Answer:
.
Explanation:
Electrons are conserved in a chemical equation.
The superscript of 
indicates that each of these ions carries a charge of 
. That corresponds to the shortage of one electron for each 
ion.
Similarly, the superscript 
on each 
ion indicates a shortage of three electrons per such ion.
Assume that the coefficient of (among the reactants) is 
, and that the coefficient of (among the reactants) is 
.
.
There would thus be silver (
) atoms and aluminum (
) atoms on either side of the equation. Hence, the coefficient for 
and 
would be 
and 
, respectively.
.
The ions on the left-hand side of the equation would correspond to the shortage of electrons. On the other hand, the 
ions on the right-hand side of this equation would correspond to the shortage of 
electrons.
Just like atoms, electrons are also conserved in a chemical reaction. Therefore, if the left-hand side has a shortage of electrons, the right-hand side should also be electrons short of being neutral. On the other hand, it is already shown that the right-hand side would have a shortage of electrons. These two expressions should have the same value. Therefore, 
.
The smallest integer and that could satisfy this relation are 
and 
. The equation becomes:
.
I'm not the best with science but I believe the answer is B. Na.
Answer:
1.) At high altitude it takes longer to cook spaghetti.
Explanation:
The first even describes depression in boiling point due to reduction in external pressure . It is not a colligative property.
Depression of freezing point and elevation of boiling point due to impurity or addition of solute are colligative priperty.
c. physical change
Explanation:
The separation of ink into its different pigments during chromatography is a physical change.
Ink is a mixture of many different pigments.
During chromatography, a mixture is separated based on the relative migration of constituents of mixture over an adsorbent.
- Separation techniques are used to celebrate mixtures based on their physical properties.
- During a physical change only the physical properties of matter like their form and state is changed.
- The process is easily reversible and no new kinds of matter are formed.

Consideing the definition of velocity, the total velocity is 43.75 miles/h.
<h3>Definition of velocity</h3>
Velocity is a physical magnitude that relates the displacement of an object, the time it takes to make this change in position and direction.
The velocity can be defined as the amount of space traveled per unit of time with which a body moves, considering the direction, and can be calculated using the expression:
velocity= distance traveled÷ time
Velocity has units of 
.
<h3>Velocity in this case</h3>
In this case, you know:
- distance traveled= 350 miles
- time= 8 h
Replacing in the definition of velocity:
velocity= 350 miles÷ 8 h
Solving:
<u><em>velocity= 43.75 miles/h</em></u>
Finally, the total velocity is 43.75 miles/h.
