<u>Answer:</u>

Mass of C in 3.40 g of HCN =1.51 gram.

<u>Explanation:</u>

  Mass of sample of HCN = 7.99 g

  Mass of H in 7.99 g of HCN = 0.296 g

  Mass of N in 7.99 g of HCN = 4.14 g

  Mass of C in 7.99 g of HCN = (7.99-0.296-4.14) = 3.554 g

  Now mass of HCN = 3.40 g

  Mass of C in 3.40 g of HCN = \frac{3.554}{7.99} *3.40 =1.51 g

 So mass of C in 3.40 g of HCN =1.51 gram.

If the charge on the negative plate of the capacitor is 121 nano-Coulomb, how many excess electrons are on that plate? Write you
Julli [10]

Answer:

n = 756.25 giga electrons

Explanation:

It is given that,

If the charge on the negative plate of the capacitor, Q=121\ nC=121\times 10^{-9}\ C

Let n is the number of excess electrons are on that plate. Using the quantization of charges, the total charge on the negative plate is given by :

Q=ne

e is the charge on electron

n=\dfrac{Q}{e}

n=\dfrac{121\times 10^{-9}}{1.6\times 10^{-19}}

n=7.5625\times 10^{11}

or

n = 756.25 giga electrons

So, there are 756.25 giga electrons are on the plate. Hence, this is the required solution.

Using the criteria you described in your previous answer, how would you compare solar power to fossil fuel power?
Scilla [17]

Solar power differ to fossil fuel power in that solar power is a much more optimal resource than fossil fuels

  • Solar power; however provides much more energy than fossil fuel power
  • Interestingly too, solar power resource can be used without releasing greenhouse gases compared to fossil fuels power
  • Infact, solar energy is the most reliable

<h3>What is renewable energy?</h3>

Renewable energy simply refers to energy that is not depleted when used. An example of such is solar power.

So therefore, solar power differ to fossil fuel power in that solar power is a much more optimal resource than fossil fuels

Why don’t trade winds blow straight toward the equator<br> Apex
rosijanka [135]

Trade winds near equator blows in curve path instead of straight path. This is because of earth rotation. This effect of earth rotation that cause wind to move in curve motion is called Coriolis effect. These kind of wind blows at the northeast of the North hemisphere and southeast of the South hemisphere. The trade wind are warm and it blows due to rising of hot air from equator.
