Given :
Number of molecules of hydrogen peroxide, N = 4.5 × 10²².
To Find :
The mass of given molecules of hydrogen peroxide.
Solution :
We know, 1 mole of every compound contains Nₐ = 6.022 × 10²³ molecules.
So, number of moles of hydrogen peroxide is :
Now, mass of hydrogen peroxide is given as :
m = n × M.M
m = 0.0747 × 34 grams
m = 2.54 grams
Hence, this is the required solution.
Answer:
D.) H-O
Explanation:
Polarity is determined based on the difference in electronegativity of the atoms. The greater the difference, the more polar the bond. The general trend is that the atoms in the top-right corner of the periodic table are the most electronegative.
A.) is incorrect because H-H has no electronegativity difference, making it nonpolar.
B.) and C.) are incorrect because their electronegativity differences are not the greatest.
D.) is correct because the electronegativity difference between the H and O is the greatest.
Answer:
A.
Explanation:
The paper clip allows elictricity to pass, unlike the eraser or paper
Answer:
an uneven charge between the oxygen molecule and 2 hydrogen molecules
Explanation:
Answer:
Neutral solution, pH of 7.
Explanation:
Red cabbage is a natural indicator which gives red color when an acid is added, green color when a base is added and <u>it gives blue color when a neutral solution is added. </u>
<u>Given that when some red cabbage indicator is added to a solution , it turns blue which means that the solution is a neutral solution. Neutral solution have a pH of 7.</u>
