Answer:
They form a covalent bond
V1/T1 = V2/T2
V1= 3.5 L
T1 = 25 +273=298 K
T2 = 40.9 + 273 = 313.9 K
V2- ?
3.5 L/298 K= V2/ 313.9 K
V2 = (3.5 L*313.9 K)/298 K ≈ 3.69 L
Answer:
Matthias Jacob Schleiden was a German botanist who, with Theodor Schwann, cofounded the cell theory. In 1838 Schleiden defined the cell as the basic unit of plant structure, and a year later Schwann defined the cell as the basic unit of animal structure.
Explanation:
Answer:
1. Multimeter
2. Cathode
3. Capacitor
4. Selector switch
5. Short or Shorted
6. Resistors
7. Resistor color coding
8. Open Capacitor
9. Step-up transformer
10. Step-down transformer
Explanation:
The above-described elements are electronic components. Resistors for instance are designed to resist the flow of electric current. They are also standardized such that a deviation from the set resistance level will indicate a problem. The capacitor is another electrical component that stores energy as an electrical charge. Knowledge of these electrical components and the ways they are tested will make a person proficient in electrical electronics.
Answer:
The answer to your question is pH = 9.2; [OH] = 1.58 x 10⁻⁵
Explanation:
Data
[H⁺] = 6.0 x 10⁻¹⁰ M
pH = ?
pH definition. pH measures the hydrogen concentration. pH measures the acidity and the alkalinity of a solution. A solution is acid if the pH goes from 0 to 6.9, a neutral solution has a pH of 7 and an alkali solution has a pH from 7.1 to 14.
pOH measures the [OH⁻] concentration
Formula
pH = -log[H⁺]
pH + pOH = 14
-Substitution
pH = -log[6 x 10⁻¹⁰]
-Simplification
pH = - (-9.2)
pH = 9.2
-Calculate pOH
pOH = 14 - pH
pOH = 14 - 9.2
pOH = 4.8
-Calculate the concentration of OH⁻
pOH = -log[OH⁻]
[OH⁻] = -antilog4.8
[OH] = 1.58 x 10⁻⁵
