How many more valence electrons does oxygen need to have a full outer valence shell?

Chemistry

Oxygen is in group 16 of the PTOE, so it has 6 valence electrons. In order to have a full outer shell it would need 2 more electrons. (second shell can hold a max of 8 electrons)

The mass of carbon in 1 liter of mixture = 1.108 g

<h3>What is the mass of carbon in 1 liter of the mixture?</h3>

The mass of carbon in 1 liter of the mixture is determined as follows:

First the moles of gas is determined using the ideal gas formula:

  • n = PV/RT

n = (1 * 1)/(0.08205L * 298)

n = 0.0409 mole of total gas

mass of gas is then determined using the formula:

  • mass = density * volume

mass = 1 * 1.375

mass = 1.375 g

Let x = mass of CH₄ and y = mass of C₄H₁₀

x + y = 1.375 g

nCH₄ + nC₄H₁₀ = ntotat

moles = mass/molar mass

x + y = 1.695 => y = 1.695 - x

(x/molar mass of CH₄) + [(1.375 - x)/ molar mass C₄H₁₀ = 0.0409

x/16 + (1.375 - x)/58 = 0.0409

x = 0.380 g CH₄

y = 1.375 - 0.380

y = 0.995 g of C₄H₁₀

mass of C in CH₄ = 12/16 * 0.380 = 0.285

mass of C in C₄H₁₀ = 48/58 * 0.995 = 0.823

Mass of carbon in 1 liter of mixture = 0.285 + 0.823

Mass of carbon in 1 liter of mixture = 1.108 g

In conclusion, the carbon is the major component in the mixture.

Repulsion is a force or interaction among the atoms in a molecule in which the atoms attract one another.
Anni [7]
Repulsion is a force or interaction among the atoms in a molecule in which the atoms REPEL one another. By the word itself repulsion, meaning to repel, it automatically bans the idea of ATTRACTION. Therefore, the statement above is FALSE. The answer to this question is "B. False".

Vincent combines sodium and chlorine in two different beakers (beaker X and beaker Y). In both beakers, the chemical reaction sh
Elza [17]

Answer: A. the chemical change will occur faster in beaker X.

Explanation:

Temperature is one of the factors that affect the rates of chemical reactions. Increase in temperature increases the rates of reaction by increasing the kinetic energy of the reacting particles so that energetic collisions occur and more bonds in the reactants will be broken and; atoms and ions recombine to form new compounds. Beaker X which is at room temperature has higher temperature than beaker Y which is kept in the refrigerator, thus reacting particles in beaker X has more kinetic energy than the ones in beakerA. the chemical change will occur faster in beaker X. Y.

Hi, can someone help me with these<br> why do hydrogen sulfide has a low boiling point
riadik2000 [5.3K]

Hydrogen sulfide has a low boiling point because it is only a slightly polar molecule, meaning that it only has weak dipole-dipole intermolecular forces. Because of its relatively weak intermolecular forces, it has a low boiling point.
