ANSWER

ANSWER: +1

EXPLANATION

What is the change in oxidation number of bromine in the following re-dox reaction Cl 2 +2HBr 2HCl+Br 2 A -2;0 B) -1;0 C) 0: -1 D) 0;-2

for Cl 2 +2HBr 2HCl+Br 2 , the Cl in Cl2 is reduced from "0" to

"-1" and the Br in HBr is oxidized from "-1" to "0"

So the change in oxidation number is +1

Answer: 15768 seconds

Explanation:            (50 years) x (365 da/yr) x (86,400 sec/da)

        =      (50 x 365 x 86,400)  seconds

        =        1.5768 x 10⁹ seconds

Answer:The number of BH+ Molecules will increase , and the number of water molecules will decrease

Explanation:

The number of OH- ions will increase, and the number of BH molecules will decrease.

Option (3) is correct.

In the given base solution equation, B + H₂O = BH⁺ + OH⁻, when the strength of the base is increased, more B molecules will react with water to form BH⁺ and OH⁻ ions. This happens because a stronger base donates more OH⁻ ions into the solution, increasing its concentration.

As the base becomes stronger, more B molecules will participate in the reaction, forming fewer BH⁺ molecules since they are being converted to BH⁺ ions. Simultaneously, the increased concentration of OH⁻ ions means that the number of OH⁻ ions in the solution will increase.

Overall, the change in the number of particles can be summarized as follows:

The number of BH molecules will decrease.

The number of OH⁻ ions will increase.

This change reflects the increase in the concentration of OH⁻ ions, which is a characteristic of a stronger base solution.

They tend to be small in size and there are many of them. The primary consumers are herbivores (vegetarians), Because of this inefficiency, there is only enough food for a few top level consumers, but there is lots of food for herbivores lower down on the food chain. There are fewer consumers than producers.

Answer:

The original marshmallow was named for the inclusion of marshmallow root in the recipe. The roots and leaves of the marshmallow plant contain mucilage, a slimy-textured demulcent best known for its use as a homeopathic cough suppressant. Marshmallow root is considered to be soothing and mildly antimicrobial. It has long been used as an herbal treatment for minor digestive issues and skin irritations, although its use in the creation of its namesake confection has long since fallen by the wayside.

So basically salt makes it strecthy! Please mark brainliest!!

Baking soda is a salt of sodium and bicarbonate ions. In a soda test, the breath will raise the temperature as it contains water vapor and decomposes the soda.

The baking soda is also called sodium bicarbonate, and the test uses sodium bicarbonate as a reactant. It is also a leavening agent that is used in the preparation of food.

Breath contains some amount of water vapor that alters the test by diluting it and resulting in the clouding of the test. The water vapor decomposes the baking soda and alters the test results.

Therefore, breath contains water vapor.

Answer:

Nitric acid decomposes sodium cyanide and sodium halide. else, they precipitate in test and misguide the result. Therefore, dilute nitric acid is added before testing halogens to expel all the gases if evolved.

If excess solvent is added, discard the entire solution and begin the process of preparing the solution afresh.

It is common to prepare solutions using a standard volumetric flask. In this method, the required amount of solid or liquid is added to the volumetric flask and made up to mark with solvent.

Sometimes, it is possible to mistakenly exceed the mark as the solvent is added. In such cases, you must discard the entire solution and begin the process of preparing the solution afresh.

Considering the definition of dynamic equilibrium, the correct answer is second option: Nitrogen and hydrogen combine at the same rate that ammonia breaks down.

Chemical equilibrium is a state of a reaction in which no changes are observed as time passes, even though the reaction continues. That is, the chemical equilibrium is established when there are two opposite reactions that take place simultaneously at the same speed.

So, dynamic equilibrium is a chemical equilibrium, which occurs when two reversible processes happen at the same speed in both directions. In this way, the concentrations of the reactants and products remain constant over time.

In summary, the correct answer is second option: Nitrogen and hydrogen combine at the same rate that ammonia breaks down.
