In the electrolysis of water, how long will it take to produce 115.0 L of H2 at 1.0 atm and 273 K using an electrolytic cell through which the current is 121.0 mA

Answers

Answer 1

It will take 2273 h.

Here, the ideal gas equation is used.

What is the ideal gas law?

According to the ideal gas law, a gas's pressure is directly proportional to its volume and temperature.

[tex]PV = nRT\\[/tex]

where,

P = Pressure

V = Volume

n = No. of moles

R = Ideal gas constant

T = Temperature

Given,

V = 115.0 L

P = 1 atm

T = 273 K

I = 121 mA

R = 0.0821 atm. L/mol.K

Put the values in the above formula

[tex]n = \frac{PV}{RT}[/tex]                            

  [tex]= \frac{1(115)}{(0.0821) (273)}[/tex]

  [tex]= 5.13 mol[/tex]

The equation says,

2H⁺ + 2e⁻ → H₂

no. of electrons = 2

1 mol of the electron produces a 96500 C charge

5.13 mol of electrons will give = 5.13 × 2 × 96500

                                                  = 990,090 C

I = 121 mA = 0.121 C/s    (1mA = 0.001 C/s)

We know,

q = It

where,

q = charge

I = current

t = time

t = q/I

t = 990,090/ 0.121

t = 8182562 s

t = 2273 h

Therefore, it will take 2273 h.

Why do you think it's important for scientists to study plate tectonics? Explain.

Answers

Scientists are helping to improve understanding of how rocks in Earth's hot, deep interior enable the motions of tectonic plates, which regulate the water cycle that is critical for a habitable planet.

Studying plate tectonics is important because it helps explain Earth's surface features, predict natural disasters, investigate Earth's history, explore natural resources, and understand global climate patterns. It is a multidisciplinary field that provides valuable insights into the dynamic nature of our planet.

Scientists study plate tectonics for several important reasons. Firstly, understanding plate tectonics helps scientists explain the formation of different features on Earth's surface, such as mountains, valleys, and ocean basins. By studying the movement and interactions of Earth's tectonic plates, scientists can better understand the processes that shape our planet.

Secondly, studying plate tectonics is crucial for predicting and understanding natural disasters. Earthquakes, volcanic eruptions, and tsunamis are all related to tectonic activity. By analyzing plate boundaries and identifying areas prone to seismic activity, scientists can provide early warnings and help communities prepare for potential disasters.

Furthermore, studying plate tectonics is essential for investigating Earth's history. The movement of tectonic plates over millions of years has shaped the continents and influenced the evolution of life on our planet. By examining the distribution of fossils and rock formations, scientists can reconstruct past tectonic events and gain insights into Earth's geological history.

Additionally, understanding plate tectonics is crucial for exploring natural resources. Many valuable minerals and energy resources are formed as a result of tectonic processes. By studying plate boundaries and their associated geological features, scientists can identify potential locations for mining and resource extraction.

Lastly, studying plate tectonics contributes to our understanding of global climate patterns. The movement of tectonic plates affects ocean currents, weather patterns, and the distribution of landmasses. By analyzing these interactions, scientists can better predict and understand climate change.

Are the members of the third generation still carriers/affected by the trait? How many
percent are affected by the trait?​

Answers

Answer:

When a genetic disorder is diagnosed in a family, family members often want to know the likelihood that they or their children will develop the condition. This can be difficult to predict in some cases because many factors influence a person's chances of developing a genetic condition. One important factor is how the condition is inherited. For example:

Autosomal dominant inheritance: A person affected by an autosomal dominant disorder has a 50 percent chance of passing the mutated gene to each child. The chance that a child will not inherit the mutated gene is also 50 percent. However, in some cases an autosomal dominant disorder results from a new (de novo) mutation that occurs during the formation of egg or sperm cells or early in embryonic development. In these cases, the child's parents are unaffected, but the child may pass on the condition to his or her own children.

Can someone help me understand interphase, prophase, metaphase, anaphase, and telophase

Answers

Answer:

They are all stages of mitosis, which is cell division (for new cells for repair and growth)

interphase- the longest stage of the process. The DNA in the chromosomes copies itself, ready to split for mitosis. ALL 23 pairs copies itself so now there is 46 pairs of chromosomes (23 for each new cell).

prophase- The DNA in the chromosomes are more visible now, and the membrane around the nucleus disappears ready for the next stage

metaphase- Chromosomes and their copies line up in the middle of the cell, so that they could be pulled apart in the next stage

anaphase- Spindle fibres attach themselves to either end of the chromosome. They are then pulled apart to either ends of the cell. 23 on one side, 23 on another.

telophase- membranes form around the 23 pairs of chromosomes at their end of the cell. Two new daughter cells are produced. The cell membrane pinches in and divides the cells in two.
