What is the quantum mechanical electron configuration of arsenic?
Answer:
After the 4s sublevel is filled with two electrons, ten electrons fill the 3d sublevel, which is slightly higher in energy than the 4s sublevel. After the 3d sublevel is filled, the remaining three electrons will be in orbitals in the 4p sublevel. Thus, the electron configuration for arsenic is [Ar] 4s(2 squared) 3d(10 squared) 4p(3 squared).
What mass of H2O is produced by the combustion of 1.00 mol of CH4?
CH4(g) + 202(g) → CO2(g) + 2H2O(e)
The mass of H2O is produced by the combustion of 1.00 mol of CH4 is 36.0 grams.
What do you mean by molar mass ?The term molar mass is defined as the mass of 1 mole of that particular substance and number of grams per mole of a compound.
The balance chemical equation is as follows:
CH4(g) + 202(g) → CO2(g) + 2H2O(e)
The mass of H2O = 36.0 g
Calculating the mass of H2O produced
mass of H2O = 1.00 mol CH4 × (2 mol H2O / 1 mol CH4) × (18.015 g H2O / 1 mol H2O)
mass H2O = 36.0 grams
Thus, The mass of H2O is produced by the combustion of 1.00 mol of CH4 is 36.0 grams.

Explanation:
Nitroglycerine, used to treat patients with angina, is prescribed for a patient by IV at a rate of 2.10 x 102 ug/min. The IV bag
contains 50. mg nitroglycerine/250 mL D5W. How many milliliters per hour should the patient receive?
Given the flow rate and the amount of nitroglycerine contained in the IV bag, the patient should receive 63 milliliters per hours.
Rate of prescribed dose by IV: [tex]2.10*10^2 ug/min = 210ug/min[/tex]
Available: [tex]50mg nitroglycerine = 50000ug[/tex]
Available Volume: [tex]150mL[/tex]
Hence, [tex]50000ug = 250ml[/tex]
and volume for [tex]210ug = x[/tex]
We cross multiply to find x
[tex]x = \frac{210ug * 250mL}{50000ug} \\\\x = 1.05mL[/tex]
Meaning that in a single minute, 1.05mL is been infused into the patient
Now, for an hour, ( 60 minutes ) the volume infused will be;
[tex]1min = 1.05mL[/tex]
[tex]60min = x[/tex]
We cross multiply to find x
[tex]x = \frac{1.05mL*60min}{1min}\\\\x = 63mL[/tex]
Therefore, given the flow rate and the amount of nitroglycerine contained in the IV bag, the patient should receive 63 milliliters per hours.

Explain why you would want to keep some, but not all, receipts as part of your financial records.
Answer:
Explanation:
Let's try and figure out the ones you don't keep.
Receipts from the dollar tree. You can't return what you bought and you only paid a dollar. It's not worth it.
Food receipts. You can't return it and unless you want to itemize what you spend / month and on what, they don't serve any purpose.
Now figure out which ones you would want to keep
1. Anything pertaining to medical perscriptions. I don't know how it works in the United States, but in Canada we are allowed to deduct only medications with a DIN number.
2 Anything that you would use for travelling that is not for pleasure (ie it is a business expense). So if you are a salesman and your territory is from A to B you would deduct meals, mileages, motels if you must stay away from home
3 In the states some tax receipts are deductible, so you might want to save those.

The accepted value of Ksp is 1.2×10−12 for Ag2CrO4. Calculate the percentage error if your experimentally determined value for Ksp was 1.5×10−10.
The percentage error in the experimental determination is 124%.
The experimentally determined value for Ksp = 1.5×10^−10
The accepted value of Ksp = 1.2 × 10^−12
The formula for percentage error is;
% error = absolute value of ( actual value - experimental value)/actual value × 100/1
% error = absolute value of (1.2 × 10^−12 - 1.5×10^−10)/ 1.2 × 10^−12 × 100/1
% error = 124%

A chemical reaction produces a molecule in which all of the atoms have a stable configuration. Which molecule could be the product of the reaction?
(1 point)
SiO
PH3
MgBr
KCl2
The product of this reaction is PH3. All of the atoms in PH3 have a stable configuration.
According to the octet rule, atoms are stable when they have two or eight electrons around their outermost shell. A stable configuration is one in which the outermost shell is fully filled with eight electrons.
The reason behind chemical combination is to enable atoms attain this stable configuration. If we look at the compound, PH3, we will notice that phosphorus has eight electrons around its outermost shell while each hydrogen atom has two electrons around its outermost shell hence all of the atoms have a stable configuration.

Suppose a solution has a pOH of 5.3. What is the concentration of hydronium ion, H3O+, in the solution?
The concentration of hydronium ion, H3O+, in the solution with pOH of 5.3 is 1.99 × 10-⁹M.
HOW TO CALCULATE HYDROGEN CONCENTRATION:
The pOH of a solution is given as 5.3. The pH of this solution can be calculated as follows:pOH + pH =145.3 + pH = 14pH = 14 - 5.3 = 8.7pH = 8.7.The hydrogen ion concentration can be calculated by using the following expression:[H+] = 10-pH[H+] = 10-⁸.⁷[H+] = 1.99 × 10-⁹MTherefore, the concentration of hydronium ion, H3O+, in the solution with pOH of 5.3 is 1.99 × 10-⁹M.
