DanielleElmas [232]

Answer:

B. particles in an object move faster

Explanation:

At higher temperatures, particles in an object moves faster.

Temperature is the degree of hotness or coldness of a body.

  • At higher temperature, the substance is very hot.
  • Temperature is related to the heat energy content of a body
  • As the temperature increases, the average kinetic energy of the particles of system increases more and more.
  • This is in compliance with the kinetic molecular theory of matter.
  • Therefore, at higher temperatures, particles in an object move faster.

For the chemical reaction 2HBr(aq)+Ba(OH)2(aq)⟶2H2O(l)+BaBr2(aq) write the net ionic equation, including the phases.
Crazy boy [7]

Answer:

2H⁺(aq) + 2OH⁻(aq)  --> 2H2O(l)

Explanation:

2HBr(aq)+Ba(OH)2(aq)⟶2H2O(l)+BaBr2(aq)

We break the compounds into ions. Only compounds in the aqueous form can be turned into ions.

The ionic equation is given as;

2H⁺(aq)  +  2Br⁻(aq)  + Ba²⁺(aq) + 2OH⁻(aq)   --> 2H2O(l)  +  Ba²⁺(aq)  + 2Br⁻(aq)

Upon eliminating the spectator ions; The net equation is given as;

2H⁺(aq) + 2OH⁻(aq)  --> 2H2O(l)
