<h3>Answer:</h3>

4.227 × 10^-19 Joules

<h3>Explanation:</h3>

Energy of a photon of light is calculated by the formula;

E = hf, where h is the plank's constant, 6.626 × 10^-34 J-s and f is the frequency.

But, f = c/λ

Where, c is the speed of light (2.998 × 10⁸ m/s), and λ is the wavelength.

Given the wavelength is 470 nm or 4.7 × 10^-7 m

Therefore;

E = hc/λ

= (6.626 × 10^-34 J-s × 2.998 × 10^8 m/s) ÷ 4.7 × 10^-7 m

= 4.227 × 10^-19 Joules

Therefore, the energy of a photon with 470 nm is 4.227 × 10^-19 Joules

Water combines with carbon dioxide Choose one: A. only in the atmosphere. B. to produce hydrogen sulfide. C. to precipitate calc

katovenus [111]

Water combines with carbon dioxide to produce slightly acidic groundwater

that dissolves limestone and forms caves.

This is because the reaction between water and carbondioxide to form

bicarbonate ions( HCO₃⁻). The bicarbonate ions dissociate into Hydrogen

atoms thereby increasing the acidity.

The acidic environment results in the formation of acidic groundwater that

dissolves limestone and forms caves.

The compound $C_{3}H_{4}$ will have a triple bond.

Explanation:

A compound which consists of carbon and hydrogen atoms is known as a hydrocarbon.

Alkanes, alkenes and alkynes are all hydrocarbons.

General chemical formula of an alkane is $C_{n}H_{2n+2}$ . In an alkane molecule, all the atoms will be bonded through single bonds.

For example, $C_{3}H_{8}$ is propane.

General chemical formula of an alkene is $C_{n}H_{2n}$ . An alkene molecule will have atleast one double bond between two carbon atoms.

For example, $C_{2}H_{4}$ is ethene.

General chemical formula of an alkyne is $C_{n}H_{2n-2}$ . An alkyne will have atleast one triple bond between two carbon atoms.

For example, $C_{3}H_{4}$ is propyne.

Thus, we can conclude that out of the given options $C_{3}H_{4}$ will have a triple bond.
