Correct answer is 3: 8 (2x + 3y)
Answer:
Metals which react with steam form the solid metal oxide and hydrogen gas.
In general, the more reactive the metal, the more rapid the reaction. Aluminium is unusual, because it is a reactive metal that does not react with water. Its surface forms a protective layer of aluminium oxide that keeps water away from the metal below.
The apparatus used to react a metal with steam and collect the gas produced is shown below.
Answer:
x = 55°
Step-by-step explanation:
From given figure we have
Two lines parallel
As we know simple straight line maintain an angle of 180°
Third line bisecting the two parallel lines at different position
But hold same same angle form both because lines are parallel.
To find angle = 180 - 125 = 55
Oh that's easy it is 106 times 10^6
