Answer:
Yes.
Explanation:
Yes, I agree with Bryce and his lab partner because titration is completed when the solution changes its colour. Add chemical from the burette until the solution change its colour so then calculate the amount of chemical is used from the burette and the time at which the titration is completed. Always be careful for calculating the titration in order to get accurate data of the solution.
The phase change is called deposition, when a gas transforms into a solid without passing through the liquid phase.
Answer:
0.01235 moles
Explanation:
<em>Given data:</em>
volume = 47.5 ml = 0.0475 L
concentration = 0.260 M
<em>To find:</em>
number of moles: ?
<em>Formula:</em>
No of moles = concentration x volume (in litres)
M is equal to moles per liter, so if you multiply the volume in liters times the value of M, the result will tell you the number of moles.
<em>Solution: </em>
no. of moles = 0.260 M x 0.0475 L
= 0.01235 moles
Answer:
Hydrogen
1. has one electron in the outermost shell
2.It is less electronegative
Oxygen
3.It requires two electrons to complete its outer shell
4.It is more electronegative
Explanation:
Each hyrogen of two will share its electron with oxygen.Oxygen requires two electrons to complete its outer shell so it will share with two hydrogen. Covalent bonds formed will be polar as oxygen will attract electrons towards it due to high electronegativity. This happens in water molecule
