which of these is a rough approximation of the cogito?
Given the Latin meaning of the cogito, we can confirm that it is roughly translated and summarized by the phrase "I think, therefore I am".
Cogito, ergo sum or "The Cogito" is an extremely popular, well-known philosophical phrase credited to Rene Descartes. This Latin phrase is roughly translated as "I think, therefore I am", which appeared originally in "The Principles of Philosophy", and was later translated to a variety of languages in an attempt to reach a wider public, most notably into Latin.

How does vapor pressure affect intermolecular forces.
Answer:
it is directly related to the intermolecular forces present between its molecules
Phosphorus reacts with oxygen to form diphosphorus pentoxide: 4 P(s) 5 O 2(g) ---> 2 P 2O 5(s) If 0.97 moles of phosphorus are reacted how many moles of P 2O 5 are produced
4P(s)+5O2(g)-->2P2O5(s)
4 moles of P=2moles of P2O5
0.97 moles of P=(2*0.97)/4
=0.485 moles

How many moles of iron(III) oxide, Fe2O3 , will be produced if 12 moles of oxygen gas, O2 , are consumed
Answer:
8 moles of Fe2O3
Explanation:
You can use the mole ratio give. For every 3 O2 you produce 2 Fe2O3. With this you can find the number of moles. 12 O2 multiplied by the ratio 2/3 gives you 8 moles

Which element has 1 valence electron in its outer shell and will react with a
group 17 element in a 1:1 ratio?
Answer:
sodium (Name) and Chlorine (Cl)
Explanation:
Any of the Group 17 elements (the halogens) only need one additional electron to take on the electron configuration of the noble gas just to it's right. That would be argon (Ar) in this case.
For this reaction, the needs of both elements (to reach a stable Group 17 electron configuration) is matched: Just one electron is provided (Na) and taken (Cl) and that forms a single bond
Answer please
.............................................................
This is not exactly a answer you can use but this is some information that you can use to find out the answer.
You can usually confirm the charge associate degree particle unremarkably has by the element's position on the periodic table: The alkali metals (the IA elements) lose one negatron to create a ion with a 1+ charge. The alkaline-earth metal metals (IIA elements) lose 2 electrons to create a 2+ ion.
Nonmetals type negative ions (anions). A range 7|chemical element|element|gas} atom should gain 3 electrons to possess an equivalent number of electrons as AN atom of the subsequent gas, neon. Thus, a gas atom can type AN ion with 3 additional electrons than protons and a charge of 3−.

The following image shows what happens when the particles in a certain state occupy a space. What is the state of the substance that is occupying the space and how do you know?
A. The substance is a gas because the particles are spreading out to fill the space of the container.
B. The substance is a liquid because the particles inside are taking the shape of the container.
C. The substance is a mixture of a gas and a liquid because the particles are filling the space of the container.
D. The substance is a solid because the particles inside the box have a definite shape.
Answer:
A
Explanation:
The substance is a gas because the particles far randomly arranged and far apart from each other. This happens because when a substance is a gas, particles have weak attraction to each but a lot more kinetic energy which means the they move around all the time spreading out to fill the container. If it was a solid, then all the particles would be very close together and have a fixed position and if it was a liquid then the particles would be fairly close and moving around each other but as we can see in the diagram, all the particles are far apart confirming that it is a gas.

what aspects are not accounted for in the ideal gas law?
The aspects not accounted for in the ideal gas law are the force of attraction of the gas molecules on each other and the volume of the gas molecules.
In the ideal gas law, it it assumed that the molecules of the gas are so far away from each other and thus they do not exert a significant force of attraction on each other. Also, the volume of each molecule of gas is neglected and assumed negligible and thus does not account for the overall volume of the gas.
So, the aspects not accounted for in the ideal gas law are the force of attraction of the gas molecules on each other and the volume of the gas molecules.

List the 7 diatomic elements in the periodic table.
Question 5 options:
All alkaline earth metals- Be, Mg, Ca, Sr, Ba,Ra.
All elements in the periodic table are diatoms.
H2, N2, O2,F2, Cl2, Br2, I2
All group 16 elements-O, S, Se, Te, Po.
Answer:
Group 2A (or IIA) of the periodic table are the alkaline earth metals: beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). They are harder and less reactive than the alkali metals of Group 1A. The name comes from the fact that the oxides of these metals produced basic solutions when dissolved in water, and they remained solids at the temperatures available to the ancient alchemists. Like the Group 1A elements, the alkaline earth metals are too reactive to be found in nature in their elemental form.
The alkaline earth metals have two valence electrons in their highest-energy orbitals (ns2). They are smaller than the alkali metals of the same period, and therefore have higher ionization energies. In most cases, the alkaline earth metals are ionized to form a 2+ charge.
The alkaline earth metals have much higher melting points than the alkali metals: beryllium melts at 1287ºC, magnesium at 649ºC, calcium at 839ºC, strontium at 768ºC, barium at 727ºC, and radium at 700ºC. They are harder metals than the Group 1A elements, but are soft and lightweight compared to many of the transition metals.
Salts of the Group 2A metals are less soluble in water than those of Group 1A because of the higher charge densities on the 2+ cations; nevertheless, many Group 2A salts are at least moderately soluble. Some Group 2A salts bond strongly to water molecules, and crystallize as hydrates; among these are Epsom salt, MgSO4·7H2O, and gypsum, CaSO4·2H2O.

Which ground-state atom has an electron configuration described by the following orbital diagram?.
Answer:
The energy of atomic orbitals increases as the principal quantum number, n, increases. In any atom with two or more electrons, the repulsion between the electrons makes energies of subshells with different values of I differ so that the energy of the orbitals increases within a shell in the order s< p <d<f. Figure 1 depicts how these two trends in increasing energy relate. The 1s orbital at the bottom of the diagram is the orbital with electrons of lowest energy. The energy increases as we move up to the 2s and then 2p, 3s, and 3p orbitals, showing that the increasing n value has more influence on energy than the increasing I value for small atoms. However, this pattern does not hold for larger atoms. The 3d orbital is higher in energy than the 4s orbital. Such overlaps continue to occur frequently as we move up the chart.

How many grams of solid sodium acetate should be added to 2.00 L of 0.184 M acetic acid solution to prepare a buffer with a pH of 4.140
pH = pKa + log [NaAc]/[HAc]
4.140 = 4.74 + log x
log x = -0.60
x = [NaAc]/[HAc] = 0.25
moles HAc = 1.50 L x 0.287 mol/L = 0.431 moles
moles NaAc = 0.25 x 0.431 = 0.1078 moles NaAc
grams NaAc = 0.108 x 80 g/mole = 8.64 grams
