In a water molecule, the Oxygen has a ____________ charge and the hydrogens have a ____________ charge.

Biology
1 answer:
Contact [7]3 years ago
3 0

Answer:    A. Negative, positive

Explanation:  The water formula is known as H₂O, where according to the formula, two hydrogen atoms are bonded to one oxygen atom. The oxygen charge is -2, because it belongs to the group of atoms with valence number six. This means that oxygen has six valence electrons and it needs two more electrons to have eight and become neutral. Therefore, it has a negative charge of -2, and in the water molecule binds two hydrogen atoms, each with a charge of +1. Thus, by binding two positive hydrogen atoms, the total water molecule is stable.

A hypothesis that has been tested again and again , with similar results each time may become a law , true or false
Sever21 [200]

This statement is false.

<u>Explanation:</u>

If the results are the same, a hypothesis turns into a theory first.

A hypothesis is an assumed statement which may or may not be correct. Special experiments are designed under controlled conditions to find out whether the hypothesis is correct or not. If the Hypothesis is correct, it becomes a theory. A theory is a sophisticated explanation of the results which is further refined to make a law.

The energy acquired in photosynthesis is used to make glucose. Where is the glucose made in plants?
klio [65]

Explanation:

<u>in the stroma</u>

Photosynthesis produces glucose and O2 from inorganic CO2, light energy and water.

6CO2 + 6H20 + (energy) → C6H12O6 + 6O2

Further Explanation:

Photosynthesis is a chemical pathway that’s integral to producing energy in plants and other primary producers. Energy in the form of molecules of glucose is produced from light, water and carbon dioxide while oxygen is released. This occurs in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. This occurs in the thykaloids, where pigment molecules like chlorophyll reside.

Occuring in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. Water supplies the chlorophyll in plant cell with replacement electrons for the ones removed from photosystem II.

Additionally,

  • water (H2O) split by light during photolysis into H+ and OH- acts as a source of oxygen along with functioning as a reducing agent; it reduces the molecule NADP to NADPH by providing H+ ions and produces molecules of the energy storage molecule ATP through an electron transport chain.
  • This occurs in the thykaloids, where pigment molecules like chlorophyll reside.
  • Later, in dark reactions, NADP and NADPH are used in the Calvin cycle where monosaccharides or sugars like glucose are produced after the modification of several molecules in the stroma. These store energy in their bonds, which can be released in respiration in the mitochondria.
