How do you think dry cleaning works?

<h2><em><u>During dry cleaning, the pump pulls solvent from the tank and sends it through the filters to remove any impurities. The filtered solvent then enters the cylinder, where it interacts with the fabrics and removes any soil. The solvent then travels back into the holding tank so it can begin the process again.</u></em></h2>

Answer and explanation:

A chemical change occurs when new substances or materials are produced to have different chemical properties from the reactants.

Some examples of this are paper burning, fruit rotting, and metal rusting.

Most solids
Daniel [21]
Most solids a) are dense and difficult to compress.

Most solids are closely compacted, their molecules are close together and vibrate. They don't move freely like gas or water molecules do.
They are difficult to be squeezed or flattened.

At 1173 K, Keq = 0.0108 for the following reaction: CaCO3(s) ⇄ CaO(s) + CO2(g) The reaction takes place in a 10.0 L vessel at 11
maxonik [38]

Answer:

The amount of calcium carbonate will increase.

Explanation:

K is the constant of a certain reaction when it is in equilibrium, while Q is the quotient of activities of products and reactants at any stage other than equilibrium of a reaction.

  • K>Q , reaction will move forward by making more product.
  • K<Q , reaction will move backward by making more reactant.

CaCO_3(s)\rightleftharpoons CaO(s) + CO_2(g)

Equilibrium constant of the reaction = K_{eq}=0.0108

Concentration of CaO=\frac{15.0 g}{56 g/mol\times 10.0L}=0.027 M

Concentration of CO_2=\frac{4.25 g}{44 g/mol\times 10.0L}=0.0096 M

Concentration of CaCO_3=\frac{15.0 g}{100 g/mol\times 10.0L}=0.015 M

Q=\frac{[CaO][CO_2]}{[CaCO_3]}

=\frac{0.027 mol/L\times 0.0096 mol/L}{0.015 mol/L}=0.0174

K_{eq}

This means that equilibrium will move in backward direction by which amount of calcium carbonate will increase.
