Why is there more co2 in the air that you breathe out than in the air that you inhale?
larisa [96]
CO2 is produced during respiration by mitochondria.
To know why there is more CO2 in the air that you breathe out than the CO2 which you inhale, we have to know that the carbon which we breathe out as carbon dioxide comes from the waste products (the carbon in the food we eat) like the carbohydrates, fat, and protein which converted in the body by biochemical pathways to glucose. the end products of oxidation of glucose are water and carbon dioxide. This carbon dioxide which dissolved in the human blood is carried to the air in the lung by circulation before it exhales.

IgorLugansk [536]

Answer:

The answer to your question is Mercury

Explanation:

The flame test essay is used to identify the identity of a substance because most elements show different colors when in flame.

There are many elements that burn violet when in flame especially elements of the group IA like Potassium, Rubidium, Cesium and also Cyanide and Mercury located in different groups.

But the bibliography tells us that Mercury chloride burns violet so this element is the correct answer because there is chloride in the sample of this question.

How many moles of H2 can be made from complete reaction of 3.0 moles of Al?
tresset_1 [31]

Answer: 4.5 moles of H_{2} can be made from complete reaction of 3.0 moles of Al.

Explanation:

The given reaction equation is as follows.

2Al + 6HCl \rightarrow 2AlCl_{3} + 3H_{2}

This shows that 2 moles of Al reacts with 6 moles of HCl. So, the amount of HCl required to react with 1 mole Al is three times the amount of HCl.

Therefore, 3 moles of Al will react with 9 moles of HCl to give 3 moles of AlCl_{3} and \frac{9}{2} moles of H_{2}.

The reaction equation now will be as follows.

3Al + 9HCl \rightarrow 3AlCl_{3} + \frac{9}{2}H_{2}

The moles \frac{9}{2} can also be written as 4.5 moles.

Thus, we can conclude that 4.5 moles of H_{2} can be made from complete reaction of 3.0 moles of Al.

Fill in the blank with the correct answer. The longer the handle the __________ the mechanical advantage and the greater the inc
ASHA 777 [7]

Answer:

Greater

Explanation:

The longer the handle, the greater the mechanical advantage and the greater the increase in force that is applied to the bolt.

Mechanical advantage is the rate at which force is multiplied.

  • It simply compares the output force to the input force.
  • M.A is the force increasing tendency of a tool.
  • The longer  the handle, the more the mechanical advantage and the lesser the applied force.
