Answer:
The obtained result indicates that the hydrogen atom is not equal on both sides. Thus the reaction is not balanced.
Explanation:
Answer:
Aluminum oxide has a chemical formula ai2o3, it is used in various chemicals.
Explanation:
To solve this problem, we must assume ideal gas behaviour so
that we can use Graham’s law:
vA / vB = sqrt (MW_B / MW_A)
where,
<span>vA = speed of diffusion of A (HBR)</span>
vB = speed of diffusion of B (unknown)
MW_B = molecular weight of B (unkown)
MW_A = molar weight of HBr = 80.91 amu
We know from the given that:
vA / vB = 1 / 1.49
So,
1/1.49 = sqrt (MW_B / 80.91)
MW_B = 36.44 g/mol
Since this unknown is also hydrogen halide, therefore this
must be in the form of HX.
HX = 36.44 g/mol , therefore:
x = 35.44 g/mol
From the Periodic Table, Chlorine (Cl) has a molar mass of
35.44 g/mol. Therefore the hydrogen halide is:
HCl
<span>The incubation of eggs in nests is one adaptation of birds to land. The statement that is presented is True. Incubation basically happens when a certain oviparous animals hatch their eggs and to the development of the embryo within the egg.</span>
