Answer:
-195.8 °C = 77.35 K = -320.44 °F
Explanation:
Temperature is commonly measured in following three scales;
1) Kelvin
2) Fahrenheit<span>
3) </span>Celsius<span>
Other scales are Rankine, Romer, Newton, Delisle e.t.c
Temperature given is -195.8 </span>°C. Degree Celsius is related to Kelvin and Fahrenheit as follow,
Celcius to Kelvin;
K = °C + 273.15
So,
K = -195.8 + 273.15
K = 77.35
Celcius to Fahrenheit;
°F = °C × 9/5 + 32
So,
°F = -195.8 × 9/5 + 32
°F = -320.44
Yes mitochondria does make necrssary chemicals for the cell therefore the answer to your question is yes
Answer:
4380 mmHg
Explanation:
Boyle's Law can be used to explain the relationship between pressure and volume of an ideal gas. The pressure is inversely related to volume, so if volume decrease the pressure will increase. It can be expressed in the equation as:
P1V1=P2V2
In this question, the first condition is 2L volume and 876 mmHg pressure. Then the system changed into the second condition where the volume is 400ml and the pressure is unknown. The pressure will be:
P1V1= P2V2
876 mmHg * 2L = P2 * 400ml /(1000ml/L)
P2= 876 mmHg * 2L / 0.4L
P2= 4380 mmHg
Answer:
HOAc is stronger acid than HClO
ClO⁻ is stronger conjugate base than OAc⁻
Kb(OAc⁻) = 5.5 x 10⁻¹⁰
Kb(ClO⁻) = 3.3 x 10⁻⁷
Explanation:
Assume 0.10M HOAc => H⁺ + OAc⁻ with Ka = 1.8 x 10⁻⁵
=> [H⁺] = √Ka·[Acid] =√(1.8 x 10⁻⁵)(0.10) M = 1.3 x 10⁻³M H⁺
Assume 0.10M HClO => H⁺ + ClO⁻ with Ka = 3 x 10⁻⁸
=> [H⁺] = √(3 x 10⁻⁸)(0.10)M = 5.47 x 10⁻⁵M H⁺
HOAc delivers more H⁺ than HClO and is more acidic.
Kb = Kw/Ka, Kw = 1 x 10⁻¹⁴
Kb(OAc⁻) = 5.5 x 10⁻¹⁰
Kb(ClO⁻) = 3.3 x 10⁻⁷
