Write a balanced net ionic equation for the reaction of aqueous solutions of baking soda (NaHCO3) and acetic acid.(A) HCO3–(aq)

IgorC [24]

Answer: The correct answer is Option C.

Explanation:

Net ionic equation of any reaction does not include any spectator ions.

Spectator ions are defined as the ions which does not get involved in a chemical equation. They are found on both the sides of the chemical reaction when it is present in ionic form.

The chemical equation for the reaction of sodium bicarbonate and acetic acid is given as:

$NaHCO_3(aq.)+CH_3COOH(aq.)\rightarrow CH_3COONa(aq.)+H_2O(l)+CO_2(g)$

Ionic form of the above equation follows:

$Na^+(aq.)+HCO_3^-(aq.)+CH_3COO^-(aq.)+H^+(aq.)\rightarrow CH_3COO^-(aq.)+Na^+(aq.)+H_2O(l)+CO_2(g)$

As, sodium and acetate ions are present on both the sides of the reaction. Thus, it will not be present in the net ionic equation and are spectator ions.

The net ionic equation for the above reaction follows:

$HCO_3^-(aq.)+H^+(aq.)\rightarrow CO_2(g)+H_2O(l)$

Hence, the correct answer is Option C.

Write a balanced equation for the double-replacement neutralization reaction described, using the smallest possible integer coef

g100num [7]

Answer: The balanced chemical equation is given below.

Explanation:

Double-displacement reaction is defined as the reaction in which exchange of ions takes place. The general equation representing this reaction follows:

$AB+CD\rightarrow CB+AD$

The balanced chemical equation for the reaction of barium hydroxide and perchloric acid follows:

$Ba(OH)_2(aq.)+2HClO_4(aq.)\rightarrow Ba(ClO_4)_2(aq.)+2H_2O(l)$

By Stoichiometry of the reaction:

1 mole of barium hydroxide reacts with 2 moles of perchloric acid to produce 1 mole of barium chlorate and 2 moles of water molecule.

Hence, the balanced chemical equation is given above.

What best explains the type of energy present in the wheels of a moving bus?

amm1812

The chemical energy, which is a type of kinetic energy explains the type of energy present in the wheels of a moving bus.

Explanation:

Kinetic Energy is the energy possessed by an object by virtue of its motion.

Kinetic Energy is present in every moving object. A moving bus, train,flying airplane, walking , running etc are some examples of Kinetic Energy.

Kinetic Energy is classified into two parts Rotational Kinetic Energy and vibrational Kinetic energy.

Kinetic energy depends on two things , the mass and the velocity of the object.

In the above example , in a moving bus,the wheels of the bus are also moving. So with motion, Kinetic energy gets formed.
