Answer: According to the Arrhenius concept, an acid is a substance that causes an increase in the concentration of H in aqueous solutions
Explanation:
According to the Arrhenius concept, an acid is a substance that ionizes in the water to give hydronium ion or hydrogen ion and a bases is a substance that ionizes in the water to give hydroxide ion .
According to lewis concept , an acid is a substance that accepts electrons and a base is a substance that can donate electrons.
Answer:
An oxidation reaction
Explanation:
Only one reaction happened and no reduction occurs.Hence, this the redox reaction does not happen.
The amount if protons is the same as the amount of electrons, so it would be 8. The charge is -2. Look at oxygen in the periodic table.
Each atom will be attracted to both nuclei if the two atoms get close then the nuclei will repel each other
Answer:
18.45 g of C
Explanation:
This is a problem of rules of three:
1 mol of C₃H₈ contains 3 moles of C and 8 moles of H
If 8 moles of H are contained in 1 mol of propane
4.10 moles of H are contained in (4.1 . 1) /8 = 0.5125 moles
Now, If 1 mol of propane contains 3 moles of C
0.5125 moles of propane may contain (0.5125 . 3) / 1 = 1.5375 moles of C
Let's convert the moles to mass:
1.5375 mol . 12 g /mol = 18.45 g
