The brother is represented by variable b.
The sister is represented by the variable s.
This means:
b+s=26
Answer: 
moles
Explanation:
We are given:
Moles of electron = 1 mole
According to mole concept:
1 mole of an atom contains 
number of particles.
We know that:
Charge on 1 electron = 
Charge on 1 mole of electrons = 
The metal being plated has a +4 charge, thus the equation will be:
of electricity deposits = 1 mole of metal
Thus 861.8 C of electricity deposits =
moles of metal
Thus moles of metal should be plated
<h2>
Answer:B</h2>
Explanation:
A solution is a homogeneous mixture of two or more substances. A solution may exist in any phase.A solution has two components.The minor component solute is dissolved in a major component called solvent.
Any option that claims against this definition is wrong.
option A:
Since the solution is homogeneous,it has same properties throughout.
option B:
Solutions contain solute dissolved in solvent not solvent dissolved in solute.
option C:
The solution can be in any phase.
option D:
Solutions are a kind of mixtures because they have no chemical interactions among the solute and solvent particles.
So,option B is wrong.
Hey there!:
1) The additional stability that accompanies the formation of the network<span>Crystalline is measured as network enthalpy.
</span>2) The reticular energy is the energy released when the solid Crystal isform from separate ions in the gaseous state. Always exothermic.<span>
3) </span>The enthalpy of the network depends directly on the size of the loads and conversely in the distance between the ions .
hope this helps!
