Answer:
A. 2H₂O₂ → 2H₂O + O₂
Explanation:
- 2. H₂O₂ + OI⁻ → H₂O + O₂ + I⁻
If we <u>make a net sum of both reactions</u>, we're left with:
- H₂O₂ + I⁻ + H₂O₂ + OI⁻ → H₂O + OI⁻ + H₂O + O₂ + I⁻
Grouping species:
- 2H₂O₂ + OI⁻ + I⁻ → 2H₂O + OI⁻ + O₂ + I⁻
There is OI⁻ at both sides, so it is eliminated -same goes for the catalyst, I⁻-.
Thus the answer is option A.
Answer: The moles of gas present in the cylinder is 0.34 moles.
Explanation:
Given: 
= 2.7 atm, 
= 3.1 L, 
= 300 K
= ?, 
= 9.4 L, 
= 610 K
Formula used to calculate the final temperature is as follows.
Substitute the values into above formula as follows.
Now, moles present upon heating the cylinder are as follows.
Thus, we can conclude that moles of gas present in the cylinder is 0.34 moles.
The general rule followed is that if electronegativity difference is greater than 2, then it is considered an ionic bond. An ionic bond is a type of bond characterizing a transfer of electrons within a bond. Common examples are salts which adds that ionic bonds are common between a metal and a nonmetal. Therefore, the best answer from above is letter B.
Data validation → editing data → entry data → tabulation
This enables better integration, consumption and analysis of larger datasets using advanced business intelligence with analytics solutions.
<h3>What is data preparation ?</h3>
Data collection, combination, structure, and organisation are all steps in the process of preparing data for use in business intelligence (BI), analytics, and data visualisation applications.
- Data prep is a common colloquial term for data preparation. It is also referred to as "data wrangling," while other professionals use that phrase more specifically to mean "cleaning, structuring, and transforming data." This usage distinguishes data wrangling from the data pretreatment stage.
