d=0,7918\frac{g}{mL}\\ V=10mL \ \ \ \ \ \ \ \ \ \ \ m=dV=0,7918\frac{g}{mL}*10mL=7,918g\\\\ 6,02*10^{23} \ \ \ \ \ \ \ \Rightarrow \ \ \ \ 32g\\ N_{x} \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \Rightarrow \ \ \ \ 7,918g\\\\ N_{x}=\frac{6,02*10^{23}*7,918g}{32g}\approx1,49*10^{23}

Select the correct answer from each drop-down menu. carbon is found in all living organisms. the constant flow of carbon on eart
Nady [450]

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.

Consider the hypothetical reaction 3A + 4B → C + 2D Over an interval of 2.50 s the average rate of change of the concentration o
faust18 [17]

Answer:

Final [B] = 1.665 M

Explanation:

3A + 4B → C + 2D

Average rection rate = 3[A]/Δt = 4[B]/Δt = [C]/Δt = 2[D]/Δt

0.05600 M/s = 4 [B]/ 2.50 s

[B] = 0.035 M (concentration of B consumed)

Final [B] = initial [B] - consumed [B]

Final [B] = 1.700 M - 0.035 M

Final [B] = 1.665 M
