C. Metals higher in the series will replace metal ions in solution that
are lower in the series.
Explanation:
The activity series of metals shows the extent of reactivity of different metals.
On the activity series, the most reactive metals are located higher up on the able whereas the less reactive ones are found at the bottom of the series.
- We can tell if single displacement reactions will occur by simply looking at the reactivity series.
- Metals that are more reactive will displace the ones that are not very reactive that are positioned down the series. Such a reaction will occur.
- Metals lower in the series cannot displace the ones on top because they are less reactive. Such a reaction will not occur.

Standard Molar Volume is the volume occupied by one mole of any gas at STP. Remember that "STP" is Standard Temperature and Pressure. Standard temperature is 0 &176:C or 273 K. Standard pressure is 1 atmosphere or 760 mm Hg (also called "torr"). 1 mole of any gas at STP occupies 22.4 liters of volume.
Answer:
Conservation of Mass
Explanation:
Conservation of Mass -
According to the works of Antoine Lavoisier , he stated that , mass is always conserved in a chemical reaction .
For example ,
carbon reacts with oxygen , it forms carbon dioxide ,
But , by using the principle of conservation of mass ,
mass can not created or be destroyed , hence , the mass of the initial state and final remains constant , there is only the transfer of mass or matter .

Answer: The mass in grams of sodium carbonate is 34.3 g
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.
where,
n = moles of solute
= volume of solution in ml
moles of =
Now put all the given values in the formula of molarity, we get
Therefore, the mass in grams of sodium carbonate is 34.3 g
