M=(mols/L) so M=(9.0/2.5) which is 3.6M
Answer:There are 18 electrons and 17 protons, so the chlorine atom has become a charged chlorine ion with a charge of negative one (-1). ... When it does, the sodium atom becomes a sodium ion with a charge of positive one (+1). Chlorine, as mentioned above, desperately wants an electron so it can fill its outer electron level.
Answer:
The answer is D) all of the above
Explanation:
This is because if something has mass then it is composed of matter.
Can I have brainliest please?
Answer:
The new volume is 1.62 L
Explanation:
Boyle's law says:
"The volume occupied by a given gas mass at constant temperature is inversely proportional to the pressure." It is expressed mathematically as:
Pressure * Volume = constant
o P * V = k
Charles's law is a law that says that when the amount of gas and pressure are kept constant, the ratio between volume and temperature will always have the same value:

Gay-Lussac's law indicates that when there is a constant volume, as the temperature increases, the gas pressure increases. And when the temperature is decreased, the gas pressure decreases. So this law indicates that the quotient between pressure and temperature is constant.
Gay-Lussac's law can be expressed mathematically as follows:

Combined law equation is the combination of three gas laws called Boyle's, Charlie's and Gay-Lusac's law.

Having an initial state 1 and a final state 2 it is possible to say that:

Standard temperature and pressure (STP) indicate pressure conditions P = 1 atm and temperature T = 0 ° C = 273 ° K. Then:
- P1= 1 atm
- V1= 1.2 L
- T1= 273 °K
- P2= 0.80 atm
- V2= ?
- T2= 21°C= 294 °K
Replacing:

Solving:

V2= 1.62 L
<u><em>The new volume is 1.62 L</em></u>

The substances which allow the current to flow in the circuit are:
Lithium bromide in a solution and Graphite.
Lithium bromide can be pass the current in the circuit, due to the ability to form ions in the solution Li⁺ and Br⁻ which are mobile and can transport the electrical charge.
In the graphite because of the presence of delocalised electrons, each carbon atom forms three covalent bonds with three other carbon atoms, it conducts electrical current.
In the case of potassium chloride lattice there are in a solid form and the atoms are not mobile so they can not form ions. In the diamond all the carbon valences are satisfied so the electrical charge can not be transported.
Nitric oxide in a solution is isolated and can not transport the electrical current due to its inability of the to form ions
