Yesterday we combined Hydrochloric Acid HCl with Sodium Hydroxide NaOH in a violent reaction that resulted in water H2O and common table salt NaCl. How many grams of hydrochloric acid should we use so we have exactly enough to react with 40g of sodium hydroxide? You'll need to write a chemical reaction, balance it, and then perform your calculation. also how many grams of salt NaCl will be produced and how many grams of water H2O be produced?

The change of state from liquid to gas is called

Answers

When liquid surface particles transition into gas phase, evaporation occurs. The process of change of state from liquid to gas is called as evaporation.

What is evaporation ?

The process of evaporation turns liquid water into gaseous water (water vapor). Evaporation is how water gets from the surface of the Earth to the atmosphere. Heat energy causes the bonds holding the water molecules together to fall apart, which causes evaporation.

When liquid surface particles transition into gas phase, evaporation occurs. Only the liquid particles near the surface have enough energy to separate from the remainder of the liquid and exit into a gaseous phase, making it a surface phenomenon.

The water cycle includes evaporation, which is a crucial step. The evaporation process is driven by solar energy, or heat from the sun. It absorbs moisture from both the largest oceans and lakes as well as garden soil.

Thus, The change of state from liquid to gas is called as evaporation.

The change of state from liquid to gas is called evaporation because solid to liquid is called melting and liquid to solid is called freezing and solid to gas is called sublimation and gas to solid is called deposition. So liquid to gas is called evaporation......hope it helped :)

The water in a 150-mL flask is poured into a beaker that contains 600 mL of ethyl alcohol. Which substance is the solvent in this mixture?

Answers

Answer:

Ethyl alcohol is a solvent on the mixture.

Explanation:

Solution: It is a mixture of liquid in which solute (minor component) is distributed uniformly in a solvent (major component).

In a solution, mass of solute is always less than the mass of solvent.

Mass of water = 150 mL

Mass of ethyl alcohol = 600 mL

Mass of water < Mass of ethyl alcohol

Ethyl alcohol is a solvent on the mixture.
The solvent in the mixture is the ethyl alcohol assuming that the ethyl alcohol is not very dilute. The amount of the solvent must be greater than the amount of the solute. If the ethyl alcohol is dilute such that the resulting solution will have more water than pure ethyl alcohol, the solvent is water and the solute is ethyl alcohol.

What can the arrow in a chemical reaction be translated to mean?

Answers

When a chemical equation is written out, there will be an arrow to represent the chemical reaction occurring. In the equation 6H20+6CO2-->6C12H6O+6O2, the part before the arrow is what you start out with. Next comes the arrow, or the reaction. After the reaction, you have the end product.

Answer:

The arrow means "yield" or "react to form".

Explanation: The arrow means "yield" or "react to form".
