Green plants absorb sunlight to power photosynthesis, the chemical synthesis of food from water and carbon dioxide. The compound
Kamila [148]

Answer:

698 \ THz

Explanation:

Data provided as per the question below:-

Wavelength = 430.nm

The computation of the frequency of the light is shown below:-

Frequency = Velocity of light ÷ Wavelength

The  Velocity of light = = {3.0 \times 10^8 \ m/s}

Wavelength = 430 nm = 4.30 \times 10^-^7 m

Frequency = \frac{3.0 \times 10^8 \ m/s}{4.30 \times 10^-^7}

= 6.98 \times 10^1^4 \ hz

= 6.98 \times 10^2 \ Thz

= 698 \ THz

Therefore for determining the frequency we simply applied the above formula.

If you heat the cup of soup in the microwave to make it boil. Will it have a higher total kinetic energy than the bowl of soup?
Paha777 [63]

No, The kinetic energy depends upon the number of particles motion. The hot bowl of soup will have greater number of particles in motion and it will contain more kinetic energy than the cup of soup.

steposvetlana [31]

Answer:

The mass of coke needed to react completely with 1.0 ton of copper(II) oxide is 0.794 Ton.

Explanation:

2CuO+C\rightarrow 2Cu+CO_2

1 Ton = 907185 grams

Mass of copper oxide = 1.0 Ton = 907185 grams

Moles of copper oxide =\frac{907185 g}{79.55 g/mol}=11,403.95 moles

According to reaction, 2 moles of copper oxide reacts with 1 mole of carbon.

Then 11403.95 moles of copper oxide will react with:

\frac{1}{2}\times 11403.95 mol=5,701.98 mol of carbon

Mass of 5,701.98 moles of carbon:

5,701.98 mol\times 12 g/mol=68,423.75 g

Mass of coke = x

Mass of carbon = 68,423.75 g

Percentage of carbon in coke = 95%

95\%=\frac{68,423.75 g}{x}\times 100

x=720,250.09 g=0.794 Ton

The mass of coke needed to react completely with 1.0 ton of copper(II) oxide is 0.794 Ton.
