The change in oxidation number = +1

<h3>Further explanation</h3>

Reaction 1

Cl₂(aq) + H₂O(I) → H⁺(aq) + Cl⁻(aq) + HClO(aq)

Reaction 2

HClO(aq) + H₂O(I) → H₃O⁺(aq) + ClO⁻(aq)

The change in oxidation number of chlorine :

From Cl₂ to ClO⁻

oxidation number Cl₂=0

oxidation number Cl in ClO⁻

\tt Cl+(-2)=-1\\\\Cl=+1

So the change : +1

gavmur [86]

Answer:

2.4 hrs

Explanation:

The constant speed of the truck for 6 hrs can be calculated by: speed=distance/time. Speed =(876-228)/6=648/6=108m/s. So the decreased speed = (108-13)=95m/h. Now, speed =distance /time We get 95m/h = 228/t. t=228/95 hrs = 2.4 hrs PLEASE MARK ME THE BRAINLIEST!!

Based on the information given about capsules, which of the following types of molecules would you suspect comprises an S. pneum
Sergio039 [100]

"Polysaccharide carbohydrate" comprises an S. pneumoniae capsule.

<u>Option:</u> C

<u>Explanation:</u>

The lengthy sequences of carbohydrate molecules, primarily polymeric carbohydrates constructed of units of monosaccharides linked together through glycosidic connections, understood as Polysaccharides. This carbohydrate can respond to water by catalyzing amylase enzymes, which generate component sugars.

A major human pathogen is Streptococcus pneumoniae or pneumococcus. The virulence is primarily due to its polysaccharide envelope, which protects it from the recipient immune response, and this has led to comprehensive study of the shell.

Is a graph that starts at 25 and drops to 21, stays the same in temperature an endothermic reaction or an exothermic reaction?
ki77a [65]

Answer:

Explanation:

Endo and Exo thermic are defined by what changes take place in the environment of the reaction.

If the temperature goes up, the reaction is giving up heat. It is Exothermic.

If the temperature goes down, the reaction requires heat. It is Endothermic.

In this case, the temperature went down. The reaction is Endothermic.
