Answer:
= 29.64 g NaNO3
Explanation:
Molarity is given by the formula;
Molarity = Moles/Volume in liters
Therefore;
Number of moles = Molarity × Volume in liters
= 1.55 M × 0.225 L
= 0.34875 moles NaNO3
Thus; 0.34875 moles of NaNO3 is needed equivalent to;
= 0.34875 moles × 84.99 g/mol
= 29.64 g

Answer:
The answer is endothermic as the heat flows into the system from the surroundings. The products are at higher energy than the reactants, as they have absorbed energy.
H is the answer which represent a pair of isotopes
The reaction of calcium and sodium chloride would yield to calcium chloride and sodium metal. It would be expressed as:
Ca + NaCl = CaCl2 + Na
To have the complete balanced reaction, it should be balanced where the number of each atom in the reactant side and the product side would be equal. The balanced chemical reaction would be:
Ca + 2NaCl = CaCl2 + 2Na
As we can see we have 1 calcium atom in each side, 2 sodium atom and 2 chlorine atoms in each side. This reaction is an example of a single displacement reaction where calcium displaces sodium and bonding with the chloride ion forming another salt.
