The chemical reaction involved in this titration process would be:
NaOH(aq) + KHC8H4O4(aq) = KNaC8H4O4(aq) + H2<span>O(l)
</span>
To determine the concentration of the NaOH solution, we, first, need to calculate the moles of NaOH that is used up in the reaction given the amount of KHP solution that is used. We do as follows:
Moles NaOH = 0.500 M KHP ( .025 L solution ) ( 1 mol NaOH / 1 mol KHP ) = 0.0125 mol NaOH reacted
Volume of NaOH solution used = 53.5 mL - 25.0 = 28.5 mL
Molarity is the number of moles of a solute per liter of solution. We calculate as follows:
Molarity of NaOH = 0.0125 mol / .0285 mL = 0.44 M
Answer:
1.788 × 10⁷ g
Explanation:
Let's consider the following balanced equation.
2 H₂ + O₂ → 2 H₂O
We can establish the following relations.
- The molar mass of H₂ is 2.016 g/mol.
- The molar ratio of H₂ to H₂O is 2:2.
- The molar mass of H₂O is 18.02 g/mol.
The mass of H₂O obtained from 200.0 kg (200.0 × 10³ g = 2.000 × 10⁶ g) of H₂ is:
Answer:
GM is a technology that involves inserting DNA into the genome of an organism. To produce a GM plant, new DNA is transferred into plant cells. Usually, the cells are then grown in tissue culture where they develop into plants.Explanation:
im pretty sure its B. though i hope this helps
