Total mass of carbon must be decreasing in different step of carbon cycle because matter is conserved in the processes and reactions of carbon cycle. Carbon is a matter and it is the major constituent of living organisms.

Carbon cycle refers to processes where carbon move from the atmosphere to the biosphere and Earth and then back to the atmosphere.

It involves processes of using and reusing carbon again and again and it's conservation.

Carbon is an organic matter found in living organisms and total mass of carbon reduces because it is a matter that is conserved.

Carbon is released from that atmosphere, use for photosynthesis, plants and animals consume the plants. They defecate , respirate and carbondioxide is released during respiration.

Therefore,Total mass of carbon must be decreasing in different step of carbon cycle because because matter is conserved in the processes and reactions of carbon cycle. Carbon is a matter and it is the major constituent of living organisms.

marta [7]

<u>Answer:</u> The mass of carbon in given amount of carvone is 47.52 grams

<u>Explanation:</u>

To calculate the number of moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}     .....(1)

Given mass of carvone = 55.4 g

Molar mass of carvone = 150.22 g/mol

Putting values in equation 1, we get:

\text{Moles of carvone}=\frac{55.4g}{150.22g/mol}=0.369mol

The chemical formula of carvone is C_{10}H_{14}O

This contains 10 moles of carbon atom, 14 moles of hydrogen atom and 1 mole  of oxygen atom

Now, calculating the mass of carbon in carvone from equation 1, we get:

Molar mass of carbon = 12 g/mol

Moles of carbon = (10 × 0.396) = 3.96 moles

Putting values in equation 1, we get:

3.96mol=\frac{\text{Mass of carbon}}{12g/mol}\\\\\text{Mass of carbon}=(3.96mol\times 12g/mol)=47.52g

Hence, the mass of carbon in given amount of carvone is 47.52 grams

 The statement  which is true  is

Fluorine  is more reactive  than nitrogen because fluorine  needs  only  one electron to fill  its  outermost  shell.


     <u><em>Explanation</em></u>

Fluorine  has  electron configuration  of 1S²2S²2P⁵  while nitrogen  has 1S²2S²2P³  electron configuration.

The 2P sub shell  for nitrogen   is  half filled  therefore it is sable  than fluorine.

since  p orbital  can hold a maximum  of  6  electrons ,Fluorine  requires  1 electron  to  completely fill  it's 2P  sub shell  which make it    more  reactive than nitrogen.

A student shines a flashlight on the lens. Which best describes what happens when light rays exit the lens?
zhannawk [14.2K]
The flashlight's beam will all be refracted towards a central axis. But, this is still dependent on the type of lens that is used for the said activity. The speed of light will vary depending whether the lens is a concave or a convex lens. The exit point of the light will always head towards the central axis.
