Explanation:

Calcium oxide (CaO) forms when an atom of calcium loses two electrons, giving it a +2 charge and an atom of oxygen picks up two electrons, giving it a -2 charge. What is calcium oxide?. A.) An element B.) A covalently bonded compound C.)An ionically bonded compound.

Answers

its C

An ionic bonded compound as the bond is formed from a metal and a non metal plus its a strong electrostatic attraction between 2 or more elements

hope that helps

The answer for the question above is letter "C. an ionically bonded compound." As it was already explained in this item, the bond between the atoms of calcium and oxygen to form the calcium oxide is formed through the transfer of electrons from one atom to another.

No two electrons in an atom can have exactly the same quantum numbers. Orbital quantum numbers tell you what energy level the electron is in. In the Bohrmodel, this represents how high the orbit is above the nucleus; higher orbits have more energy

What is the mass percentage of carbon in 5.000 G of sucrose

Answers

Answer : The mass percentage of carbon in sucrose is, 42.1 %

Explanation: Given,

Molar mass of C = 12 g/mole

Molar mass of H = 1 g/mole

Molar mass of O = 16 g/mole

First we have to calculate the molar mass of sucrose.

Molar mass of sucrose $(C_(12)H_(22)O_(11))$ = $12(12)+22(1)+11(16)=342g/mole$

Now we have to calculate the mass of carbon in 5 g of sucrose.

As we now that there are 12 number of carbon atoms, 22 number of hydrogen atoms and 11 number of oxygen atoms.

The mass of carbon = $12* 12=144g$

As, 342 g of sucrose contains 144 g of carbon

So, 5 g of sucrose contains $(5)/(342)* 144=2.105g$ of carbon

Now we have to calculate the mass percentage of carbon in sucrose.

Formula used :

$\%\text{ Mass percentage of carbon}=\frac{\text{Mass of carbon}}{\text{Mass of sucrose}}* 100$

Now put all the given values in this formula, we get:

$\%\text{ Mass percentage of carbon}=(2.105)/(5)* 100=42.1\%$

Therefore, the mass percentage of carbon in sucrose is, 42.1 %

17) 8.4 / 20 x 100

18) 20 . 0.5150

19) 6,50% because (as you said) the law of definite proportions states that regardless of the amount, a compound is always composed of the same elements in the same proportion by mass

An atom has 6 electrons in its valence shell. how many unpaired electrons does it have?

Answers

Final answer:

An atom with six electrons in its valence shell will have two unpaired electrons. The four electrons will occupy two orbitals fully, while the remaining two electrons will each occupy one orbital in accordance with Hund's Rule.

Explanation:

An atom with six electrons in its valence shell typically belongs to group 16 on the periodic table. In this group, Oxygen is a perfect example having 'six valence' electrons but only 'two of them are unpaired'. The four electrons are arranging themselves in two fully occupied orbitals, while the remaining two electrons each occupy one orbital, following Hund's Rule, which states that orbitals in the same subshell fill with one electron first, with spins parallel, before they begin to pair up. Therefore, an atom with six electrons in its valence shell would have two unpaired electrons.
