The reaction is

2H₂(g)  + O₂(g) ---> 2H₂O

Thus as per balanced equation two moles of hydrogen will react with one moles of oxygen.

There is a directly relation between moles and volume. [One mole of each gas occupies 22.4 L of volume at STP]

Thus we can say that two unit volume of hydrogen will react with one unit volume of oxygen

Now as we have started with equal units of volume of both oxygen and hydrogen, half of oxygen will be consumed against complete volume of hydrogen

so the gas which will remain in excess is oxygen

State and explain the observations when chlorine gas is bubbled through a solution of
natta225 [31]

Answer:

A reduction-oxidation (redox) reaction will occur.

Chlorine gas (Cl2) will accept electrons to form Cl- ions.

The Iron(II) ions (Fe2+) will lose electrons to form Fe3+ ions. (Iron (III) ions)

Fe2+ ions are green, while Fe3+ ions are yellow,

so the observation will be the solution turning from green to yellow.

The airplanes parts and functions​
SpyIntel [72]

Answer: The main sections of an airplane include:

fuselage: The plane’s body, or fuselage, holds the aircraft together, with pilots sitting at the front of the fuselage, passengers and cargo in the back.

Wings: An aircraft’s wings are critical to flight through the production of lift, but they have many parts of the wing to control this lift amount and direction.

Cockpit: The cockpit is the area at the front of the fuselage from which a pilot operates the plane

Engine: The engine(s), or powerplant, of an aircraft creates thrust needed for the plane to fly.

Propeller: An aircraft’s propeller(s) are airfoils, similar to a wing, installed vertically to create thrust to drive the plane forward.

Tail assembly: An aircraft’s tail is mainly used for stability, as well as creating lift in combination with the wings. It’s comprised of several parts.

Landing gear: Landing gear is located under the belly of the plane consisting of a wheel and strut to soften impact with the ground and may be retractable into the fuselage.

Mg + 2H20 + Mg(OH)2 + H2 + 353kJ
mixer [17]

Answer:

m_{H_2O}=8.9g

Explanation:

Hello,

Based on the given reaction, since magnesium and water are in a 1:2 molar ratio at the reactants, we must apply the following stoichiometric factors to compute the complete reaction of the 6.0 g of magnesium:

m_{H_2O}=6.0gMg*\frac{1molMg}{24.305 gMg}*\frac{2molH_2O}{1molMg} *\frac{18gH_2O}{1molH_2O} \\\\m_{H_2O}=8.9g

Best regards.
