The adrenal gland respond to stress that is experienced in your body. These are produced within the medulla. The cortisol helps regulate your metabolism, sugar levels and blood pressure. The adrenal glands are controlled by the pituitary gland.
Answer : The percent yield of is, 68.4 %
Solution : Given,
Mass of = 0.16 g
Mass of = 0.84 g
Molar mass of = 16 g/mole
Molar mass of = 32 g/mole
Molar mass of = 44 g/mole
First we have to calculate the moles of and .
Now we have to calculate the limiting and excess reagent.
The balanced chemical reaction is,
From the balanced reaction we conclude that
As, 2 mole of react with 1 mole of
So, 0.026 moles of react with moles of
From this we conclude that, is an excess reagent because the given moles are greater than the required moles and is a limiting reagent and it limits the formation of product.
Now we have to calculate the moles of
From the reaction, we conclude that
As, 2 mole of react to give 1 mole of
So, 0.026 moles of react to give moles of
Now we have to calculate the mass of
Theoretical yield of = 0.572 g
Experimental yield of = 0.391 g
Now we have to calculate the percent yield of
Therefore, the percent yield of is, 68.4 %
= Once connected, a duplex system allows you to talk to the other person at the same time.
= You dial a number on your cell phone.
The MTSO then connects you to the other device.
= A base station contacts the Mobile Telephone Switching Office (MTSO).
Answer:
You dial a number on your phone
Your phone contacts a base station
The base station contacts the MTSO
The MTSO connects you to the other device
You talk to the person on the other device.
b. 0.1%
c. 1%
d. 10%
Answer:
a) 0.01 %
Explanation:
The carbon in the atmosphere is mainly in the form of carbon dioxide (CO2).
The ammount of carbon is arround 700 gigatons and they represent the 0.01 % of the carbon on Earth.
