Answer:
Explanation:
Hello!
In this case, since the reaction between two aqueous solutions may turn out in the production of a solid precipitate, for potassium carbonate and calcium chloride, calcium carbonate is precipitated out as shown below:
Now, since the two reactants are in a 1:1 mole ratio, we infer they react in the same proportion, thus we compute the reacting moles, considering the used volumes of those molar solutions:
Thus, since just 0.00465 mol out of 0.00502 moles of calcium chloride are consumed, the potassium carbonate is the limiting reactant, therefore the mass of yielded calcium carbonate (molar mass = 100.09 g/mol) is:

Answer:
B.) Chemical
Explanation:
The energy stored in the bonds between atoms is referred to as chemical energy. I hope this helps! ^-^
Answer:
Moving from left to right across a period, the atomic radius decreases. The nucleus of the atom gains protons moving from left to right, increasing the positive charge of the nucleus and increasing the attractive force of the nucleus upon the electrons.
C. They come from energy sources that never run out.
Answer:
Carbon is non metal because it is found in the right side of the periodic table while calcium is metal because it is found in the left side of the periodic table.
