Answer:
Where does the exchange of the blood in the veins and oxygen in the lungs take place?
ALVEOLI are the very small air sacs where the exchange of oxygen and carbon dioxide takes place. CAPILLARIES are blood vessels in the walls of the alveoli. Blood passes through the capillaries, entering through your PULMONARY ARTERY and leaving via your PULMONARY VEIN
Explanation:
A. Since you are starting with equal moles of the two reactants, you can see from the balanced equation that you need 3 moles of H2SO4 for every 2 moles of Al(OH)3. So, H2SO4 is the limiting reactant.
B. 0.420 mol H2SO4 X (1 mol Al2(SO4)3 / 3 mol H2SO4) = 0.140 mol Al2(SO4)3
C. Moles of Al(OH)3 used:
0.420 mol H2SO4 X (2 mol Al(OH)3/3 mol H2SO4)
= 0.280 mol Al(OH)3 used Moles remaining
= 0.420 - 0.280
= 0.140 mol Al(OH)3 remaining.
Answer:
ions are deflected and the lighter the ions the more the deflection.
Placing magnetic field in the path of the ions cause them to move in a curved path.
Explanation:
This question is all about the way in which mass spectroscopy works. Mass spectroscopy Is one of the techniques in spectroscopy which is used in the identification of chemical compounds.
Mass spectroscopy works based on the principle of ionization. For a mass spectroscopy to start ionization must first occur that is to say this is the first step in the identification of compound in mass spectroscopy.
The following steps are involve in mass spectroscopy;
=> Ionization: the molecules of the sample are first ionized. The ions formed here are positive ions.
=> Acceleration: the ions in step one are accelerated.
=> Deflection: the smaller ions get deflected more than the bigger ions. The magnetic field is used in the deflection of this ions.
=> Detection: the ions are then detected.
Therefore, to answer the question, the ions are deflected and the lighter the ions the more the deflection.
Placing magnetic field in the path of the ions cause them to move in a curved path.
Answer:
Direction
Explanation:
A weather vane is a weather instrument that is used to measure the direction the wind is blowing in.
