Why pie bond are not perticipate in hybridaization​
DedPeter [7]
The first bond between two atoms is always a sigma bond and the other bonds are always pi bonds and a hybridized orbital cannot be involved in a pi bond. Thus we need to leave one electron (in case of Carbon double bond) to let the Carbon have the second bond as a pi bond.

Which of the following contains the same number of electrons as an atom of neon?
asambeis [7]

Answer:

D. O^{2-}

Explanation:

In Chemistry, electrons can be defined as subatomic particles that are negatively charged and as such has a magnitude of -1.

Valence electrons can be defined as the number of electrons present in the outermost shell of an atom. Valence electrons are used to determine whether an atom or group of elements found in a periodic table can bond with others. Thus, this property is typically used to determine the chemical properties of elements.

Oxygen has a total number of eight (8) electrons and as such the O^{2-} is able to gain (receive) two (2) more electrons in order to have the same electron arrangements as the noble gas i.e an atom of neon that has a total number of ten (10) electrons.

Hence, O^{2-} contains the same number of electrons as an atom of neon.

A chemist determined by measurements that 0.0500 moles of nickel participated in a chemical reaction. Calculate the mass of nick
Rashid [163]

Answer:

2.94 grams Nickle

Explanation:

All they are asking is to convert moles to grams

To do this, find the atomic mass of nickel using the periodic table: 58.693 g

0.05 mol * 58.693 g/1 mol = 2.93465 grams

Explain how the particles of air inside the balloon create pressure
lora16 [44]

Inside the balloon, the gas particles collide with the balloon's inner walls. ... As the molecules heat up, they move faster and strike the inside wall of the balloon harder. This increased motion of the gas particles increases the force on an area of the balloon, producing a rise in the pressure.

mark me brainliestttt :))
