Can the Ed-You-Swivel chairs capture enough energy to power the school's small electronics

Chemistry
1 answer:
Katen [24]3 years ago
3 0

Answer: The Ed- you swirl chair could not produce energy to power the school electronics.

Explanation:

The data obtained from the electric company demonstrates that the school uses the 15 million joules of energy per hour. The energy produced by the chair will not provide the enough labor that the school uses. This was proved by the engineers product testing lab, Inc.. They proved that the chair could harness 4,000 joules of energy in a day for use. It takes 20 days to the chair to charge one tablet which is time consuming and labor done by the chair will get compromised. This shows that the chair will be cover even of fraction of energy required for school use to charge the small electronics.

bekas [8.4K]

Answer:

Option D. 3, 1, 3, 1

Explanation:

From the question given above,

HNO₃ + Al(OH)₃ —> HOH + Al(NO₃)₃

The equation can be balance as follow:

HNO₃ + Al(OH)₃ —> HOH + Al(NO₃)₃

There are 3 atoms of N on the right side and 1 atom on the left side. It can be balance by 3 in front of HNO₃ as shown below:

3HNO₃ + Al(OH)₃ —> HOH + Al(NO₃)₃

There are a total of 6 atoms of H on the left side and 2 atoms on the right side. It can be balance by 3 in front of HOH as shown below:

3HNO₃ + Al(OH)₃ —> 3HOH + Al(NO₃)₃

Now, the equation is balanced.

Thus, the coefficients are 3, 1, 3, 1

natita [175]

Answer:

Since one banknote has a thickness of about 0.1 millimeters, if all the banknotes produced in a year were stacked up, they would reach a height of approximately 300 kilometers, which is about 80 times the height of Mount Fuji.

Good morning, I have a question..
matrenka [14]

Answer:

<h3>The answer is 5.24 mL</h3>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

volume =  \frac{mass}{density} \\

From the question

mass = 152 g

density = 29 g/cm³

We have

volume =  \frac{152}{29}  \\  = 5.24137931...

We have the final answer as

<h3>5.24 mL</h3>

Hope this helps you
