The carbon-oxygen single bond in a carboxylic acid
Answer: Metals bond with metals.
Explanation: A metallic bond is a sharing of electrons between many atoms of a metal element. Metallic bonding is when positive ions (metals) are in a 'sea of negative electrons'. The electrons are delocalised, which means they can move around easily and carry charge, and this enables it to conduct electricity, even in a solid state. The big pool of electrons is like a free-for-all in that any valence electron can move to any atom within the material.

Answer:
atoms of isotopes of an element have different numbers of neutrons.
Explanation:
isotopes have the same number of protons, but different numbers of neutrons.
Answer : The final number of moles of gas that withdrawn from the tank to lower the pressure of the gas must be, 0.301 mol.
Explanation :
As we know that:
![PV=nRT](https://tex.z-dn.net/?f=PV%3DnRT)
At constant volume and temperature of gas, the pressure will be directly proportional to the number of moles of gas.
The relation between pressure and number of moles of gas will be:
![\frac{P_1}{P_2}=\frac{n_1}{n_2}](https://tex.z-dn.net/?f=%5Cfrac%7BP_1%7D%7BP_2%7D%3D%5Cfrac%7Bn_1%7D%7Bn_2%7D)
where,
= initial pressure of gas = 24.5 atm
= final pressure of gas = 5.30 atm
= initial number of moles of gas = 1.40 moles
= final number of moles of gas = ?
Now put all the given values in the above expression, we get:
![\frac{24.5atm}{5.30atm}=\frac{1.40mol}{n_2}](https://tex.z-dn.net/?f=%5Cfrac%7B24.5atm%7D%7B5.30atm%7D%3D%5Cfrac%7B1.40mol%7D%7Bn_2%7D)
![n_2=0.301mol](https://tex.z-dn.net/?f=n_2%3D0.301mol)
Therefore, the final number of moles of gas that withdrawn from the tank to lower the pressure of the gas must be, 0.301 mol.
