Andrei [34K]3 years ago
4 0

B). light energy is not required to proceed

Explanation:

In the Calvin cycle of photosynthesis, light energy is not required. The Calvin cycle is light independent and it is made up of a series of redox reactions.

  • During photosynthesis reactions, green plants manufacture their food using carbon dioxide, sunlight and water.
  • During the Calvin cycle aspect, light energy is not required for chemical reactions to take place. The light energy helps to move electrons.
  • The cycle is also known as dark reactions.
  • It is at this stage that carbon dioxide combines with water to form glucose.
  • The reaction is initiated with light energy which produces NADPH and ATP.
  • The Calvin cycle follows by using the NADPH and ATP to produce glucose in the dark phase.

Enter a balanced nuclear equation for the production of lead-212, used in the treatment of some cancers, from the beta decay of
MariettaO [177]

Answer:

\frac{212}{81}Tl ------>\beta  + \frac{212}{82}Pb

Explanation:

Beta emission involves the conversion of a neutron to a proton, an electron and a neutrino. This leads to a reduction in the neutron-proton ratio.

During a beta emission, the mass number of the parent and daughter nuclei remain the same. The atomic number of the daughter nucleus increases by one unit above that of the parent nucleus as we can see from the equation.

Hence, the daughter nucleus is found one place after its parent in the periodic table.

Why melting point of Fe in blast furnace is lower than ellingham?
Kaylis [27]

Answer:

Because they are different oxides.

Explanation:

In both processes they are involve Iron Oxides, but in the case of Ellingham diagrams, it is consider the Iron in combination with oxygen to form FeO, so the melting point is around 1600  ºC. In the case of blast furnace, the Fe that is present in the ores, are primary the hematite (Fe2O3) and the magnetite (Fe3O4).

How many particles would be found in a 1.224 g sample of K2O
lbvjy [14]

Answer:

9.96*10^21

Explanation:

Molar mass of K2O=29*2+16

= 74g per mol

number of moles in the sample= 1.224/ 74

=0.1654

Number of particles in 1 mole=6.0221409*10^23

Number of particles= 0.01654*6.0221409*10^23

=9.96*10^21
