The balanced chemical reaction is:
Zn + 2AgNO3 = Zn(NO3)2 + 2Ag
To determine the amount of the reactant left, we have to determine which is the limiting and the excess reactant. We do as follows:
5.65 g Zn ( 1 mol / 65.38 g) = 0.09 mol Zn
21.6 g AgNO3 (1 mol / 169.87 g) = 0.13 mol AgNO3
The limiting reactant would be silver nitrate since it is consumed completely in the reaction. The excess reactant would be zinc.
Excess Zinc = 0.09 mol Zn - (0.13 / 2) mol Zn = 0.025 mol Zn left
Answer:
Explanation:
Each coil increases it by a multiple of 100.
=> 50 | 3 | <u><em>15,000</em></u>
=> 100 | 3 | <u><em>30,000</em></u>
=> 150 | 3 | <u><em>45,000</em></u>
Answer:
The molar mass and molecular weight of Sn(CO3)2 is 238.728.
Explanation:
Answer:
Metal more reactive than non metal
In acidic solutions you have H+ but in basic solutions you have OH-.
You need know that for to balance the reaction.
