The balance chemical reaction describing the reaction between Mg2+ and Cl- is shown below,
Mg2+ + 2Cl- ----> MgCl2
This is a reaction where there is a transfer of electrons. Since the valence electron of Mg2+ is 2 and that of Cl- is only 1. There is a need for 2 Cl- to react with 1 Mg2+ in order to balance the equation.
Thus, the anwer is MgCl2.
Answer
Omega-3 fatty acid
Explanation:
The monomers are small units or molecules which join with each other end in a huge to end and give rise to the polymers.
DNA and albumin:
If we talk about albumin it is a protein which is present in eggs. All proteins are made up of monomers of amino acids. Similarly, DNA is also a polymer because it is made up hundreds and thousands of small monomeric units called nucleotides.
glycogen:
It is also a biological polymer where several monomer units of glucose are joined together through alpha acetal linkages.
Omega-3 fatty acid:
It is not a polymer. Its a group of fatty acids that contain a double bond at carbon of 3rd position from one end of the carbon chain that was initiated from methyl group and contains one carboxyl group located at the other molecular end. For example: Alpha-Linelenic acid.
Therefore, Omega-3 fatty acid is the right option.
Hope it helps!
Answer:
The answer to your question is: C₂H₆O₁ = C₂H₆O
Explanation:
Data
CxHyOz
mass = 40 g produced 76.40 g of CO2
46.96 g of H2O
Empirical formula = ?
Process
CxHyOz + O2 ⇒ CO2 + H2O
44g of CO2 -------------------- 12 g of Carbon
76.40 g of CO2 --------------- x
x = 20.84 g of Carbon
12 g of Carbon --------------- 1 mol
20.84 g of C --------------- x
x = (20.84 x 1) / 12
x = 1.74 mol of Carbon
18 g of H2O -------------------- 2 g of H
46.96 g of H2O -------------- x
x = (46.96 x 2) / 18
x = 5.22 g of H
1 g of H ------------------------ 1 mol of H
5.22 g of H ------------------- x
x = 5.22 mol of H
Mass of Oxygen = 40 - 20.84 - 5.22g
= 13.94 g
16 g of Oxygen ---------------- 1 mol
13.94 g of O -------------------- x
x = 0.87 mol of O
Divide by the lowest number of moles
Carbon = 1.74 / 0.87 = 2
Hydrogen = 5.22 / 0.87 = 6
Oxygen = 0.87 / 0.87 = 1
Empirical formula
C₂H₆O₁ = C₂H₆O
According to Arrhenius definition of acid bases: An acid donates ions in aqueous solution and a base donates hydroxide ions in aqueous solution.
So the given statement that a substance that forms hydroxide ions in aquoeus solution is true.
Example of a base giving hydroxide ions in water:
Answer:
I think that volumic mass is like weight of an object, or like the space it takes up??
