How many electrons each atom gives or takes in KBr

Electrons in Bohr's model of the atom are at the lowest possible energy state when they are

arlik [135]

Answer:

d. at ground state

Explanation:

Electrons in the Bohr's model of the atom are at the lowest possible energy state when they are their ground state.

The lowest energy state available to an electron is the ground state.

According to the the Bohr's model of the atom, the extranuclear part is made up of electrons in specific spherical orbits around the nucleus.
In the excited state, the level is higher than the ground state.
When electrons changes state they either absorb or gain energy.

A gas exerts a pressure of 2.5 ATM at a temperature

tino4ka555 [31]

(P1/T1)=(P2/T2)

In an experiment, 2.54 grams of copper completely reacts with sulfur, producing 3.18 grams of copper(I) sulfide.

kozerog [31]

Answer:

0.64 g of S

Solution:

The balance chemical equation is as follow,

2 Cu + S ----> Cu₂S

According to equation,

127 g (2 mole) Cu produces = 159 g (1 mole) of Cu₂S

So,

2.54 g Cu will produce = X g of Cu₂S

Solving for X,

X = (2.54 g * 159 g) / 127 g

X = 3.18 g of Cu₂S

Now, it is confirmed that the reaction is 100% ideal. Therefore,

As,

127 g (2 mole) Cu required = 32 g (1 mole) of S

So,

2.54 g Cu will require = X g of S

Solving for X,

X = (2.54 g * 32 g) / 127 g

X = 0.64 g of S
