The continuous cycling of carbon in the earyh is known as the carbon cycle.
<h3>What is the carbon cycle?</h3>
The carbon cycle is a cycle which explains the various processes by which carbon is recycled between the atmosphere and the earth.
The constant flow of carbon on earth through organisms and the air is known as the carbon cycle. Plants absorb carbon from the atmosphere in the form of carbon dioxide. They use it for respiration and food production.
Animals consume plants, transferring carbon along the food chain.
Plants and animals respire and release carbon into air. When the animals and plants die, they are eaten by decomposers.
Carbon enters back into the atmosphere in the form of carbondio dioxide.
Therefore, the continuous cycling of carbon in the earth is known as the carbon cycle.

Answer:
600 seconds, or 10 minutes
Explanation:
300m/ 0.5m = 600s
Answer:
0.0585 M
Explanation:
- Pb(NO₃)₂ (aq) + 2NaCl (aq) → PbCl₂ (s) + 2NaNO₃ (aq)
First we <u>calculate the inital number of moles of each reagent</u>, using the <em>given volumes and concentrations</em>:
- 0.255 M Pb(NO₃)₂ * 52.1 mL = 13.3 mmol Pb(NO₃)₂
- 0.415 M NaCl * 38.5 mL = 16.0 mmol NaCl
Then we <u>calculate how many Pb(NO₃)₂ moles reacted with 16.0 mmoles of NaCl</u>, using the <em>stoichiometric coefficients of the reaction</em>:
- 16.0 mmol NaCl *
= 8.00 mmol Pb(NO₃)₂
Now we <u>calculate the remaining number of Pb(NO₃)₂ moles after the reaction</u>:
- 13.3 mmol - 8.00 mmol = 5.30 mmol Pb(NO₃)₂
Finally we <em>divide the number of moles by the final volume</em> to <u>calculate the concentration</u>:
- 5.30 mmol / (52.1 mL + 38.5 mL) = 0.0585 M
Answer:
Displaced
Explanation:
A convenient way to measure the volume of an object is to measure the volume of a solid is to immerse the solid into water.
When a solid is immersed in water, it displaces some volume of water. This volume of water displaced is the same as the volume of the object.
For instance, if the volume of water in a measuring cylinder was 25 ml and i added a stone which made the water in the measuring cylinder to rise to 70 ml, it simply means that the volume of the object is 70 ml - 25 ml = 45 ml
easy there are three levels so you look at the periodic table and go to the third row now the last level on this atom is 1 electron so your answer is <u>Na</u>
