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.

The given electronic configuration 1s²2s²2p⁶3s²3p⁶4s²3d⁸ is the Nickel (Ni). Therefore, option (B) is correct.

The electron configuration can be explained as electrons being filled in different energy levels of an atom of a particular element. In the electron configuration, the number of electrons is usually written as a superscript of atomic subshells. For example, the electron configuration of Oxygen is written as 1s²2s²2p⁴.

The sequence of fully filled subshells that correspond to the electronic configuration of a noble gas is denoted by square brackets. The principal quantum number (n) can be used to evaluate the maximum number of electrons in an electron shell.

The value of 2n² is given the maximum number of electrons. The atomic orbitals at low energy must be filled first occupying an orbital with a higher energy level.

The total number of electrons filled in the given electronic configuration  1s²2s²2p⁶3s²3p⁶4s²3d⁸  is 28. The atomic number of Nickel is 28 therefore it is the configuration of Nickel.

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.

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.

The mass of H2O is produced by the combustion of 1.00 mol of CH4 is 36.0 grams.

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.

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%

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).
