Consider this system at equilibrium. A(aq)↽−−⇀B(aq)ΔH=+350 kJ/mol What can be said about Q and K immediately after an increase i

n temperature? Q < K because Q decreased. Q < K because K increased. Q > K because Q increased. Q > K because K decreased. Q = K because neither changed. How will the system respond to a temperature increase?

Answer:

A.) Q < K because Q decreased

B. shift right

Explanation:

Reactant-------->Products

K = Product/Reactant

An endothermic reffers to any reaction which absorbs energy from its surroundings, usually in the form of heat.

ΔH. In endothermic reactions, K increases when Temperature increases.

The given reaction is an endothermic reaction, and in an endothermic reaction, when there is increase in temperature, the product side is more favored. The system will shifts to the right side of the reaction. Q < K then K is constant and Q is decreased.then Q < K because Q decreased

The system respond to a temperature increase by shifting to the right

The beakers in the picture above are labeled according to the ionic solutions they contain. What metal or metals could replace c
tangare [24]

Explanation:

When a metal replaces another metal in solution, we say such a reaction has undergone a single displacement reaction.

In such a reaction, metal higher up in the activity series replaces another one due to their position.

To known the metal or metals that will replace the given copper, we need to reference the activity series of metals.

Every metal higher than copper in the series will displace copper from the solution.

So, there metals are: potassium, sodium, lithium, barium, strontium etc.

¿Cómo se escribe la fórmula molecular (orden de los iones)?
cluponka [151]

Answer:

A la izquierda el catión y a la derecha el anión.

Explanation:

¡Hola!

En este caso, y basado en las normas IUPAC para la escritura de las fórmulas moleculares, es necesario primero escribir el catión a la izquerda, seguido del anión a la derecha, tal y como se muestra en los siguientes ejemplos, recordando que el catión es el ion cargado positivamente y el anión, negativamente:

K^+Cl^-\\\\Ag_2^+(SO_4)^{2-}

Los cuales son cloruro de potasio y sulfato de plata respectivamente. También es necesario tener en cuenta que los metales tienden a ser cationes por su capacidad de perder electrones, mientras que los no metales a ganarlos y por ende resultar como aniones.

¡Un gusto ayudarte!

Use Boyle’s law to complete the following:
mixas84 [53]

Answer:

The answer to your question is: 0.25 l

Explanation:

Data

P1 = 1 atm

V1 = 0.5 l

P2 =2 atm

V2 = ?

T = constant

Formula

          V1P1 = V2P2

Clear V2 from the formula

            V2 = V1P1/P2

Substitution

            V2 = (0.5)(1)/2  substitution

                  = 0.25 l       result
