What is the chemical equation of photosynthesis

Chemistry
2 answers:
Fynjy0 [20]3 years ago
8 0
A simple word equation is carbon dioxide + water —> glucose + oxygen + water
A balanced chemical equation for the process can be 6CO2 + 6H2O —> C6H12O6 + 6O2. Overall, photosynthesis uses light energy to convert carbon dioxide into a carbohydrate.
Hope this helps!

carbon dioxide + electron donor + light energy ==> carbohydrate + oxidized electron donor + water

CO2 + 2H2A + photons ==> [CH2O] + 2A +  H2O

Of the colors on the visible light spectrum, which one has the longest wavelength, lowest frequency, and lowest energy?
Elenna [48]

Answer:

Red

Explanation:

Violet - shortest wavelength, around 400-420 nanometers with highest frequency. They carry the most energy.

Indigo - 420 - 440 nm

Blue - 440 - 490 nm

Green - 490 - 570 nm

Yellow - 570 - 585 nm

Orange - 585 - 620 nm

Red - longest wavelength, at around 620 - 780 nanometers with lowest frequency and least amount of energy

Therefore, <em>red </em>is the answer you're looking for.

I hope this helps and that you have a great day! :)

How many moles of Cl2 will produce 0.35 miles of NaCl when reacted with excess Na?
weeeeeb [17]
This question is based in mole ratios. for every mole of cl2, 2 moles of NaCl will be produced. so half of the moles of NaCl gives the moles of Cl2 required. therefore divide 0.35 by 2

The blank is the accepted form of gathering and reporting information within the science community.
Charra [1.4K]

Answer:

Scientific method.

Explanation:

Scientific method is the way taken to acquire scientific knowledge. It includes experiments, statistical analysis of existing data, and all kinds of observations of the world around us, while theoretical research is based on deriving certain theories about the world from basic principles, in a mathematical or logical way. The scientific method applies to both types of research, and emphasizes that scientific research is objective, that it can be verified by other scientists, and that knowledge is not acquired without context, but in a way that leads to a greater understanding of previous research and the world. we live in. To contribute to this, researchers are expected to clearly record both their findings and the methods they use to arrive at the results.

Determine the number of significant figures in the measurement quantity: 2600. kg.
xxMikexx [17]

Answer:

2600 kg has 4 significant figures

Explanation:

Any different number to zero is a significant figure

For example, 1.8 → 2 significant figures

When you  have 0 in the middle of two numbers, we consider it as a significant number

For example, 3.02 → 3 significant figures

When you have 0 on the left in the measure, we do not consider as a sgnificant figures

For example 0.0010 → 2 significant figures (10)

3.0 → 2 significant figures (0 is on the right, not the left)

Suppose you have 81.8 g of Cd. How many Cd atoms are present? Report your answer in scientific notation using the format of 6.02
Lostsunrise [7]

Answer:

1. number of Cd atoms = 4.384 × 10²³

2. number of moles of Ti = 0.817 mol

3. molar mass of C₇H₆O₃ = 138.077 g/mol

4. moles of Sildenafil = 0.249 mmol

Explanation:

1. given data

mass of Cd = 81.8 g

number of Cd atoms = ?

molar mass of Cd = 112.411 g/mol

Solution

1st we find out the number of moles of Cd

<em>         number of moles = mass / molar mass </em>

 number of moles of Cd = 81.8 g / 112.411 g.mol⁻

 number of moles of Cd = 0.728 mol

Now we find out the number of Cd atoms

<em>       number of atoms = moles × 6.022 × 10²³</em>

 number of Cd atoms = 0.728 (6.022 × 10²³)

 number of Cd atoms = 4.384 × 10²³

 

2. Given data

Mass of Ti = 39.1 g

moles = ?

molar mass Ti = 47.867 g/mol

Solution

Now we will find out the number of moles

<em>         number of moles = mass / molar mass </em>

 number of moles of Ti = 39.1 g / 47.867 g.mol⁻

 number of moles of Ti = 0.817 mol

3. Given data

chemical formula of Salicylic acid  = C₇H₆O₃

molar mass of salicylic acid = ?

molar mass of carbon = 12.011

molar mass of hydrogen = 1.008

molar mass of oxygen = 15.999

<em>         molar mass of  molecule = number of moles of atoms × molar mass of atoms</em>

  molar mass of C₇H₆O₃ = 7 (12.011) + 6 (1) + 3 (16)

  molar mass of C₇H₆O₃ = 84.077 g + 6 g + 48 g

  molar mass of C₇H₆O₃ = 138.077 g/mol

4. Given data

molar mass of Sildenafil = 474.5828 g/mol

mass given = 0.118 g

moles of Sildenafil = ?

Solution

Now we find out the number of moles

<em>          number of moles = mass / molar mass </em>

<em>   </em>number of moles Sildenafil = 0.118 g / 474.5828 g/mol

  number of moles Sildenafil = 0.0003 mol

as this is very small amount we convert it into millimoles

           <em>millimoles = moles × 1000</em>

    millimoles of Sildenafil = 0.000249 × 1000

    millimoles of Sildenafil = 0.249 mmol
