electron is, on average, close to the nucleus: an electron in a 2s orbital or an electron in a 3s orbital is electrons . The electron in 2s orbital are closer to the nucleus than those of 3s orbital.

The 3s orbital electron posses more energy than those electrons in  2s orbital. The size of orbital is determine by the principal quantum number n. The higher the value of n , the farther the orbital from the nucleus . And same as the electron situated to orbital.

Thus, electron is, on average, close to the nucleus: an electron in a 2s orbital or an electron in a 3s orbital is electrons . The electron in 2s orbital are closer to the nucleus than those of 3s orbital.

a 1.912 g samplw of calcium chloride is decomposed and found to contain 0.690 g of Ca and 1.222 g of Cl. Calculate the mass perc
adoni [48]

Answer:

36.09% is the mass percent composition of calcium in calcium chloride

Explanation:

Mass percent is defined as one hundred times the ratio between the mass of a compound (In this case, Calcium), and the total mass of the sample:

<em>Mass Percent = Mass compound / Total mass of the sample × 100</em>

<em />

Computing the values of the problem:

Mass Percent = 0.690g / 1.912g * 100

Mass percent =

<h3>36.09% is the mass percent composition of calcium in calcium chloride</h3>

Photosynthesis can be represented by6CO2(g)+6H2O(l)⇌C6H12O6(s)+6O2(g)Which of the following will be false when the photosynthesi
denis-greek [22]

Answer:

The concentration of O2 will begin decreasing and The concentrations of CO2 and O2 will be equal.

Explanation:

Equilibrium occurs when the velocity of the formation of the products it's equal to the velocity of the formation of the reactants, thus the concentrations of the compounds remain constant.

Analyzing the information and the reaction given, we can notice that in equilibrium the rate (velocity) of formation of O2 (product) is equal to the rate of formation of CO2 (reactant).

As the CO2 and H2O are placed in the reaction, the Le Chateliêr's principle states that the equilibrium must shift to reestablish the equilibrium, thus, they must be consumed, and the concentration of O2 must increase.

As state above, in equilibrium, the concentrations didn't change, thus, the concentrations of CO2 and O2 will not change.

The concentrations of CO2 and O2 depends on the rate of the reaction and the initial quantities presented, so it's not possible to affirm they'll be equal.

Why does the sky change colors at sunrise and sunset
aniked [119]

Answer:

As the sun's angle changes, (because of the rotation of the earth) the sun slowly begins to shine more or less sunshine slowly. When sunsets and sunrises occur, the color of the sky changes because the sunshine is starting to fade out or in.

I put it in my own words so you don't have to worry about plagiarism :)

1) According to Bohr's model of the atom, in which orbitals do electrons have the most energy?
Alex Ar [27]

The orbitals closest to the nucleus is the orbital wih the lowest energy. This is according to the basic rules stating that the energy of the shells as its principal quantum number increases, also increases. Thus the answer in 1 is B. Valence electrons are found in the outermost electron shell, on the other hand.
