Suppose a student titrates a 10.00-ml aliquot of saturated ca(oh)2 solution to the equivalence point with 16.08 ml of 0.0199 m h

Alborosie

Following chemical reaction is involved upon titration of Ca(OH)2 with HCl,
Ca(OH)2 + 2HCl ↔ CaCL2 + 2H2O

Above is an example of acid-base titration to generate salt and water. Here, H+ ions of acid (HCl) combines with OH- (ions) of base [Ca(OH)2] to generated H2O

Given,
concentration of HCl = 0.0199 M
Total volume of HCl consumed during titration = 16.08 mL = 16.08 X 10^(-3) L

∴, number of moles of H+ consumed = Molarity X Vol. of HCl (in L)
= 0.0199 X 16.08 X 10^(-3)
= 3.1999 X 10^-4 mol
Thus, total number of moles of [OH-] ions present initial = 3.1999 X 10-4 mol
So, initial conc. [OH-] ion = $\frac{number of moles of [OH-]}{volume of solution (L)}$ = $\frac{3.1999 X 10^(^-^4^)}{10 X 10^(^-^3^)}$ = 0.03199 M

if a dinosaur once lived in mexico, and i now live in arkansas, can i be drinking the same water the dinosaur did?

MrRissso [65]

Yes, especially if its from a lake, pond, or ocean since water moves around. Dinasours could have spit out or maybe dripped some water, so basically yes.

<h3>Answer:</h3>

Al- [Ne] 3s²3p¹

As- [Ar] 4s²3d¹⁰ 4p³

Explanation:

Electron configuration of an element shows the arrangement of electrons in the energy levels or orbitals in the atom.
Noble-gas configuration involves use of noble gases to write the configuration of other elements.
This is done by identifying the atomic number of the element and then identifying the noble gas that comes before that particular element on the periodic table.

For example:

Aluminium: The atomic number of Al is 13. The noble gas before Aluminium is Neon which has 10 electrons. Therefore the remaining 3 electrons fills up the 3s and 3p sub orbitals.

Thus, the noble-gas configuration of Al is [Ne] 3s²3p¹

2. Arsenic, Atomic number is 33

Noble gas before Arsenic is Ar,. Argon has 17 electrons, then the remaining electrons fills up the 4s, 3d and 4p sub-orbitals.
Thus, the noble-gas configuration of As is [Ar] 4s²3d¹⁰ 4p³
