3 moles of NaOH reacts with 1 mole of phosphoric acid.

<h3>What is the moles ratio of the NaOH and Phosphoric acid reaction?</h3>

The moles ratio of the reaction between NaOH and Phosphoric acid is given by the equation of the reaction below:

$3\:NaOH + H_{3}PO_{4} \rightarrow Na_{3}PO_{4} + 3\:H_{2}O \\$

Based on the equation of the reaction, 3 moles of NaOH reacts with 1 mole of phosphoric acid.

How do I draw energy level diagrams?

finlep [7]

Energy levels inside an atom are the specific energies that electrons can have when energy occupies specific orbitals. Electrons can be excited to higher energy levels by absorbing energy from the surroundings, an equivalent light is emitted when an electron returns from a high energy state to a lower one. Representation of this diagrammatic is known as the energy level diagram.

(3) 1. HCl NaOH: In Part I: An aqueous solution of sodium hydroxide reacts with an aqueous solution of hydrochloric acid, yieldi

FinnZ [79.3K]

Answer:HCl(aq) + NaOH (aq) -> NaCl (aq) + H2O(l)

Explanation:

The reaction of HCl and NaOH is a neutralization reaction. When an acid and a base react salt and water is produced.

HCl(aq) + NaOH (aq) ----> NaCl (aq) + H2O(l)

Because the reactants and products are ionic compounds, they exist as ions in a solution.

H+(aq) + Cl-(aq) + Na+(aq) + OH-(aq) -------> Na+(aq) + Cl-(aq) + H2O(l)

The aim of a neutralization reaction is the formation of water. Na+(aq) + Cl-(aq) remain the same on both the reactants side and the products side, the net ionic reaction will be

H+(aq) + OH-(aq) -------> H2O(l)

Can someone help me please have a question im stuck on in my physical science class

9966 [12]

Hey there!
Usually, there's some sort of force, whether it be a wave or an earthquake.
A medium is what that force travels through.
Here's an example.
In water, the water waves would be the force, and the water would be the medium.
But not all matter needs a medium.
For example, we have light. If you've ever heard the speed of light being 300,000 meters/second on a vacuum, that means empty, open space. It's what's classified as an electromagnetic wave, and those actually don't need a medium.
Hope this helps!

Question 18The osmotic pressure exerted by a solution is equal to the molarity multiplied by the absolute temperature and the ga

alexandr1967 [171]

The given question is incomplete, the complete question is:

The osmotic pressure exerted by a solution is equal to the molarity multiplied by the absolute temperature and the gas constant R. Suppose the osmotic of a certain solution is measured to be 6.6 atm at an absolute temperature of 308. K.Write an equation that will let you calculate the molarity of this solution. Your equation should contain only symbols. Be sure you define each symbol other than R.

Answer:

The correct answer is 0.26 M.

Explanation:

The extra pressure, that is, presented upon the solution to inhibit the process of osmosis is termed as the osmotic pressure. The formula to use for the question is π = CRT.

In the given formula, C is the concentration, π is the osmotic pressure, T is the temperature, and R is the gas constant.

The values or R, T and π given in the question is 0.0821 atmLmol^-1K^-1, 308K and 6.6 atm.

By putting the values in the given equation we get:

6.6 atm = C * 0.0821 atmLmol^-1K^-1 * 308K

6.6 atm/25.3 Lmol^-1atm = C

C = 0.26 M

Hence, the molarity of the solution is 0.26M.
