Answer:
synthesis reaction
Explanation:
A synthesis reaction occurs when two or more reactants combine to form a single product. In a decomposition reaction, one reactant breaks down into two or more products. This is the reverse of a synthesis reaction. Replacement reactions occur when elements switch places in compounds.
Answer:
0.2M H2C6H5O7 < 0.2M H2C2O4
Explanation:
A weak acid/base ionizes to a very small extent in water. Hence, if we say that a substance is a weak acid/base, its percentage of ionization in solution is very little.
More volume of a very weak acid is required to neutralize a strong base. Since NaOH is a strong base, the weaker acid among the duo will require more volume for neutralization.
Since H2C6H5O7 is a weaker acid than H2C2O4, equal concentration of the both acids will require less volume of H2C2O4 than H2C6H5O7 to neutralize 0.50 M NaOH.
Fe2(SO4)3 + 6KOH -> 3K2SO4 + 2Fe(OH)3
The moles of magnesium in 1.25 x 1023 are 20.8 mol.
Answer:
0.20 moles
Explanation:
In order to solve this problem it is necessary to keep in mind the definition of molarity:
- Molarity = moles / liters
If we<u> input the data given by the problem</u> we're left with:
Meaning that we can proceed to <u>calculate the number of moles</u>:
