3- might cause depression or anxiety
4- listening to negative words constantly can make the person’s mind think it’s the truth

A standard solution is a solution (in this case sodium hydroxide) whose concentration (molarity) is known very precisely. <span>The molarity of the sodium hydroxide solution cannot be determined accurately because s</span>olid sodium hydroxide is highly hygroscopic (absorbs water from the air) and cannot be accurately weighed. Sodium hydroxide form sodium carbonate because it absorbs carbon
dioxide from the air.
Answer is: Move from the negatively charged body to the positively charged body.
The electron (symbol: e⁻) is a subatomic particle whose electric charge is negative one elementary charge.
The proton (p⁺) is subatomic particle with a positive electric charge of +1e elementary charge.
Opposite charges (positive and negative) attract one another.
The negatively charged body has extra electrons, more electrons than protons.
The positively charged body has less electrons than protons.
Answer:
![[H^+]=3.16x10^{-4}M](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D3.16x10%5E%7B-4%7DM)
Explanation:
¡Hola!
En este caso, dado que el pH de una solución se entiende como el potencial de los iones hidrógeno en la misma, es posible recordar la ecuación que se usa para calcularlo:
![pH=-log([H^+])](https://tex.z-dn.net/?f=pH%3D-log%28%5BH%5E%2B%5D%29)
De este modo, al conocer el pH, se resuelve para la concentración de iones hidrógeno como se muestra a continuación:
![[H^+]=10^{-pH}](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D10%5E%7B-pH%7D)
Así, reemplazamos el pH para obtener:
![[H^+]=10^{-3.5}=3.16x10^{-4}M](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D10%5E%7B-3.5%7D%3D3.16x10%5E%7B-4%7DM)
¡Saludos!
Answer:
Explanation:
Chemical Compounds are substances that are made up of 2 or more elements that have reacted to each other through a chemical bond to give a different substance to the initial elements.
The chemical formula is an expression used to indicate the molecular composition of a compound. In other words, it indicates by means of symbols the elements that make up the compounds and their proportion.
