Explanation:
Set up the ion formation equations, with ionization energy values for each electron in the valence layer, of the atoms of the chemical elements below: a) Na z=11 b) Ca z= 20 c) Sr z 38 d) Li z= 3 e) Cs z= 55 f) Be z= 43
When [HClO]= 0.01 M & [ClO]^- = 0.03M & NaOH = 0.003 mol and
Ka = 3.5 x 10^-8
and the equation is:
HClO + NaOH → Na^+ + ClO^-
initial 0.01 0.003 0.03 0.03
-0.003 - 0.003 +0.003 + 0.003
Final 0.007 0 0.033 0.033
We can get the PH from this formula:
PH = Pka + ㏒[conjugent base/weak acid]
PH = -㏒Ka + ㏒[Na]/[HClO]
= - ㏒ 3.5x10^-8 + ㏒(0.033/0.007)
= 8.13
The precaution to be taken while measuring the temperature of a liquid in a beaker is applying proper heat balance and taking all the required precautions.
- A beaker with an open top contains a sample of liquid. It exposes this sample to light.
- That liquid absorbs the light energy, turning it into heat energy. As a result, the liquid becomes warmer and evaporation is accelerated. As a result, there is less liquid in the beaker.
- Since it is well known that the surface temperature of a liquid, along with air movement above the liquid surface, is one of the dominant factors affecting evaporation, I want to measure the evaporation rate as a function of surface temperature.
- This can be done by applying a heat balance.

That both of them are warm....at a certain temputurature causing one to fell,cozy
Answer:
The most important information is: financial charges, annual fees, minimum payments and how the balance is calculated.
Explanation:
A Schumer Box is a table where the credit card companies disclose all the terms and conditions necessary to make a contract with them, as well as disclose all fees, charges, balances and elements that make up the credit card.
All information shown on a Schumer Box is important, but the most important is that which deals directly with the customer's money or balance. This information is: financial charges, annual fees, minimum payments and how the balance is calculated.
