Because it have positive 2 which b is the answer
Answer : The complete chemical equation is,
Explanation :
As we know that, in a chemical equation the reacting species present on left side and the product formed present on right side and a right arrow inserted between the reactants and product that show a chemical reaction taking place.
In the chemical reaction, the phases of the substances are also included and subscripts and superscripts are also used for the numbers.
For the given chemical reaction, the balanced chemical equation including the phases, is given by:
Answer: Option (b) is the correct answer.
Explanation:
It is known that,
pH + pOH = 14
So, pOH = 14 - pH
As the given pH is 9.3. Hence, pOH for the given solution will be calculated as follows.
pOH = 14 - 9.3
= 4.7
Therefore, pOH of the given solution is 4.7.
Answer: 1: The density of krypton at STP is 3.74 kg/m3 , or 0.00374 g/cm3 at STP of 0oC (273.15 K) and 1 atm

<h2>Answer with Explanation </h2>
Chromatography is utilized to isolate blends of substances into their segments. All types of chromatography chip away at a similar guideline. They all have a stationary stage (a strong, or a fluid bolstered on a strong) and a portable stage (a fluid or a gas). A paper chromatogram can likewise be utilized to recognize substances by contrasting them and known substances. Two substances are probably going to be the equivalent in the event that:
- they deliver a similar number of spots and these match in shading.
The spots venture to every part of a similar separation up the paper (have a similar R f esteem). Rƒ esteem, solutes, and solvents. The maintenance factor (Rƒ) might be characterized as the proportion of the separation ventured out by the solute to the separation gone by the dissolvable. It is utilized in chromatography to measure the measure of the hindrance of an example in a stationary stage in respect to a portable stage.
