Does Kumiho the legendary exist??​

Answers

Answer: Deriving from ancient Chinese myths and folklores, a fox that lives a thousand years turns into a kumiho, like its Japanese and Chinese counterparts. It can freely transform, among other things, into a beautiful woman often set out to seduce boys, and eat their liver or heart (depending on the legend).

Hoped that helped!

Answer:

No

Explanation:

The Kumiho is similar to other fox creatures, such as the Japanese kitsune and Chinese Huli jing. Even though they have similar magical abilities and longevity, Kumiho is more malevolent than other fox spirits. Of these long-lived legendary creatures, the Kumiho is the only fox that kills and eats humans. Kumiho is just a myth itś not real and no one has seen this fox so "it" does not exist.

The head of a pin is 1.5 × 10-3 m in diameter. If 1.136 × 107 atoms of oxygen can fit across the head of a pin, what is the atomic radius of oxygen?

Answers

About five million million hydrogen atoms could fit. Some factors would affect that number like the area of the head and the size of atoms (as well as attractions between atoms). Some atoms are larger than others.

If 1.136 × 10⁷ atoms of oxygen can fit across the head of a pin whose diameter is 1.5 × 10⁻³ m, the atomic radius of oxygen would be 6.60 × 10⁻¹¹ m.

The head of a pin is 1.5 × 10⁻³ m in diameter. If 1.136 × 10⁷ atoms of oxygen can fit across the head of a pin, the diameter of each oxygen atom would be:

[tex]\frac{1.5 \times 10^{-3}m }{1.136 \times 10^{7}atom} = 1.32 \times 10^{-10}m/atom[/tex]

The atomic radius of oxygen would be half of its diameter.

[tex]\frac{1.32 \times 10^{-10} m}{2} = 6.60 \times 10^{-11} m[/tex]

If 1.136 × 10⁷ atoms of oxygen can fit across the head of a pin whose diameter is 1.5 × 10⁻³ m, the atomic radius of oxygen would be 6.60 × 10⁻¹¹ m.

Explanation:

To give a visual display of measurement precision best specifies the purpose of error bars on a graph.

What are errors?

Errors in chemical analysis result when there is a difference between observed value and the true value.If the magnitude of errors is large , it results in decrease in accuracy, reproducibility, and precision.

There are three types of errors:1) random error 2) systematic error 3) human error.The cause of random errors are difficult to quantify while the human errors can be minimized by taking a range of readings to reduce the error.

Errors while measuring boiling point may be human errors while noting down the boiling temperature or instrumental or systematic error if there is a fault in the thermometer.The experiments must be done with utmost care to minimize the range of errors.

Some chemical reactants are listed in the table below. Complete the table by filling in the oxidation state of the highlighted atom.

Answers

Answer:

1. Cu = +2

2. O = – 2

3. C = +2

4. N = 0

Explanation:

Note:

A. The oxidation state of oxygen is always – 2 except in peroxides where it is – 1.

B. The oxidation state of Hydrogen is always +1 except in metallic hydrides where it is – 1.

Now let us solve the question given above.

1. CuO = 0 (ground state)

Cu + O = 0

O = – 2

Cu + (– 2) = 0

Cu – 2 = 0

Collect like terms

Cu = 0 + 2

Cu = +2

2. H2O = 0 (ground state)

2H + O = 0

H = +1

2(1) + O = 0

2 + O = 0

Collect like terms

O = 0 – 2

O = – 2

3. CO = 0 (ground state)

C + O = 0

O = – 2

C + (– 2) = 0

C – 2 = 0

Collect like terms

C = 0 + 2

C = +2

4. N2 = 0 (ground state)

2N = 0

Divide both side by 2

N = 0/2

N = 0

What is the percentage by mass of a solution with 30.0g salt dissolved in water to make 650.0g 0f solution?
Please help​

Answers

Answer:

The percentage by mass of a solution with 30.0g salt dissolved in water to make 650.0g 0f solution is 4.61 %

Explanation:

The mass percentage of a solution is a measure of concentration that indicates the number of grams of solute that there are per 100 grams of solution.

The percent by mass is calculated as the mass of a component divided by the total mass of the mixture, multiplied by 100 to give a percentage.

[tex]percentage by mass=\frac{solute mass}{solution mass} *100[/tex]

In this case:

solute mass: 30 gsolution mass: 650 g

Replacing in the definition of percent by mass:

[tex]percentage by mass=\frac{30 g}{650 g} *100[/tex]

Solving:

percent by mass= 4.61 %

The percentage by mass of a solution with 30.0g salt dissolved in water to make 650.0g 0f solution is 4.61 %

HELP 100 POINTS explain how you would separate the components of a dirty water mixture that consists of: • coffee grounds • garlic powder • vegetable oil • sodium chloride (table salt) • gravel and sand • water. For each step discuss what separation method you are using and why you chose that method​

Answers

Note that all detail explanation on why or how will be attached at the end

Step 1: Removing the Oil

Theoretically, step 1 and 2 can be alternated and preferably I would start with step 2, but I thought of one first. I would begin by setting up the liquid mixture in a funnel with a closed twist valve. Once the water mixture and oil has separated, I would slowly remove all the water, leaving the oil.

Step 2: Removing the Gravel and Sand

The second step is to filter out solids by using a sand filter. This filter is made by using a Styrofoam cup that has had small holes punched into the bottom with an open paperclip. The cup is filled with layers of clean washed gravel. The gravel will be layered by putting course gravel in the bottom and fine sand in the middle followed by course sand on the top. The gravel on the bottom stops the loss of sand out of the holes and the gravel on top stops the sand from washing out as a sample is poured.

Step 3: Removing the Coffee Grounds and Garlic Powder

You would start by lining a clean funnel with a coffee filter or something comparable. Then, you would add a spoonful or so of Charcoal to the funnel. Then you would pour the mixture of water, garlic powder, salt and coffee grounds into it.

Step 4: Removing Salt

You would preform a simple evaporation to remove the salt from the water. If the water is still needed, then you can preform a sealed distillation which has the same effect, but just keeps the water.

Step 5: Celebrate!

If you are doing this is a school, congratulations! you just finished your assignment/lab! If you are doing this in the wilderness for survival, congratulations! you won't die so soon!*

*The purification of water will not guarantee your extended survival in the wilderness, just extend the time in which you will not die of dehydration.™

Explanation:

Step 1 works because the density of oil and water are different, so as you let the liquid settle, the two liquids will separate into two sections. This allows you to funnel the water out. Step 2 work because the gravel and sand you want out cannot pass the sand-gravel filter you made (as long as it was made correctly) Step 3 works because the garlic powder and coffee grounds cannot pass the filter and the smell and colour that leaked into the water would be removed by the charcoal. Step 4 works because as water evaporates or is boiled off, the salt cannot evaporate with it, so it is left behind. Like how I was in the mall. Step 5 works because this was a long explanation and now you can go look at memes.


A sample of seawater weighs 250 g and has a volume of 173 ml. What is the density of seawater?

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} \\ [/tex]

From the question

mass of seawater = 250 g

volume = 173 mL

It's density is

[tex]density = \frac{250}{173} \\ = 1.4450867052...[/tex]
