Why is atp an example of chemical potential energy?

1 answer:

7 0

Hello! I hope this helps

Answer: ATP ( adenosine triphosphate) is considered as the energy currency of the cell as it stores energy in the cell. It is an example of chemical potential energy because energy is stored in the high energy containing phosphoanhydride bond (between phosphate molecules in the ATP).

What is the main function of the part labeled Yin the model?

NARA [144]

Answer:

The part labelled Y is the chloroplast and its main function is to produce food for the plant in the reactions of photosynthesis.

Explanation:

Plants are autotrophic organisms in that they are able to manufacture their own food. Plants are able to manufacture their own food due to the presence of the cell organelle known as the chloroplast. The plant chloroplast has its own DNA and can reproduce independently, from the rest of the cell. They can as well produce amino acids and lipids required for the chloroplast membrane.

Chloroplasts are green-colored membrane-bound organelles found within the plant cell. Their green color is due to the presence of the pigment, chlorophyll. Chlorophyll in the chloroplasts are responsible for absorbing light energy from sunlight and using this absorbed energy to make simple sugars (carbohydrates) from carbon (iv) oxide and water. This is the main function of the chloroplasts in plant cells.

Photosynthesis occurs in the chloroplasts in two reaction steps:

1. The light reaction - involves the splitting of e=water molecules using the energy of sunlight

2. The dark reactions - carbon (iv) oxide from the air is used to produce sugars.

How many grams of Pb are contained in a mixture of 0.135 kg each of PbCl(OH) and Pb2Cl2CO3?

Dahasolnce [82]

Hey there!:

Given the mass of PbCl(OH) :

0.135 Kg = 0.135 Kg*(1000g / 1Kg) = 135 g

Molecular mass of PbCl(OH) = 207+35.5+16+1 = 259.5 g / mol

Atomic mass of Pb = 207 g/mol

Hence mass of Pb in 135 g PbCl(OH) :

(207 g Pb / 259.5 g PbClOH) * 135g PbClOH =

0.79768 * 135 => 107.68 g of Pb

For Pb2Cl2CO3 :

Given the mass of Pb2Cl2CO3 :

0.135 Kg = 0.135 Kgx(1000g / 1Kg) = 135 g

Molecular mass of Pb2Cl2CO3 = 2*207+2*35.5+12+3*16 = 545 g / mol

Mass of Pb present in 1 mol (=545 g / mol) of Pb2Cl2CO3 = 2*207 = 414 g

Hence mass of Pb in 135 g Pb2Cl2CO3:

(414 g Pb / 545 g PbClOH) * 135g PbClOH =

0.75963 * 135 => 102.55 g of Pb2Cl2CO3

Hope that helps!
