AC2
A will lose 2
C will gain 1
Need two Cs to match A
Answer:

Explanation:
Hello,
In this case, as the reaction between sodium hydroxide and sulfuric is:

We can notice a 2:1 molar ratio between the base and the acid, for that reason for the titration at the equivalence point we find:

Which in terms of concentrations and volumes is:

In such a way, solving for the required volume of base we find:

Best regards.
Answer:
The answer to your question is letter C.
Explanation:
Reaction
Potassium hydroxide = KOH
Barium chloride = BaCl₂
Potassium chloride = KCl
Barium hydroxide = Ba(OH)₂
KOH + BaCl₂ ⇒ KCl + Ba(OH)₂
Reactant Elements Products
1 K 1
1 Ba 1
2 Cl 1
1 H 2
1 O 2
The reaction is unbalanced
2KOH + BaCl₂ ⇒ 2KCl + Ba(OH)₂
Reactant Elements Products
2 K 2
1 Ba 1
2 Cl 2
2 H 2
2 O 2
Now, the reaction is balanced
Answer : The balanced redox reaction will be,

Explanation :
The given chemical equation is,

In the half reaction method, the number of atoms in each half reaction and number of electrons must be balanced.
The half reactions in the acidic medium are :
Reduction :
......(1)
Oxidation :
.......(2)
Now multiply the equation (2) by 4 and then added both equation, we get the balanced redox reaction.
Thus, the balanced redox reaction will be,

A beta particle.<span>β
</span> Looking at the particles before and after for the decay, you'll see that there is a total of 214 neutrons and protons both before and after the radioactive decay. But you'll also see that before the decay, there were 82 protons and after the decay, there are 83 protons. So a neutron was converted to a proton which means that a negative charge had to be emitted, so it's a beta decay where a neutron emits a beta particle (an electron). The beta particle can be represented as a greek beta <span>β</span> followed by a minus sign, giving β-, or as a "e" followed by a minus sign, so e-
