What is H2CO3

H2CO3 is carbonic acid and contains hydrogen and carbonate (2 hydrogen, 1 carbon and 3 oxygen).

A material used to decrease the rate of a reaction

A material used to decrease the rate of a reaction

Bronsted and lowry defined an acid as a substance that what protons in a reaction with a base

Bronsted and Lowry defined an acid as a substance that donates protons.

A solution has a pH of 3.4. What is the pOH of this solution

pH + pOH = 14

If the pH is 3.4, the pOH is 10.6

What is the formula for equilibrium constant

Keq= ([A]a[B]b/[C]c[D]d)

What happens to a reaction at equilibrium when more reactants are added to the system

The equilibrium would be disturbed and by Le Chetalier's Principle the system would react to restore equilibrium. It would do this by forming more products.

What is the effect of adding more water to the following equilibrium reaction

Equilibrium is pushed to the reactant side

Is 1pH more acid than 4pH

Yes, 1pH is more acid than 4pH

What causes the reaction rate to decrease as the reaction progresses

The concentration of the reactants decreases.

What happens to the potential energy of the molecules in a reaction

The potential energy of the molecules change during a reaction.

What does Le Chtelier's principle state

The Le Chtelier's principle states one thing. It is the dynamic equilibrium which is disturbed by changing the conditions and the position of equilibrium moves that makes a change.

What is keq for the reaction n2 3h2 2nh3 if the equilibrium concentrations are nh3 3 m n2 1 m and h2 2 m

Keq=1.33

What would happen if the equilibrium of a weak acid dissociation reaction were upset

The reaction would shift to balance the change

What is true of a Brnsted Lowry base

Bornsted Lowry base is an acid base reaction theory. The ideal came from Johannes Nicolaus Bronsted and Thomas Martin Lowry in 1923. The theory is that acid can lose or donate a proton.

How do you spell dielema

The correct spelling is "dilemma" (a predicament, a choice between two bad alternatives).

Is there energy in the reactants or products of endothermic reactions

There is energy in both, but there is more energy in the products than in the reactants.

Which of the following best describes a bronsted lowry acid base reaction

Acid + Base = Salt+Water (APEX)

How is Hess's law applied in calculation enthalpy

Hess's law, which states that if a chemical reaction can be expressed as the sum of two or more chemical reactions, the enthalpy change for the net reaction is equal to the sum of the enthalpy changes for the individual steps.

What equation would calculate the rate constant from initial concentration

The formula is:
k(T) = ([A][B])/r where:

- [A] and [B] are the concentrations of reactants
- r is the reaction rate

What of the following is a characteristic of a weak acid

It does not dissociate completely in water
