Answer:
double replacement occurs
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
Short answer: nitrogen, oxygen, Argon, and
inert gas
The atmosphere contains many gases, most in small amounts, including some pollutants and greenhouse gases.
These contribute to climate change.
The volume<span> of </span>gas<span> because of the </span>increase<span> and decrease in the speed in which the molecules bounce around. ... Boyle's Law states that if temperature stays the same, the </span>amount of<span> space a </span>gas takes up will increase<span> if the </span>pressure<span> decreases. The </span>amount of gas<span> will take up less space if the </span>pressure<span> is increased. this would be the correct answer </span>
