Look in the Periodic Table at groups; sodium has the valence +1, magnesium +2 and chlorine -1.

How to find valency of PO4?
PO4^-3 is an ion.So its valency is -3
How do you find out valency of mixture or compound?
To find the valency of a mixture or compound, you need to know the individual valencies of the elements involved. Valency is determined by the number of electrons an atom gains, loses, or shares to achieve a stable electron configuration. For example, in water (H2O), hydrogen has a valency of +1 and oxygen has a valency of -2, resulting in a compound with a total valency of zero.
How do you take out valency an element?
Group number 1 = Valency 1+group number 2 = valency 2+group number 3 = valency 3+group number 4 = valency 4+ and 4- (some cases) group number 5 = valency 3-group number 6 = valency 2-group number 7 = valency 1-group number 8 = valency 0For the transition elements they will either state Copper (III) Sulphate or it will be like Cu2(SO4)3You can find the valency by the base of sulphate and you know its positive because metals are always positive and are written in the left.Source: I am a GCE O Level Sciences Student (O2)
What is table salt in the periodic table?
Table salt, or sodium chloride, is a compound composed of two elements: sodium (Na) and chlorine (Cl). Sodium is a metallic element found in Group 1, Period 3 of the periodic table, while chlorine is a nonmetallic element found in Group 17, Period 3 of the periodic table.
How do you find the valency of atoms?
by knowing the no. of electorns in its outermost shell
What elements would you find in sea water?
Chlorine, Sodium, Magnesium, Sulphur, Calcium, Potassium, Bromine, Boron, Strontium and Silicon. Oh yeah...and Hydrogen and Oxygen.
How many grams of Chlorine are in 7 grams of Sodium Chloride?
To find the answer, we multiply the 7 grams of NaCl by the ratio of the molar mass of chlorine over the molar mass of sodium chloride. By doing this, we find that there are about 4.25 grams of chlorine in 7 grams of NaCl.
Where is chlorine located in body?
Chlorine is very active element. It readily combine with any organic matter. So you do not find free chlorine in your body. You find the chlorine as sodium chloride out side the cells. You find double amount of chlorine in, potassium chloride, that is present inside the cells.
What would be the correct formula for sodium bromate considering that chlorine and bromine are in the same family in the periodic table?
The correct formula for sodium bromate would be NaBrO3. It is formed from sodium (Na), bromine (Br), and oxygen (O), following the typical valency of elements in the same family on the periodic table.
What mass of sodium chloride is formed if 22.99 grams of sodium combines with 35.54 grams of chlorine?
The molar mass of sodium chloride is 58.44 g/mol. To find the mass of sodium chloride formed, you need to compare the moles of sodium and chlorine to determine the limiting reactant. Calculate moles of sodium and chlorine, determine limiting reactant, and use stoichiometry to find mass of sodium chloride formed.
Does sodium propionate contain iodine?
Chlorine is not a compound, it is an element. That means that if you have a pure sample of chlorine then it will not contain iodine, or anything other than chlorine. It would be somewhat unlikely to find iodine as an impurity in chlorine, because iodine is solid at room temperature while chlorine is a gas.
How do you find the chemical formula of sodium oxide?
Well you should know the formula and valency of each element first, Sodium formula - Na valency - +1 Oxide formula - Oxygen - O valency - (-2) Since the charge of the compound has to be 0 (zero) 2 atoms of sodium (+2) are required to neutralize the effect of the one oxygen atom (-2) ----------- [2 + (-2) = 0] Na2O
What mass of chlorine gas will react with 92.0g of sodium?
The reaction between sodium and chlorine gas occurs in a 1:1 molar ratio. The molar mass of chlorine gas is 71 g/mol. To find the mass of chlorine that will react with 92.0 g of sodium, first convert 92.0 g of sodium to moles, then use the 1:1 ratio to calculate the mass of chlorine gas needed.
How to find valency of PO4?
PO4^-3 is an ion.So its valency is -3
What mass of chlorine gas will react with 92 grams of sodium?
The balanced chemical equation for the reaction between chlorine gas and sodium is: 2Na + Cl2 -> 2NaCl Using the equation, we can see that 1 mole of chlorine gas (Cl2) reacts with 2 moles of sodium (2Na). To calculate the mass of chlorine gas needed to react with 92 grams of sodium, first convert 92 grams of sodium to moles, then use the mole ratio from the balanced equation to find the moles of chlorine gas needed. Finally, convert the moles of chlorine gas to grams.
Compare the chemicals or minerals found in tap water and new water?
In our tap water, you can find minerals such as: sodium, potassium, manganese , iron, copper and calcium. The chemicals are typically just chlorine and fluorine. :)
How could you find the salt concentration of salt water?
1. By determination of sodium and chlorine. 2. Using a salinometer.
