Answer:
Amount of
produced will be half of its original value.
Explanation:
Balanced reaction: 
According to balanced equation, 1 mol of HCl reacts with 1 mol of NaOH to produce 1 mol of 
If amount of reactants (NaOH and HCl) are halved then we can write-
0.5 mol of HCl reacts with 0.5 mol of NaOH to produce 0.5 mol of
.
So, it is evident that amount of
to be produced will be half if amount of reactants are halved.
Answer:
I think it's letter B
Explanation:
Hope it helps correct if I'm wrong
When a large fissile atomic nucleus such as uranium-235 or plutonium-239 absorbs a neutron, it may undergo nuclear fission. The heavy nucleus splits into two or more lighter nuclei, (the fission products), releasing kinetic energy, gamma radiation, and freeneutrons
To get this it helps to know the electronegativity numbers of the elements but it isn't required. You just need to know that Fluorine is the most electronegative element and that the farther away from Fluorine you are on the periodic table, the less electronegative you get. The one exception to this rule is hydrogen with actually has an electronegativity of 2.1 while lithium has one of 1.0. Also the higher difference in electronegativity between two atoms the more polar the bond is.
Now to start the question. H-Br could be a contender since H has an electronegativity number of 2.1 and Br is relatively close to Fluorine so we'll put that one aside for now. H-Cl knocks out A because both bonds have H but one bond has Br and the other has Cl. Cl is closer to Fluorine than Br so answer B is the contender now. For answer C, I and Br are too close to have a higher electronegativity difference than H-Cl so that one isn't it. Finally for answer D, I is much closer to Cl than H is so the electronegativity difference is much less, making your answer B.
