Just construct the chemical equation.Knowing that a molecule of ethanol has 2 carbon atoms, 2 molecules of carbon dioxide are produced.So the mol ratio of ethanol and CO2 is 1:2 ,so 10 mols of CO2 is produced.Of course this is under the assumption that it is burnt completely.If It is not burnt completely then thats a different story.
Answer:
shivering
hair on the body standing up
goosebump forming
Explanation:
The processes that help the body warm-up from the available options include <em>the shivering of the body</em>, <em>formation of goosebumps on the skin</em>, and <em>the standing up of hairs on the body.</em>
When the temperature of the body falls below the setpoint or the environment is cold, a homeostatic response is triggered and a signal is sent from the control center to the muscles of the body. <u>The muscles start shaking in order to generate heat to raise the temperature of the body</u>. At the same time, <u>the tiny muscles at the base of the hairs on the skin contract and pull the hairs erect, causing goosebumps in the process.</u>
False , I hope this helps
M(NaCl)=1.0 g
w=0.035
p=1.02 g/mL
v-?
m(NaCl)=mw
m=vp
m(NaCl)=vpw
v=m(NaCl)/(pw)
v=1.0/(1.02·0.035)=28.0 mL
