Sodium Chloride is a compound.
Answer: Ionic formula will be 
.
Explanation: 
and 
ions will form a ionic compound. Ionic compounds have both metals and non-metals.
Here is a metal and is a non-metal.
The net charge on any compound must be 0.
So we need 2 phosphate ions to balance the charge on ions. Similarly we need 3 Magnesium ions to balance the charge on ions.
Criss-crossing the charges, we will get the formula as
Criss-crossing is shown in the image below.
Answer:
Increase D ⇒ rightward shift
Increase E ⇒ rightward shift
Increase F ⇒ leftward shift
Decrease D ⇒ leftward shift
Decrease E ⇒ leftward shift
Decrease F ⇒ rightward shift
Triple D and reduce E to one third ⇒ no shift
Triple both E and F ⇒ no shift
Explanation:
Changes in the concentrations of reactants y products affect to the equilibrium. In this case, D and E are reactants and F is the product.
When a change in the factors affecting equilibrium occur, the system will react in order to counteract the change imposed.
- If a increase of reactant occur, the system will tend to produce more products (<em>rightward shift</em>). For example: increase D, increase E. In contraposition, if a decrease of reactant occur, the system will produce more reactants (<em>leftward shift</em>). For example: decrease D, decrease E.
- If a increase of product occur, the system will tend to produce more reactants (<em>leftward shift</em>). For example: increase F. In contraposition, if a decrease of product occur, the system will produce more products (<em>rightward shift</em>). For example: decrease F.
- If we change both reactants and products concentration in the same amount, the net change is zero, so there is <em>not shift</em>. For example: Triple D and reduce E to one third (D x 3 and E/3, there is not change in the total amount of reactants) ; Triple both E and F (E x 3 and F x 3, the net change is zero).
Answer is: because this compound in water dissociates on cations and anions and ions in solution conduct electricity.
Chemical dissociation of acetic acid in water:
CH₃COOH(aq) ⇄ CH₃COO⁻(aq) + H⁺(aq).
When we put electrodes (cathode and anode) in acetic acid solution, positeve and negative ions migrate to electrodes.
Negative acetate ions go to positive electrode and gives electrons to electrode.
Positive hydrogen ions go to negative electrode and gain electrons.
Answer:
Magnesium and strontium
Explanation:
11 protons and 11 electrons, 12 neutrons.
The atomic number of sodium is 11, therefore the number of electrons and protons are 11. The atomic mass is 23, and to find neutrons you need to subtract the atomic number from the atomic mass, therefore the number of neutrons are 12.
