<u>Answer:</u> The chemical formula of the compound formed is ![H_2SO_4](https://tex.z-dn.net/?f=H_2SO_4)
<u>Explanation:</u>
Acids are defined as the chemical species which donate hydrogen ions when dissolved in water.
![HA(aq.)\rightarrow H^+(aq.)+A^-(aq.)](https://tex.z-dn.net/?f=HA%28aq.%29%5Crightarrow%20H%5E%2B%28aq.%29%2BA%5E-%28aq.%29)
Ionic compound is formed by the complete transfer of electrons from 1 atom to another atom. The cation is formed by the loss of electrons by metals and anions are formed by gain of electrons by non metals.
We are given:
An anion having chemical formula
named as sulfate ion
This will combine with 2 hydrogen ions to form a neutral compound. The neutral compound formed is sulfuric acid.
Hence, the chemical formula of the compound formed is ![H_2SO_4](https://tex.z-dn.net/?f=H_2SO_4)
Answer:
Explanation:
OK this is simple
i'll try to do the unanswered question
CaCl2
In the table
You look for calcium,Ca you fill 1
THen for Chloride=2
i hope you've understood
All eukaryotic cells have a cell surface membrane (aka plasma membrane). It is very fragile. its role is to hold the cell together and to help control what substances can get in and out. (It is partially permeable) allowing only some substances to pass through it.
Answer : The moles of sucrose used in the recipe are, 1.11 moles.
Explanation : Given,
Mass of sucrose = 380 g
Formula used :
![\text{Moles of sucrose}=\frac{\text{Mass of sucrose}}{\text{Molar mass of sucrose}}](https://tex.z-dn.net/?f=%5Ctext%7BMoles%20of%20sucrose%7D%3D%5Cfrac%7B%5Ctext%7BMass%20of%20sucrose%7D%7D%7B%5Ctext%7BMolar%20mass%20of%20sucrose%7D%7D)
Molar mass of sucrose = 342.3 g/mole
Now put all the given values in the above formula, we get:
![\text{Moles of sucrose}=\frac{380g}{342.3g/mol}=1.11mole](https://tex.z-dn.net/?f=%5Ctext%7BMoles%20of%20sucrose%7D%3D%5Cfrac%7B380g%7D%7B342.3g%2Fmol%7D%3D1.11mole)
Therefore, the moles of sucrose used in the recipe are, 1.11 moles.
Answer:Sodium ions
Explanation:
The membrane potential of most cells is negative, when sodium ions enters the cells, it can reverse the polarity and makes it positively charge.
