒  660kJ/mol

<u>Rbl:</u>

⇒  630kJ/mol

<u>RbF:</u>

⇒  785kJ/mol

Now according to the size, the arrangement will be:

⇒  (785kJ/mol) > (689kJ/mol) > (660kJ/mol) >(630kJ/mol)

⇒  RbF > RbCl > RbBr > Rbl

The bond among all opposite charging ions seems to be strongest whenever the ions were indeed small.

identify the precipitate(s) of the reaction that occurs when a silver nitrate solution is mixed with a sodium chloride solution.
zlopas [31]

The precipitate of reaction that occurs when silver nitrate solution is mixed with sodium chloride solution is of silver chloride (AgCI).

The chemical equation for this precipitation reaction is as following:

AgNO3(aq) + NaCl(aq) --> AgCl(s) [precipitate]+NaNO3(aq)

  • Silver Chloride is a chemical compound which is poorly soluble in water because the chemical bond between Ag+ and Cl is very strong as the two ions are nearly the same size and have similar electronic densities.
  • If the chemical bond is strong, it is difficult for water molecules to break this bond to surround the individual ions, thus solubility will decrease.

Match the action to the effect on the equilibrium position for the reaction N2(g) + 3H2(g) ⇌ 2NH3(g). (3 points)
AleksandrR [38]

Answer:

1. Adding hydrogen gas, b. shift to the right
2. Adding a catalyst, c. No effect
3. Decreasing the pressure, a. shift to the left

Explanation:

Hydrogen gas can be rewritten as H2. Whenever you add something to an equilibrium expression, it will shift to whichever side does not have this. So, since the reactant side has 3 moles of H2, adding more H2 to the reaction will shift to the products side, since there is no H2 there.


Adding a catalyst has no effect on equilibrium reactions.

When decreasing the pressure, equilibrium will shift to the side with the greater number of moles of gas. In this case, there are 4 moles of gas on the left, and 2 on the right, so it would shift to the left.
