Answer:

Radiant energy to chemical energy

Explanation:

Got it right on edge 2021

One energy transformation that is taking place in the photosynthesis process is radiant energy to chemical energy.

Energy transformation is the process in which one form of energy converted into another form of energy.

Photosynthesis process is defined as the process in which plants makes their own food by using the carbon dioxide, water and sunlight in the chlorophyll.

The balanced chemical equation of photosynthesis process is

6CO2 + 6H2O → C6H12O6 + 6O2.

Since, it have 6 atoms of carbon, 12 atoms of hydrogen and 18 atoms of oxygen on both side. So, it is balanced.

Since, sunlight which it take is in the form of radiant and convert it into chemical energy.

Thus, we concluded that the energy transformation that is taking place in the photosynthesis process is radiant energy to chemical energy.

Answer:

31.0 g C8H18

Explanation:

Gasoline is equivalent to C8H18

to convert molecule to gram you have to convert molecules to mols first.

Using Avocado's number we can figure that out.

(1.63 x 10²³ molecules C8H18) (1 mol C8H18/ 6.022 x 10²³) = 0.271 mols C8H18

Then we convert mols to grams using the molar mass of C8H18

C - 8(12.011) = 96.088 g/mol

H - 18(1.008) = 18.144 g/mol

add that together: 114.232 g/mol

(0.271 mol C8H18) (114.232 g/ 1 mol C8H18) = 31.0 g

31.0 g C8H18

Answer:

chemical weathering occurs on the surface of minerals, the water and acids that control chemical weathering require access to the surface. Physical weathering breaks the rock to provide that surface

Answer:

78.04g of 0.448 moles must be added

Explanation:

Using H-H equation we can find the pH of the buffer:

pH = pKa + log [A⁻] / [HA]

Where pH is the pH of the buffer = 7.2

pKa = 7.1

[A⁻] = [K₂HPO₄]

[HA] = [KH₂PO₄]

Replacing:

7.2 = 7.1 + log [K₂HPO₄] / [KH₂PO₄]

0.1 = log [K₂HPO₄] / [KH₂PO₄]

1.2589 = [K₂HPO₄] / [KH₂PO₄] (1)

And as the  concentration of the buffer is:

1M = [K₂HPO₄] + [KH₂PO₄] (2)

Replacing (2) in (1):

1.2589 = 1M - [KH₂PO₄] / [KH₂PO₄]

1.2589 [KH₂PO₄] = 1M - [KH₂PO₄]

2.2589 [KH₂PO₄] = 1M

[KH₂PO₄] = 0.44M

And [K₂HPO₄] = 0.56M

In 800mL = 0.8L:

0.8L * (0.56mol / L) = 0.448 moles K₂HPO₄. The mass is -Molar mass K₂HPO₄: 174.2g/mol-:

0.448 moles * (174.2g / mol) =

Lowering the pressure in a container will cause the liquid in the container to boil faster because it becomes easier for the molecules to escape.

Boiling happens when the vapor pressure of a liquid equals the atmospheric pressure.

By lowering the atmospheric pressure, the vapor pressure of a liquid takes a lower time to equal the atmospheric pressure.

Thus, it becomes easier for the molecules of the liquid to escape from each other.

Explanation:

Water can take many forms. At low temperatures (below 0°C), it is a solid. When at “normal” temperatures (between 0°C and 100°C), it is a liquid. While at temperatures above 100°C, water is a gas (steam).

The state the water is in depends upon the temperature.  Each state (solid, liquid, and gas) has its own unique set of physical properties.

so balenced equation is 6Co+4P=2(Co3P2)

so so the ratio is 6:4

so .275/6*4

=0.183 mol I think

The Answer will be:  0.183 mol

       so that .275/6*4

      =0.183 mol.

Ionic compounds conduct electricity when molten (liquid) or in aqueous solution (dissolved in water), because their ionsare free to move from place to place. Ionic compoundscannot conduct electricity when solid, as their ions are held in fixed positions and cannot move.
