Answer:
0.425M NaOH assuming the volume of KHP was 25.50mL and the volume of the NaOH solution was 30.0mL
Explanation:
The KHP reacts with NaOH as follows:
KHP + NaOH → KNaP + H₂O
<em>Where 1 mole of KHP reacts per mole of KNaP</em>
<em />
That means, the moles of KHP added to the NaOH solution = Moles NaOH at equivalence point. With the moles of NaOH and the volume in liters we can find the molar concentration of NaOH.
<em>Assuming the volume added of KHP was 25.50mL and the solution of NaOH contains 30.0mL (0.0300L), the concentration of the NaOH is:</em>
<em />
<em>Moles KHP = Moles NaOH:</em>
25.50mL = 0.02550L * (0.500mol / L) = 0.01275 moles KHP = Moles NaOH
<em>Molarity NaOH:</em>
0.01275 moles NaOH / 0.0300L =
<h3>0.425M NaOH assuming the volume of KHP was 25.50mL and the volume of the NaOH solution was 30.0mL</h3>
Electric current is when electrons start to flow around a circuit. We use an ammeter to measure it and it is measured in amps
Potential difference (also called voltage) is how big the push on the electrons is. We use a voltmeter to measure it and it is measured in volts.
Resistance is anything that resists an electric current. It is measured in ohms”.
(Words: volts, amps, ohms, voltage, ammeter, voltmeter).
Do you mean semi-aqueous gypsum calcium?
Is called a semi-aqueous gypsum calcium sulfate, as the formula: CaSO4 * 1/2 H 2 O molecule of water is half (hemihydrate), contains sulfur (sulfate), and calcium (Ca).
Gypsum is a common name because it is used in construction.
Answer:
Ozone layer depletion is the thinning of the ozone layer present in the upper atmosphere. This happens when the chlorine and bromine atoms in the atmosphere come in contact with ozone and destroy the ozone molecules. One chlorine can destroy 100,000 molecules of ozone. It is destroyed more quickly than it is created
