Answer:
AgNO3
Explanation:
Considering the equation:
2 AgNO3(aq) + CuCl2(aq) ––> Cu(NO3)2(aq) + 2 AgCl(s)
2 moles of AgNO3 reacted with 1 mole of CuCl2
divide the moles by two
1 mole of AgNO3 will react with 0.5 mole of CuCl2
then
0.5 mole AgNO3 will react with 0.25 mole of CuCl2 and limiting reagent is the reagent that is consumed when the reaction is completed.
Going by the calculation above the limiting reagent is AgNO3
According to Coulomb's Law, as the atomic number increases within a series of atoms, the nuclear attraction for electrons will also increase, thus pulling the electron(s) closer to the nucleus.
Answer:
Na
Explanation:
To find the limiting reactant we must first write the balanced chemical reaction. It must be correctly balanced so that we can find the proper mole ratios.
2 Na + H₂ → 2 NaH
After this we will convert our measurements to moles. For mass we do this by dividing by the molar mass.
6.75g ÷ 22.99 = 0.294mol Na
3.03g ÷ 2.02 = 1.50mol H₂
Now that we have the moles of each of the reactants, we can multiply them by their mole ratio with a reactant.
0.294mol Na ×
= 0.294mol NaH
1.50mol H₂ × 2/1 = 3.00mol NaH
Na is our limiting reagent because it makes the smaller amount of moles.
Answer:
During charging by conduction, both objects acquire the same type of charge. If a negative object is used to charge a neutral object, then both objects become charged negatively. In order for the neutral sphere to become negative, it must gain electrons from the negatively charged rod. 3.
