Why was einstein not happy with the probable positions of electrons in the orbitals?
Naddik [55]

Since electron orbitals are described as probability clouds, Einstein disagreement with the probable positions of electrons in the orbitals is that, It is not possible to know the orbit of an electron when the position is under probability.

According to Bohr's theory, it is difficult to locate electron or cannot be located in a definite region. Electron has to be found in an orbit and nowhere else. When the probability of finding an electron in a given spherical shell around the nucleus is plotted the distance of the electron from the nucleus for the hydrogen atom, the graph indicates that the probability of finding the electron increases as the distance between the electron and the nucleus decreases

Bohr claimed that electrons a entities had only probabilities if they weren't observed. While Einstein argued that they had independent reality.

But in wave mechanics Model, there is a slight chance of knowing the location of the electron.

Heisenberg uncertainty principle also claim the possibility of knowing the position of electron. Albert Einstein also claim that; to determine the position of an electron to an accurate extent, you would have to compromise your ability to know it's momentum. This inaccuracy will eventually affect the measurement of momentum which will be extremely uncertain.

Since electron orbitals are described as probability clouds, Einstein disagreement with the probable positions of electrons in the orbitals is that, It is not possible to know the orbit of an electron when the position is under probability.

Identify whether each species functions as a Brønsted-Lowry acid or a Brønsted-Lowry base in this net ionic equation.CH3COO-+HCO
NARA [144]

Explanation :

According to the Bronsted Lowry concept, Bronsted Lowry-acid is a substance that donates one or more hydrogen ion in a reaction and Bronsted Lowry-base is a substance that accepts one or more hydrogen ion in a reaction.

Or we can say that, conjugate acid is proton donor and conjugate base is proton acceptor

The given equilibrium reaction is,

CH_3COO^-+HCO_3^-\rightleftharpoons CH_3COOH+CO_3^{2-}

In this reaction, CH_3COO^- and HCO_3^- are act as Bronsted Lowry base and acid respectively and CH_3COOH and CO_3^{2-} are act as Bronsted Lowry acid and base respectively.

The formula of conjugate of CH_3COO^- is, CH_3COOH

The formula of conjugate of HCO_3^- is, CO_3^{2-}

How long is a frozen turkey good for in the freezer?
Dmitrij [34]

Answer: Turkeys are good  for up to 2 years if frozen well in a good freezer

I recommend to at least cooking it within 1 year for the best quality if you cook it in 2 years it may lose some of its quality taste-wise.

if it's not frozen well check the texture and smell to see if its gone bad. it also depends on the type of turkey you are buying, depending on the turkey you purchase always check for an expiration date such as a butterball turkey,  so make sure you check their date.
