3. strong ones have more h30 weak ones have more OH
4. strong ones have more OH weak ones have more H30
5. <span>One of the main differences between acids and bases is that acids have a pH that is less than 7 and bases have a pH that is greater than 7. When dissolved in water, acids are substances that will cause the concentration of hydrogen ions (H+) to increase. Bases, when dissolved in water, will instead cause the number of hydroxide ions (OH-) to increase.6.Idk </span>
Answer:
Formula weight of H₂O molecule is 18.02 amu.
Explanation:
Given data:
Formula weight of H₂O = ?
Atomic mass of H = 1.008 amu
Atomic mass of O = 16.00 amu
Solution:
Formula weight:
"It is the sum of all the atomic weight of atoms present in given formula"
Formula weight of H₂O = 2×1.008 amu + 1×16.00 amu
Formula weight of H₂O = 18.02 amu
Thus, formula weight of H₂O molecule is 18.02 amu.
When it’s warmer so when temperature encreases
The new concentrations of
and
are 0.25M and 19M
Calculation of number of moles of each component,
Molarity of
= number of moles/volume in lit = 0. 500 M
Number of moles = molarity of
× volume in lit = 0. 500 M× 0.025 L
Number of moles of
= 0.0125 mole
Molarity of
= number of moles/volume in lit = 0. 38 M
Number of moles = molarity of
× volume in lit = 0. 38 M× 0.025 L
Number of moles of
= 0.95 mole
Calculation of new concentration at volume 50 ml ( 0.05L)
Molarity of
= number of moles/volume in lit = 0.0125 mole/0.05L
Molarity of
= 0.25M
Molarity of
= number of moles/volume in lit = 0.95mole/0.05L
Molarity of
= 19 M

Answer:
<u>During Metaphase</u>
<u></u>
Explanation:
During Metaphase the cell chromosome align themselves in the middle of the cell.This occur due to a cellular process called "Tug of War".
The chromosome which have been replicated and joined at the central point called centromere are called sister chromatids
Prior to metaphase , Kinetochore type of protein are formed around the centromere. Long protein filament called kinetochore are extended from poles to other end of the cell attached to kinetochore.
Therse is important checkpoint in the middle of mitosis called<u> metaphase.</u>
At this point cell ensure that , it is ready to divide or not.
Once the cell ensure that everything is ready to divide. Only after then , yhe cell enters the fourth phase called <u>anaphase.</u>
