Answer:
A cation is a positively charged ion, with fewer electrons than protons, while an anion is negatively charged, with more electrons than protons. Because of their opposite electric charges, cations and anions attract each other and readily form ionic compounds.
Explanation:
its science
Water is a pure substance, however it is made up of oxygen and hydrogen atoms, hence the nickname H2O (Hydrogen2, Oxygen)
The new volume of the gas is 144 mL.
<u>Explanation:</u>
At STP, the temperature is 273 K an pressure is 1 atm.
1 atm=101kPa
Given that initial volume V1=36 mL
Initial pressure P1=1atm=101 kPa
Final pressure P2=25.3kPa
We have to determine the final volume V2
According to Boyle's law
![P_{1} V_{1} =P_{2} V_{2}](https://tex.z-dn.net/?f=P_%7B1%7D%20V_%7B1%7D%20%3DP_%7B2%7D%20V_%7B2%7D)
![V_{2} =P_{1} V_{1} /P_{2}](https://tex.z-dn.net/?f=V_%7B2%7D%20%3DP_%7B1%7D%20V_%7B1%7D%20%2FP_%7B2%7D)
![=25.3\times101/25.3](https://tex.z-dn.net/?f=%3D25.3%5Ctimes101%2F25.3)
=144 mL
Final volume =144mL
